Track rollers

Features of track rollers

Rollers correspond in their internal structure to single- or double-row ball bearings and have a thick-walled, usually crowned outer ring. Optionally, they can be equipped with a combined inner ring bolt. The inner ring pin can be eccentric in order to position the stud type track roller against the raceway. They can support radial loads as well as axial loads and are suitable for cam controls, guideways and conveyor systems. The relubrication can be optionally via holes in the inner ring, or a relubrication channel in the inner ring bolt.

Loads

The permissible radial load of the track roller must not be exceeded, since the resulting pressures in contact can damage the mating track. About the values for the permissible radial load capacity of the track rollers, our service team will be happy to provide you with information.

For the minimum radial load of track rollers, a ratio of Fr/Cr>0.01 is recommended. The values for the dynamic load rating Cr can be found in our product data sheets.

Accuracies

The dimensional and running tolerances of the track rollers normally correspond to the tolerance class P0 according to DIN 620-2.

Bearing Clearance

The track rollers are designed in the standard with the bearing clearance class CN according to DIN 620-4.

Cages

Rollers can be created with Plastic or metal cages.

Materials

The 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.
