Stud type track rollers are similar in their construction to single and double row yoke type track rollers, except that the raceway is formed by a heavy-section roller stud with a fixing thread and lubrication hole.
In series KR, the radius of curvature is R = 500 mm. KR, KR..-PP have a cage, while the design KRV..-PP has a full complement needle roller set. The series NUKR and PWKR..-2RS have a full complement cylindrical roller set.
In KR, KR..-PP and KRV..-PP, axial guidance is provided by the contact flange and contact washers.KRE..-PP has a cage, NUKRE and PWKRE..-2RS have a full complement cylindrical roller set.
Stud type track rollers can be used at temperatures from –30 °C to +140 °C. In sealed bearings (suffix 2RS), the temperature range is restricted to between –30 °C and +120 °C.
