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

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.

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

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.

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.

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.

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.

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.
