Machined type needle roller bearings without inner ring

Jehlová ložiska bez vnitřního kroužku
In the case of needle bearings, the shaft surface or the hole surface of the house can be used as the raceway. In these cases, their accuracy and roughness are important because they affect bearing life, noise and running accuracy. If the shaft surface meets the raceway surface requirements (hardening and precision grinding), a needle bearing without an inner ring may be used.
These bearings are characterised by their high load capacity even for high-speed applications. They meet the requirement for lightweight construction, transmitting high performance in a small space.
Bearing series: NK .../.., RNA ...., RNAO..., NKS..., TAF..., BR..., GBR...
