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.

SNR Pillow Block Housings

The housings are produced from grey cast iron in compliance with DIN EN 1561 and external surface painted RAL 5010 - Gentian Blue) the machined surfaces are treated with an anti-corrosion agent. Threaded for grease nipple or automatic lubrication and grease drain hole which is sealed with a metal threaded plug at the factory but can be removed subject to application.
Housings based on ISO 113/II: 1994 and DIN 736: 1984 to DIN 739: 1984.

500 Series for use with tapered bore from 1200K, 2200K, 22200K and 23200K with shaft diameter: 20mm to 140mm. 600 Series for use with tapered bore from 1300K, 3200K, 21300K and 22300K with shaft diameter: 20mm to 90mm.

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.

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.

51200 Series Ball Thrust 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.

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.

Double-row Self-Aligning Ball Bearings - Sealed Type

The spherical race in the outer ring allows angular displacement. It has good ability to withstand radial loads. Its design, however, means that it can only accept very low axial loads. These bearings are pre-greased but seals limit angular travel possibilities to 1/20. Basic loads are the same as the series 12 and 13 bearings of the same diameter, as they have the same internal design definition. The misalignment angle must nevertheless be limited in order to remain within values compatible with the sealing system used, the permissible misalignment is limited to 0.5

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.

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.
