INA Stud Cam Follower KR47-PP-A 20 mm ID, 47 mm OD

INA from Schaeffler stud type track rollers are similar in their construction to single and double row yoke type track rollers. The raceway is formed by a heavy-section roller stud with a fixing thread and lubrication hole.;Due to the thick-walled outer ring with profiled outside surface and the rolling element set, they can support high radial loads as well as axial loads arising from slight misalignment and skewed running.;Stud type track rollers with a crowned outside surface are predominantly used since they are often inclined in relation to the mating track and edge stresses must be avoided.

• Lower operating costs;• Reduced maintenance due to improved lubrication;• Lower heat generation;• Less noise;• Lower Hertzian pressure;• Edge loading under tilting is lower;• Wear of the mating track is reduced;• Operating life of the mating track is extended;• KR..PP have a cage and plastic axial plain washers with formed seal lips on both sides;• NUKR have a full complement cylindrical roller set and labyrinth seals

Stud type track rollers are suitable for applications such as cam gears, bed ways and conveying equipment.

PP - Plastic axial plain washer with formed seal lip on both sides of the stud type track roller, giving a three-stage seal
