ZKLN0832 Double Direction Axial Angular Contact Ball Bearing 8x32x20mm 60° Contact Precision Screw Support Bearing

1. Product Overview

ZKLN0832 is integrated double-direction axial angular contact ball bearing, overall dimension 8×32×20mm, standard 60° large contact angle design for lead screw support. Built-in double row ball structure bears bidirectional heavy axial loads with ultra-high rigidity. Available in 2Z metal shield or 2RS rubber sealed versions to block dust and moisture. Pre-installed light preload eliminates assembly matching work, low friction torque and tiny axial runout, widely matched for small CNC lead screws, precision testing equipment, miniature automation and medical rotary modules.
