1) Material - Outer races, inner races and rollers are made from
52100 steel and hardened to Rockwell hardness 60-64 RC. These
bearings are equipped with stamped steel cages.
2) Lubrication -
Outer races have an external centered oil groove and one oil hole.
Inner races have an internal centered oil groove and one oil
hole.
3) For applications where the bearing is run directly on
the shaft, no inner race is required. The shaft hardness should be
60 Rockwell C scale.
實體套圈滾針軸承是一種斷面高度小承載能力高的軸承。由于外圈硬度高，即使是輕合金軸承座，也可以應用自如。這種軸承可提供公制及英制二個系列的產品，各系列都有帶保持架、滿針型及密封型三種結構。此外，實體套圈滾針軸承可分帶內圈或不帶內圈二種，不帶內圈者以心軸作為滾道面，使體積變得更小。 |
