C3 clearance, J-steel cages and quiet running characteristics available in JEM bearings. They are relatively simple in design, non-separable, capable of operating at high and even very high speeds, and require little attention or maintenance in service provided the customer selects the appropriate bearing specifications for his application. These characteristics coupled with a price advantage make deep groove ball bearings the most popular of all rolling bearings.

SKF produces deep groove ball bearings in a large number of designs and sizes. Catalogi most numerous are the single row bearings without filling slots Conrad assembly. The bearings with filling slots described in the section starting on page 47 are used in special applications and consequently only a limited range is produced.

These products are most frequently used in high-speed applications or where precision is critical as in cutting tools, electric motors, handheld tools, and spindles. ABEC 5 bearings are produced in the and series and are available in an open version only. They can be supplied with either a brass Y or phenolic TC cage.

Product highlightsFast, quiet, robust bearingsIf the application is demanding and quiet running, smoothness, strength and low heat generation are mandatorySKF deep groove ball bearings fit the bill.

Deep groove ball bearings with filling slots Max type Single row deep groove ball bearings with filling slots incorporate a greater number of balls than the corresponding size without filling slot, and have a filling slot in both outer and inner rings.

The radial load carrying capacity is higher than that of bearings without filling slot, but their axial load carrying capacity is small. They are also unable to operate at the high speeds normally associated with deep groove ball bearings. SKF deep groove ball bearings with filling slots are available in various designs to meet market demands. The most common are described below Figure 2 and are listed in the tables on page Quiet runningHigh precision balls and specially designed raceway grinding equipment are used by SKF to produce some of the quietest running bearings available.

Quality performance in demanding applicationsCapable of meeting the severest demands in terms of operating speed, operating temperature, vibration, high running accuracy, low friction, and the ability to function in a contaminated environment with available seals and shields.

Basic designDeep groove ball bearings, single rowSKF single row deep groove ball bearings have deep, uninterrupted raceways and a high degree of conformity between balls and raceways.

This enables them to carry axial loads in both directions in addition to radial loads even at rolamsntos speeds. Single row deep groove ball bearings are suitable for a wide variety of applications and are therefore produced in a large number rolamenos sizes and designs.

Single row deep groove ball bearings of the basic design, i. Those bearings of the basic design which are also produced as shielded or sealed bearings may, for manufacturing reasons, have recessed outer ring shoulders to take the shields or seals. Optimized internal geometryThe internal geometry has been optimized for longer life, quieter running, improved seal attachment, low friction and increased ability to accommodate slight misalignments without reducing bearing automoivos.

The shields are made of sheet steel and normally have a cylindrical extension in the shield bore to form a long sealing gap with the inner ring shoulder. Shielded bearings are primarily intended for applications where the inner ring rotates.

If the outer ring rotates, there is a risk that the grease will leak from the bearing at high speeds. Bearings in the 60, 62 rolamrntos 63 series up to 52 mm outside diameter are equipped with RSH seals to design catalogp. Other bearings have RS1 seals, which seal against the cylindrical surface of the inner ring shoulder b indicated by dimension d1 in the product table or against a recess in the inner ring side face c indicated by dimension d2 in the product table.

The seals are inserted in recesses in the outer ring and provide good sealing at this position without deforming the outer ring. Standard seals are made of acrylonitrile butadiene rubber NBR with a sheet steel reinforcement. When sealed bearings are operated under extreme conditions, e. For bearing arrangements where this would be detrimental, special design steps must be undertaken, please consult the SKF application engineering service.

These fumes can be harmful if inhaled, as well as to the eyes. In addition, once the seals have been heated to such temperatures, they are dangerous to handle even after they have cooled and should not touch the skin. If it is necessary to handle bearings with seals that have been subjected to high temperatures, such as when dismounting the bearing, the following safety precautions should be observed: Always wear protective goggles, gloves and appropriate breathing apparatus, Place the remains of the seals in an airtight plastic container marked with a symbol for material will etch, Follow the safety precautions in the appropriate material safety data sheet MSDS.

If there is unintentional contact with the seals, wash hands with soap and plenty of water and flush eyes with plenty of water and consult a doctor immediately. If the fumes have been inhaled, consult a doctor immediately. The user is responsible for the correct use of the product during its service life and its proper disposal. SKF takes no responsibility for the improper handling of fluoro rubber seals or for any injury resulting from their use. Bearings in the 60, 62 and 63 series up to 52 mm outside diameter are equipped with RSL seals to design a.

Other bearings have RZ seals b. The seals form an extremely narrow gap with the cylindrical surface of the inner ring shoulder or recess profile and are practically noncontracting.

Because of this, bearings fitted with low-friction seals can be operated at the same high speeds as bearings with Z shields, but with improved seal performance. The low-friction seals are made of oil and wear-resistant acrylonitrile butadiene rubber NBR with a sheet steel reinforcement. Figure 3Bearings with snap ring grooveDeep groove ball bearings with a snap ring groove can simplify arrangement design as the bearings can be axially located in the housing by a snap or retaining ring Figure 6.

Appropriate snap rings are shown in the product table with designation and dimensions and may be supplied separately or already mounted on the bearing.

The bearings are lubricated for life and are maintenance free. They should on no account be heated to temperatures above F Cnor should they be washed. By special order, bearings with shields or seals can be supplied with other greases, e. Open bearings are supplied with a rust preservative that is compatible with most standard greases and should not be removed prior to mounting or lubricating.

MassesThe masses given in the tables are for the basic design of the bearing. The mass of bearings with shield sseal s or snap ring groove differs only slightly from that of the basic bearing. Internal clearanceRadial internal clearance Table 1 SKF single row deep groove ball bearings are produced with Normal radial internal clearance CN or C0 not marked on bearing as standard.

Radial clearance selection is based on factors such as high speed, operating temperature, shaft fits and axial movement limitations. The availability of bearings with clearances other than Normal should be checked before ordering. Many of the bearings, particularly the smaller sizes, are also available with radial internal clearance, which is greater than C3 or less than C2 Normal. The values of the clearance limits for single row deep groove ball bearings are shown in Table 1 and the values of the clearance limits for max type ball bearings are shown in Table 3 on page The values apply to unmounted bearings under zero measuring load.

Table 1 Radial internal clearance of deep groove ball bearingsBore diameter d over incl. If the bearings are mounted with the usual fits tolerance j5 to n6 depending on shaft diameter, and J7 for the housing the values of e, X and Y given in Table 2 can be used to calculate the equivalent load.

If a clearance greater than Normal is chosen because a reduction in clearance will be obtained in operation, for example, as a result of strong heating of the inner ring, then the values of the factors under Normal clearance should be used. The requisite minimum radial load to be applied in such cases can be determined by using the Interactive Engineering Catalog on the SKF website www. However, the weight of the components supported by the bearing, together with the external forces, often exceeds the requisite minimum load.

If this is not the case, an additional radial load must be applied to the bearing; for example, by increasing belt tension, by applying a preload to the inner or outer aitomotivos, or by using springs. Frequency vibration dataFrequency vibration data is available sutomotivos the SKF website www. This is also true of deep groove ball bearings, particularly if they run at high speeds where the inertia forces of the balls and cage, and the friction in the lubricant can have a detrimental influence on the rolling conditions in the bearing automottivos may cause damaging sliding movements to occur between the balls and the raceways.

Single row angular contact ball bearings are designed to accommodate axial loads acting in one direction. Under radial loads, an induced force acting in the axial direction is produced which must be counteracted. Consequently, the single bearings are normally adjusted against a second bearing.

SKF angular contact ball bearings are produced in a wide variety of designs and sizes. Those commonly used in general engineering are shown in this catalog: Single row bearings Double row bearings Four-point contact ball bearings Thrust packAngular contact ball bearings, single rowSingle row angular contact ball bearings can accommodate combined loads however the ksf loads can only act in one direction Xkf 1.

Catalkgo radial loads, a force acting in the axial direction is produced which must be counteracted. Consequently, the bearings are normally adjusted against a second bearing. The single row angular cata,ogo ball bearings shown in the tables have one high and one low shoulder on each ring, enabling a large number of balls to be incorporated. This gives the bearings relatively high load carrying capacity.

The contact angle is 40 suffix B and the bearings are therefore suitable for heavy axial loads.
