SNR Deep Groove Ball Bearings

With Shields

Self Aligning Bearings

With double ball rows and a spherical raceway in the outer ring, self-aligning ball bearings can compensate for installation errors or shaft misalignment. Useful for applications requiring high rotating speeds while exercising moderate radial, and moderate or low axial loading. Available in cylindrical bore or taper bore (K suffix). Clearance is standardised (ISO 5753). The values are different for cylindrical bore and tapered bore bearings (suffix K). The latter have a significantly larger clearance to allow the reduction in clearance resulting from the adapter sleeves interference fit.

Self Aligning - Plain Bore

SNR Bearings

SNR double-row ball bearings have become the natural substitute for single-row ball bearings for higher radial load applications, or for axial loads in both directions. Suitable for mean rotating speeds, these bearings only admit very slight misalignment between shaft and housing, to the order of 0.06.
Standard synthetic material cage.

Applications: electrical motors, household appliances, wood-machine spindles, small reduction gears.

4200 Series Double Row Radial Contact Ball Bearings

Deep Groove Ball Bearings - C3 Clearance

C3 bearings have an additional internal radial clearance to cope with high speed environments where excess heat is generated.

Open type:

Without seals to allow for the free circulation of either oil or grease.

Single Row Deep Groove Ball Bearings - C3 Internal Clearance

C3 Bearings have an internal clearance to cope with high speed environments where excess heat is generated.

Shielded Type

With metal shields inserted into the outer raceway, these fit in closely to the inner race providing moderate protection against mechanical damage, and against the ingress of moisture, dust and other foreign objects. The shields also retain the pre-filled grease in the bearing. Shields can be easily removed for applications that only require one shield.

Single Row Deep Groove Ball Bearings - C3 Internal Clearance

C3 Bearings have an internal clearance to cope with high speed environments where excess heat is generated.

Open Type

Without seals to allow for the free circulation of either oil or grease, used in gearboxes and other assemblies where a lubricant is already present.

SNR Deep Groove Ball Bearings

Rubber seals inserted into the outer raceway and in contact with the inner race providing protection against the ingress of moisture, dust and other foreign objects.
