NUTR .. design support rollers

NUTR .. design support rollers (fig) are based on double row, full complement cylindrical roller bearings without an integral flange between the two roller sets. The outer ring has two integral flanges to axially guide the roller sets. A loose flange ring on both sides of the inner ring provides axial guidance for the outer ring via the roller sets. This enables NUTR .. design support rollers to accommodate relatively heavy axial loads that are induced when operating in an inclined or tilted position.

A sheet metal angle ring is pressed into the outer ring shoulder on both sides and forms an effective labyrinth seal. The angle rings extend over the flange rings, making the bearing nonseparable.

If heavy shock loads occur, support rollers with a reinforced outer ring should be used. These are identified by a four- or five-digit number instead of a two-digit number in the bearing designation, e.g. NUTR 50110 .
