CRBTF Structure and Features

What are Crossed Roller Bearings?
Inner ring

IKO Crossed Roller Bearings are compact bearings with theirrollers alternately crossed at right angles to each otherbetween inner and outer rings. The orthogonal array of therollers allows a single bearing to handle complex loads
simultaneously from any direction, making mounting possible
without worrying about load direction.

Make your equipment more compact
with this super slim design!
Mounting Holed Type Super Slim Crossed Roller Bearings havean ultra-slim 5 mm bearing width, made possible thanks toIKO's technological expertise in miniature bearing production.

Inner ring· The shoulder height diameters (da and Da) which are related tomounting must meet the values shown in the dimension tables.

Easy bolt-on mounting eliminates complex
mounting procedures.

· When used with a housing, it is recommended to use a slightinterference fit adjusted to the actual measured dimensions of
the outer and inner ring. In addition, the depth of the housing
bore is recommended to be equal to or larger than the bearing
width.

Mounting Holed Type Super Slim Crossed Roller Bearings can bemounted directly to the mounting surface. No housing or pressure
plate required.
