These bearings have no central rib on the inner ring and are therefore able to use longer barrel rollers.
這些軸承已沒有中央肋骨的內(nèi)圈，因此能夠使用較長每桶輥。
These bearings do not have a central rib on the inner ring so longer barrel rollers can be fitted; improved kinematics, optimised surfaces and even higher performance materials are possible.
這些軸承沒有內(nèi)圈上，使輥筒長可安裝中央肋骨，改進(jìn)運(yùn)動學(xué)，優(yōu)化的表麪，甚至更高性能的材料是可能的。
