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.

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.

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.

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.

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 - Taper Bore

Double Row Angular Contact Ball Bearings

Self-aligning ball bearings are double row with a concave raceway to allow approximately 4° of misalignment. Available with cylindrical and tapered bore for use with adaptor sleeves.There are also a range of sealed versions available.

Thrust Ball Bearings

Thrust Bearings are designed primarily to support axial loads at contact angles between 30° and 90°. Just as with radial bearings, these bearings differ according to the type of rolling element they use. With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping movement between the bearing's rolling element and raceways.
Comprising of caged ball bearing element and pair of shaft housing washers (bearing shaft washer and housing washer, and the normal contact angle is 90°. Axial loads can be supported in only one direction, radial loads cannot be accommodated. Spherical roller and needle roller versions are also available.
