The Cylindrical roller bearings by SNR include several variants to permit accurate bearing selection thus, improving machine efficiency. These roller bearings are recommended for high radial load and high rotating speed applications.
The standard series is made of standard polyamide 6.6 cage with 25% glass fiber, while the series 4 is made of standard steel sheet cage. There is an optional machined brass cage available. Large size bearings are fitted with a machined brass cage.
For special applications that prevents the use of synthetic cages, a metallic cage can be provided on request. The bearings have standard sealing. Special seals are also available upon request. The variable clearance depends on the Series. Axial clearance is only for bearings of NUP type, and limited by 4 internal shrouds.
