SCR-E 

Outer circles are seperated into two parts, innner circle is one, it has stable inner ratation

Structure

In the crossed roller bearings , rollers are arranged directly between retainers at the v-grooved hole of 90-degree, so only one bearing can stand the whole weight from all directions such as axial loads and moment loads.
It has compact sized radial rates , slim type has more compact size , they are available for the precious curculation.
Friction is reduced by the retainer between the crossed rollers ,preventing the increasing the torgue and pausing.which garantee the stable rotation.
Seperated inner and outer structure allow to speed rotation.Wide contact of spacer type roller can stand the weight and reduce the scewing.
It can ratate smoothly with oily material, too.

Feature 

Eesy to handle
When assembled , Inner and outer circle are fixed , which make it easy to handle it.

Anti-skewing
Rollers are located on the right postion by spacer retainer , so it prevent the skew and get the stable rotation without frictio
