ZKLDF180 Axial Angular Contact Ball Bearing Series 180X280X43mm

Product Description

ZKLDF180 axial angular contact ball bearing series are designed with 60°contact angle and two rows of ball rollers, which can support radial load, double axial loads and tilting moments.Due to the special design with copper cages, the bearings have higher strength and lower friction torque. So this kind of bearings is especially used to the situation with super speed, long time running, high stiffness and high precision(HONBbearing02).

Bearing characteristics:

1. High precision: P4 precision, P2 precision

2. Basic load rating(Axial):Ca=85KN Coa=440KN

3. Limiting speed(Grease): 1700r/min

4. Bearing friction torque: 3Nm

5. Mass:8kg
