SKF 61840 1 Row Ball Bearing - 200 mm ID, 250 mm OD

This SKF deep-groove bearing maintains quiet operation in applications that demand high rotational speeds. It features precision rolling elements and specially-designed raceway grinding equipment for ultra-low noise and maximum efficiency. A slim design makes it lightweight and compact, while maintaining reliability. The bearing is made from steel, which makes it strong and offers good resistance to moisture, grease and chemicals, so it won't easily corrode in the presence of these substances.

• Open end, cylindrical bore type

• Robotics

This bearing from SKF is an open-end type, so it's not sealed. It's most effectively used in components where you're unlikely to find airborne contaminants, such as in car gearboxes and transmissions.

Bearings with cylindrical bores are either press-fitted or shrink-fitted. Press-fitted bearings are pressed onto a shaft, while shrink-fitted bearings are heated to expand their diameter before being applied to a shaft.
