Features of Super Slim Type Crossed Roller Bearing CRBT
load rating C
load rating C0
g
The world's thinnest roller type! Very low cross sectional height of 5.5 mm.
The cross sectional height is reduced by 69% in comparison with CRBS, which was the thinnest before (bearing bore diameter 50 mm). The width is also as small as 5 mm and the cross sectional area is reduced by 43% in comparison with conventional products.
Significant weight saving by 38% in comparison with conventional types was realizedWeight reduction is thoroughly pursued. The mass ratio is 0.38 and significant weight saving was realized in comparison with conventional slim type CRBS (bearing bore diameter 50 mm).
Structure and Features
1. Ultra-Slim and Ultra-Small!
These Crossed Roller Bearings are ultra-slim and small with a 10mm bearing bore, 21mm outside diameter, and 5mm bearing width.
2. High Rigidity and a Compact Size!
In Crossed Roller Bearings, the orthogonal array of rollers reduces the cross sectional area of rear-mounted 45° contact angle single-row roller bearings or ball bearings by half, creating a compact structure.
Even though they are more compact, the rigidity is 3 to 4 times greater than double-row angular contact ball bearings.
What are Crossed Roller Bearings?
Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings. The orthogonal array of the rollers allows the bearing to handle complex loads simultaneously from any direction, which makes assembly possible without needing to worry about load direction.
Compact Hand Robot
Crossed Roller Bearings feature high rotational accuracy and high rigidity which minimizes deflection, making them ideal for the swivel parts of hand robots, that require accurate positioning motion.
Compact Surveillance Camera
Crossed Roller Bearings can receive complex loads from various directions, making them ideal bearings for supporting surveillance cameras which are in constant 24-hour operation.
