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

Adapter sleeves are commonly used for locating tapered bored bearing and securing them to a shaft. They can be accurately positioned and dismounted. By using in conjunction with SNR feeler gauges accurate radial clearances will be achieved.

Adaptor Sleeves

Self-Aligning Ball Bearings

2200 & 2300 Series self-aligning ball bearings are double row with a concave raceway to allow approximately 4° of misalignment. These are cylindrical type but are also available with seals & taper bore for use with adaptor sleeves.

Taper Bore

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 Inner Ring and Outer Ring is without Ribs

V-Grooved Pulleys for Taper Bushes

Grooves to ISO/BS/DIN 2211.

Belt Section 13/A (SPA/13)

Conti-V Standard Multiflex V-Belts

Classical section wrapped V-belts to DIN 2215. Moderately oil-resistant. Resistant to temperatures from -55C to +70C. Electrically conductive (anti-static) to ISO 813. Insensitive to dust. Suitable for tropical climates.

Belt Section 13/A (SPA/13)

Max Width (b1) 13mm, Height (h)8mm.

Taper Bore Bushes

Used to fit flywheels, pulleys and chain sprockets onto an electric motor shaft.
Taper Bore Bushes are easily assembled and are an ideal method of mating to a shaft without the need for machining.
To lock the shaft tighten up two grub screws,
to unlock it you remove the screws, inserting one in the third hole and wind in to lever off the hub from the shaft.
Material: EN-GJL 200/DIN EN 1561.

Metric Sizes

Keyways to DIN 6885 Part 1.
* Bores marked have shallow keyways.

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

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.

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.
