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.
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
