Stud type track rollers are based on roller bearings. They absorb radial loads and axial loads. Axial loads arise from alignment errors, skewed running or short-term tipping moments and impacts. The permissible level of the axial load is dependent on the profiling of the outer ring and the rolling elements used: needle rollers, cylindrical rollers, spherical rollers or tapered rollers. They exist with or without axial guidance, open or sealed. They are fitted onto shafts.
- Needle roller stud type track rollers, with or without axial guidance open or sealed
- Cylindrical roller stud type track rollers, with or without axial guidance open or sealed
- Coated stud type track rollers
- Stud type track rollers made from special materials – e.g. rust-resistant steel
- Sealed high-temperature spherical roller stud type track rollers – e.g. for kiln cars
- DRK – stud type track rollers
- High precision roll stand back-up rollers
