Features of stud type track rollers
Curved track rollers are similar to yoke type track rollers in their internal structure, but have a combined inner ring bolt with a fixed rib. The inner ring pin can be made eccentric to set the stud type track roller against the raceway. They can support high radial loads as well as low axial loads and are suitable for cam controls, guides and conveyors. The relubrication can be optionally via a relubrication channel in the inner ring bolt.
Loads
The permissible radial load Fr zul of the stud type track roller must not be exceeded, since the resulting pressures in the contact can damage the mating track. About the values for the permissible radial load capacity of the cam rollers, our service team will be happy to provide information.
The axial load capacity of cylindrical roller bearings is influenced by the design, the lubricant used and the bearing tilting. Loaded ribs or thrust washers must be supported over the entire height. The Fa/Fr ratio should not exceed 0.4. An exclusive axial load without radial load is not permissible.
For the minimum radial load of needle roller bearings, a ratio of Fr/Cr>0.02 is recommended, especially at high speeds. The values for the dynamic load rating Cr can be found in our product data sheets.
Accuracies
The dimensional and running tolerances of the stud type track rollers normally correspond to the tolerance class P0 according to DIN 620-2.
Bearing Clearance
The stud type track rollers are designed in the standard with the bearing clearance class C2 according to DIN 620-4.

Sealing
Stud type track rollers are usually designed with angle rings and grinding sealing lip. Depending on the installation space, Sealing systems are also possible.
Materials
The stud type track rollers are made in your standard version from the material 1.3505 (100Cr6) and manufactured with a minimum hardness of 58 HRC. On request, corrosion protected versions are available.
