ZKLF Series Bearings

 

ZKLF Series Bearings Introduction:

ZKLF series bearings are double direction thrust angular contact ball bearings.
Double driection thrust angular contact ball bearings are specially designed high-precision bearings for machine tool spindles, which can bear axial loads in two directions.
ZKLF series bearings have 2 sealing type, 2RS and 2Z.This type bearings are widely used in many applications, for example,
Tape cutting machine, decoction piece machinery, reverse dialysis equipment, vibration testing machine, high pressure reactor, auxiliary plastic machine, manual sandblasting machine, electrolytic cell, laminating machine, fertilizing machine, cylindrical gear reducer, excavator, and so on.
