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.

Lock Nuts

Used primarily to help lock and locate bearings on shafts or adaptor sleeves. They have evenly spaced slots on the circumference for use with the SNR range of hook spanners.

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.

Rubber sealed type:

With 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. The seals also retain the pre-filled grease in the bearing. Seals can be easily removed for applications that only require one seal.

SNR Shaft Seals & Adaptors

The SNR SC...SV series consists of a contact washer made of corrosion-protected steel with a vulcanised rubber lip to locate in the housing.

The V-Ring seal has axial contact after being fitted to the shaft with the face of the washer. If the shaft extends through the housing one seal pack must be
ordered for both side of the housing.

Other sealing arrangements are available through your local service branch.

Taper Roller Bearings

Tapered roller bearings are comprised of solid inner and outer rings with raceways, taper rollers and cages manufactured from pressed steel. The bearings are not self-retaining. As a result, the inner ring with the rollers can be fitted separately from the outer ring. Tapered roller bearings are not sealed and not supplied grease filled.

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.

Taper Roller Bearings

Tapered roller bearings are comprised of solid inner and outer rings with raceways, taper rollers and cages manufactured from pressed steel. The bearings are not self-retaining. As a result, the inner ring with the rollers can be fitted separately from the outer ring. Tapered roller bearings are not sealed and not supplied grease filled.

Tab Washers

Tab washers are used for securing KM series lock nuts. They have an inner tab for location on the adaptor sleeve. One of the external tabs is bent over a slot when used wit the
KM series lock nuts.

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.

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.

SNR Bearings

SNR has developed a complete range of high quality ball thrust bearings. Thrust bearings are designed to maintain the shaft in one single direction. They admit low rotating speeds and sustain high axial loads.

You are strongly advised against submitting them to radial loading. Ball thrust bearings are comprised of separate items facilitating installation and maintenance. Grease and oil lubrication is feasible.

Applications: vertical shaft, lathe tailstock, plate-type pumps.
