Barden/FAG is the pre-eminent leader in super precision ball bearing manufacturing in the world today. Barden super precision bearings excel in applications where bearings of lesser quality have failed. If superior accuracy, reliability of operation, long-life, high running speeds and low noise and vibration are requirements in your application. Barden products are predominantly radial, single row, super precision angular contact (separable and nonseparable) and deep groove ball bearings. Bearings are classified as either instrument or spindle bearings, and are made to exacting ABEC-7 or ABEC-9 routinely exceeds. Barden also sells ball screw support bearings, cylindrical roller bearings and double direction angular contact thrust ball bearings.

customized bearings

Barden super precision bearings are used wherever the need to meet critical tolerances, high speeds and performance under demanding operating conditions are required. Because they exceed ABEC tolerances, Barden bearings offer long life and reliable performance.


  • Machine Tool: Turning, Milling, Grinding, Machining Centers, Ball Screw Supports

  • Aircraft: Auxiliary Power Units, Blowers, Actuators, Gyros, Air Handling, Generators

  • Specialty Equipment: Vacuum Pumps, Textile Equipment, Food Processing, Robotics

  • Medical: X-ray, CAT Scanners, Dental Drills, Medical Centrifuges.

angular contact spindle bearings

Angular contact bearings have one ring shoulder partially or totally removed. This allows a larger ball complement than found in comparable deep groove bearings, hence a greater load capacity. Speed capability is also greater.


Angular contact bearings are assembled to a contact angle by varying the radial clearance. Spindle size Barden angular contact bearings have nominal contact angles of either 15° or 25°. The smaller angle delivers better radial capacity and rigidity, the larger angle is better for axial rigidity.


Separable and nonseparable types are available. In a separable bearing (B type), the cage holds the balls in place so that the outer ring assembly (with cage and balls) can be separated from the inner ring.

deep groove instrument bearings

Deep groove ball bearings have full shoulders on both sides of the raceways of the inner and outer rings. They can accept radial loads, thrust loads in either direction, or a combination of loads.

The design of deep groove bearings make them suitable for the addition of closures which help exclude contaminants and retain lubrication. Besides single deep groove bearings with closures, Barden also offers duplex pairs with seals or shields on the outboard faces.
