RA9008 crossed roller bearings specification

size: 90*106*8mm

structrue: thin section crossed cylindrical roller bearings with separable outer ring and integrated inner ring.

sealing: sealed both sides

clearance: CC0/C0

precision: P5/P4

RA9008 crossed roller bearings have thin section(slim type), so it's suited for where space is limited, and inner ring running accuracy is required.

RA series crossed roller bearing provides high and stable running accuracy, suited for precision detecting instrument, robot joints, direct drive torque motor, high-precision turntable, etc.
