PWTR1542-2RS track roller bearings Support rollers, with flange rings, with an inner ring

Short Description:

PWTR …2RS design support rollers are based on double row full complement cylindrical roller bearings.They have an outer ring with three integral flanges, which guide the roller sets axially and an inner ring with two loose flange rings, which guide the outer ring axially via the roller sets.
Have a relatively large grease quantity between the two roller sets and are fitted on both sides with an NBR contact seal, being integral with a sheet metal angle ring that is pressed into the outer ring shoulder:
To press against the flange rings.
Extending over the flange rings, making the support roller non-separable.
Can accommodate relatively heavy axial loads that can occur because of skew or tilting.

The Features of PWTR1542-2RS Support rollers, with flange rings, with an inner ring

Since the bearing has not got a cage, it has a particularly high load capacity by the maximum number of rolling elements and supports high radial and also high axial loads In addition, there is a reduction of friction due to the open space between the roller sets which is filled with grease, relatively high and also permanent axial loads can thus be supported.
with inner ring, can be used if the surface of the shaft is not suitable as a raceway.
with axial guidance,the axial guidance is carried out by the central rib and the rolling elements.
