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.

SNR Shaft Seals & Adaptors

SNC bearing housings can be used for both fixed and floating bearing arrangements. Locating rings enable the bearing to be fixed in place axially. The width of the locating rings is adapted to the bearing being used. To secure the bearings, two locating rings per housing are required.

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

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.

Cylindrical Roller Bearings

Single row cylindrical roller bearings with inner and outer rings. Several styles are available in this series with one or two ribs on either the inner or outer rings. These can support high radial loads and higher speeds due to the cage design than the full compliment designs. The bearings are separable and easier to fit and dismantle.

Non-Locating Type with two Ribs on Outer Ring and Inner Ring is without Ribs

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.

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.

Housed Bearing Units

Housed Bearing Units are one of the most effective and easiest solution to accomodate misalignment. Units below consist of housing and insert. A wide range is available including Imperial sizes. Please ask for further information.

Plummer Blocks - Short Base - SNP Type

Cast iron self lube unit plummer blocks. With two slotted holes for fixing.

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.

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.

Angular Contact Ball Bearings

Single row angular contact bearings have the raceways arranged that the forces are transmitted from one raceway to the other at a specific contact angle and can only support axial forces in one direction. They must be axially adjusted against a second bearing fitted in a mirror image.
