Product Details:

The internal design of track rollers is the same as in single row or Double-rowAngular Contact Ball Bearings.The units can carry axial loads in both directions and, due to the thickness of the outer ring,large radial loads.

The standard product are produced from high quality bearing steel, with a hardness of 58 to62 HRC. Some types are also available in stainless steel (440C) with hardness 58 HRC.The track rollers contained in this catalogue are produced with standard tolerances (ISO 492)and standard clearance (CN).The track rollers are produced in two distinct families. Cylindrical or crowned outer ring andprofiled outer ring.NIKO1. Bearing materials

These track rollers are available in single and double row design. They are available withstraight cylindrical OD or crowned profile OD. The crowned OD is used to reduce the edgestresses caused by possible misalignment errors. The cylindrical OD can provide increasedsupport due to the longer contact profile.There products are used typically on flat surfaces.

The outer profile can have three different designs;-

Track rollers with gothic arch groove - type LFR- The track rollers RV have a groove machined in the outer ring. The groove is V shaped with an included angle of 120 degrees. These units are predominantly used on shafts with diameters from 7 to 20 MM. The contact between track roller and shafts is on two points. In special cases, the units can run on profiled ways. The units are supplied with non contact shields.

Track rollers with V shaped groove - type RV- The track rollers RV have a groove machined in the outer ring. The groove is V shapedwith an included angle of 120 degrees. These units are predominantly used on shafts with diameters from 7 to 20 MM. The contact between track roller and shafts is on two points. In special cases, the units can run on profiled ways. The units are supplied with non contact shields.
Track rollers with W profile - type RM The track rollers series RM have grooves machined in the outer ring of the unit with anincluded angle of 90 degree. They have been engineered to run on profiled steel elements that have identical shape. They can run on either the internal or the external surfaces of the outer ring. They are available with either non-contacting shields ZZ or contact seals 2RS.
Some of the most common applications are:-transfer rolls-idler rollers-Support rollers-Straightening rolls

Product Details:

Track rollers LFR are double row angular contact ball bearings comprising an outer ring with a gothic arch profile, an inner ring and two ball and cage assemblies with plastic cages. The inner ring and outer ring are made from rolling bearing steel
The special outer ring gives two point contact in the contact zone with the raceway. The contact angle α is a maximum of 30°. The bearings can support axial forces from both directions as well as radial forces
