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.

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.

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.

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.

Roller Chain

Renold Blue Box chain with their unique control over pin/bush contact, ensures that little initial chain adjustment is therefore required. Renold Blue Box roller chain is highly fatigue resistant with breaking loads exceed the minimum requirements of the international standards.
The specification of Renold chain has evolved from decades of design, test and application experience which delivers product reliability and consistency. Other sizes from 5/16” to 2” pitch are also available please ask for details.
Conforms to: DIN8187/IS606

Duplex Chain

Narrow Section Wrapped V-Belts conform to DIN 7753 and BS 3790. Moderately oil-resistant. Resistant to temperatures from -55C to +70C. Electrically conductive (anti-static) to ISO 1813. Insensitive to dust. Suitable for tropical climates.

Conti-V Ultraflex V-Belts

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.
