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.

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

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.

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.

Spherical Roller Bearings

Spherical roller bearings are double row units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. We stock both the plain (symmetrical) bore (EAW33) and taper bore (EAKW33).
The symmetrical barrel rollers orientate themselves freely on the concave outer raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.

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.

4300 Series Double Row Radial Contact Ball Bearings

Self-Aligning Ball Bearings

2200 & 2300 Series self-aligning ball bearings are double row with a concave raceway to allow approximately 4° of misalignment. They have a tapered bore for use with adaptor sleeves. There are also a range of sealed versions available.

Cylinder Bore

SNR Shaft Seals & Adaptors

Cover plates are made of corrosion-resistant steel and used where the shaft terminates inside the housing. In this configuration only one seal set will be required.

Cover Plates

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.
