INA needle bearing with ribs minimum radial load & speeds

INA needle roller bearings with ribs minimum radial load

In order to ensure operation without slippage, the bearings must be subjected to a minimum load Fr min in a radial direction. This applies in particular to high speed bearings since, if the radial load is insufficient or not present, damaging sliding motion may occur between the rolling elements and raceways. In continuous operation, a minimum radial load of the order of Cr/P < 50 is necessary.

Speeds: The limiting speeds nG given in the dimension tables for RNA49..-RSR (2RSR) and NA49..-RSR (2RSR) are valid for grease lubrication.
