Product Description

 

Product Description

 

 

Crossed Roller Bearings:

 

Cross Roller Bearings are a type of roller bearing with high rotation accuracy capable of bearing loads in every direction. Because it has orthogonally arranged cylindrical rollers, it can bear loads in every direction. This lets one crossed roller bearing replace more than one ball bearing, thus saving the space required by ball bearings, lowering the associated material costs.

• ▪ Widely used in machine tools, industrial robots and medical equipment because of their high rotational accuracy.
• ▪ Roller guide options include a cage or separator as well as a full complement design. Both the cage and separator styles offer a small coefficient of friction for high-speed rotation. Full complement bearings handle heavy loads at low speeds.
• ▪  Sealed and open designs are available. Sealed bearings incorporate synthetic rubber seals to protect against dust, dirt and grease.
