Rolling element

Cylindrical rollers are the basic elements of cylindrical roller bearings. They are made from through hardened rolling bearing steel in accordance with ISO 683-17 and have a hardness of at least 670 HV. The dimensions and tolerances conform to DIN 5 402-1.
Depending on the application, the profile has either a standard or logarithmic curve. The profile, in conjunction with the profiling of the raceways, prevents edge stresses
Needle rollers are the basic elements of needle roller bearings. They are made from through hardened rolling bearing steel 100Cr6 to DIN 17 230, have a hardness of at least 670 HV and conform to DIN 5 402-3/ISO 3 096-B with flat end faces.
The ends of the needle rollers are profiled. Due to this profiling, the outside surfaces have a curved transition to the end faces. This reduces the edge stresses at the ends of the rolling elements.
Needle rollers are available in the diameter range from 1 mm to 6 mm, in lengths from 2 mm to 43,8 mm and in grade G2
