Description:

NATR and NATV design support rollers

NATR design support rollers are fitted with a needle roller and cage assembly, while NATV design support rollers have a full complement of needle rollers. The outer rings of both bearing designs are guided axially by pressed-on flange rings. The narrow gap between the flange rings and the outer ring serves as a gap-type seal.

Both designs are also available with an axial sliding ring on both sides, identified by the designation suffix PPA. The axial sliding rings are made of polyamide 66. In the radial direction, the sliding ring forms a narrow labyrinth seal with the outer ring, to protect against coarse contaminants. In the axial direction, the sliding ring serves as a contact seal to reliably retain grease in the bearing. This improves the lubrication conditions in the bearing, keeps friction and heat low, and extends grease service life.

Support rollers with axial sliding rings can accommodate somewhat heavier axial loads than those without axial sliding rings. Axial loads are induced when operating in an inclined or tilted position.

NUTR .. A design support rollers

NUTR .. A design support rollers 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 .. A 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 non-separable.

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
