ARB Cylindrical Roller Bearing NUP310 Series

ARB Cylinderical Roller Bearing are available in a wide range of designs. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials. They can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life. We also offer sealed or split cylindrical roller bearings to protect your product from all kinds of dirt, water, dust and moisture.

Cylindrical roller bearings have rollers that are “split” into two halves, which are located on opposite sides of the bearing races. This design allows them to accommodate axial displacement, or movement in the direction parallel to the axis of rotation. They also offer high stiffness, low friction and long service life. The bearings can meet the challenges of applications faced with heavy radial loads and high speeds.

The most common cylindrical roller bearings have a single row of rollers, but there are variations with two to four rows available. The inner/outer ring flanges as well as cage designs and materials all need to be taken into considerations when selecting a cylindrical roller bearing for your application. Smaller bearings tend to be less expensive than larger ones. Other variations include sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.
