Metric PB Series Bearings

Introduction

When factors such as cost, availbility, corrosion resistance, tighter tolerances, torque, seal/shield options, and temperature resistance are important in your application, it pays to consider PB series four- point contact metric ball bearings as an alternative to cross-roller bearings. The additional design flexibility they offer can often help you achieve your design objectives with optimum performance and economy.

Optimize Your Design Options


With additional features not commonly available in standard cross-roller bearings, PB series bearings provide greater design flexibility.

Seals/Shields

Standard industry seals are generally available from nitrile rubber. PRS can also provide custom seals manufactured from silicone materials for applications where high temperature or extreme environments are likely to be encountered.

PRS PB Metric Series four-point contact ball bearings are dimensionally interchangeable with cross-roller bearings. PB series bearings are available to match the bores and widths of common cross roller bearings.

Separators

The common roller spacer for many cross-roller bearings is a non-metallic composite. High temperature and/or horizontal axis applications, however, require nonstandard materials or a non-
standard separator design. PRS four-point contact ball bearings are available with separator options to meet a wide range of applications.

Internal Fitup

PRS can help you optimize internal fitup of our PB series four-point contact ball bearings to provide the desired operating performance. Pre-loaded bearings are recommended for greater stiffness, and diametral clearance is recommended for lower torque applications.

Note : 

Standard bearings are supplied without seals and shields, and they are assembled with a light clearance. Alternate features can be obtained by adding the following suffix letter to the basic part number.

U=single seal

CO=standard clearance

CCO=preload

UU=double seal 

CI=greater than standard clearance
