PWKR ...2RS design cam followers
PWKR ...2RS design cam followers (fig 1) are based on double row, full complement cylindrical roller bearings. The stud head and a pressed-on flange ring guide the outer ring axially via the roller sets. This enables PWKR ...2RS design cam followers to accommodate relatively heavy constant axial loads that are induced when operating in an inclined or tilted position.
PWKR ...2RS design cam followers are supplied with a contact seal made of oil and wear-resistant acrylonitrile-butadiene rubber (NBR) on both sides. The seals are integral with the sheet metal angle rings and press against the flange ring and the stud head. The angle rings are pressed into the outer ring shoulder.
PWKR ...2RS design cam followers have a recessed hexagon at both ends of the stud that enables the cam follower to be held in place by a hexagonal key (Allen wrench) during mounting. In the center of each hexagon is a relubrication hole for a press-in grease fitting or an adapter from a central lubrication system. For additional information, refer to the section Accessories.
