Product introduction
316977C Cylindrical roller bearings are separable bearings, which are very convenient to install and disassemble. Cylindrical roller bearings can withstand large radial loads and are suitable for use in high-speed operating situations.
(Good quality looking ZH, good price looking ZH)
This type of bearing allows the Angle error (inclination) between the inner ring axis and the outer ring axis to be very small, only 2 '~ 4'. Therefore, the machining accuracy of the shaft and bearing seat is relatively high. Otherwise,
it is easy to have uneven load or stress concentration in the raceway contact part. However, the stress concentration can be reduced by modifying the roller or raceway contact busbar.
