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.
实体套圈滚针轴承是一种断面高度小承载能力高的轴承。由于外圈硬度高，即使是轻合金轴承座，也可以应用自如。这种轴承可提供公制及英制二个系列的产品，各系列都有带保持架、满针型及密封型三种结构。此外，实体套圈滚针轴承可分带内圈或不带内圈二种，不带内圈者以心轴作为滚道面，使体积变得更小。
