The needle and cage assemblies are single or double row units consisting of retainers and needle rolls.
because the radial cross section is not larger than the needle diameter, the needle and cage assemblies allow for bearing layout through very small radial design envelopes. It has very high load capacity, is suitable for high speed, and is especially easy to install.
if the geometric accuracy of the groove plate is very high, the bearing layout can achieve a high skew accuracy.
pin type and tolerances of shaft and bearing seat can affect radial internal clearance.
The roller and cage assemblies on the shaft and in the bearing housings of the require hardened and milled grooved plates. |
