Compact size and high rigidity

Now Available! Super Slim Type Crossed Roller Bearings with a bore diameter of just 10mm and outside diameter of 21mm.
Smaller size can help reduce the size of your equipment.
■ CRBT105A Structure and Features■ What are Crossed Roller Bearings?

1. Ultra-Slim and Ultra-Small!

Roller

2. High Rigidity and a Compact Size!

Separator

In Crossed Roller Bearings, the orthogonal array of rollers reduces the crosssectional area of rear-mounted 45° contact angle single-row roller bearings orball bearings by half, creating a compact structure.
Even though they are more compact, the rigidity is 3 to 4 times greater thandouble-row angular contact ball bearings.

CRBT105A

Crossed Roller Bearings are compact bearings with their rollers
alternately crossed at right angles to each other between innerand outer rings. The orthogonal array of the rollers allows thebearing to handle complex loads simultaneously from any
direction, which makes assembly possible without needing toworry about load direction.

These Crossed Roller Bearings are ultra-slim and small with a 10mmbearing bore, 21mm outside diameter, and 5mm bearing width. The compact size ismade possible thanks to IKO's technological expertise in miniature bearing production.

Compact Surveillance Camera

Crossed Roller Bearings
feature high rotational
accuracy and high rigidity
which minimizes deflection,
making them ideal for theswivel parts of hand robots,that require accurate
positioning motion.

Crossed Roller Bearings
can receive complex loads
from various directions,making them ideal bearings
for supporting surveillancecameras which are in
constant 24-hour operation.
