  • Custom Ball Bearing - we design custom ball bearings to reduce friction and support radial and axial loads.

  • Custom Caged Bearing - we're a preferred supplier of custom caged bearings for consumer products, and industrial applications.

  • Bearing Assembly - world leader in the development, prototyping, testing and manufacturing of custom bearings and bearing assemblies.

  • Ball & Roller Retainer - we have the b2b resources to engineer, prototype and manufacture the ball and roller retainer for your application.

  • Deep Groove Ball Bearing - single row deep groove ball bearings, double row deep groove ball bearings, heavy load ball bearings, miniature ball bearings.

  • Angular Contact Bearing - single row angular contact bearings, double row angular contact bearings.

  • Needle Bearings - custom needle bearings, drawn cup needle bearings, sealed drawn cup needle bearings, drawn cup full complement bearings, drawn cup roller clutches, clutch and bearing assemblies, radial needle bearings, long cylindrical roller and cage assemblies.

  • Thrust Bearing - single direction thrust bearings, double direction thrust bearings.

  • Plastic Bearing - plastic bearings are lighter in weight, corrosion-resistant, do not require lubrication and require less torque.

  • Roller and Pin - needle rollers, precision rollers, special end rollers, pins, shafts & dowels.

  • Plastic Conveyor Roller Bearings - all- plastic conveyor roller bearings for wash-down conveyor systems.

  • Custom Shaped Precision Rollers and Pins - for applications such as CV joints, locating pins, linear track rollers, bearings, and fractional motor shafts.

  • Glass Balls - glass balls are ideal for valves, bearings, and metering devices.

  • Non-metallic Ball - precision specialty balls are used in medical devices ranging from IV administration to surgical tools.

  • Precision Steel Balls - b2b manufacturer of precision steel balls in stainless steel, chrome steel, carbon steel; also tungsten carbide, and brass.

  • Stainless Steel Balls - stainless steel balls are highly resistant to rolling-contact fatigue. 440C stainless steel balls perform similarly to tool steels, and are ideal for use in antifriction bearings (rolling bearings).

  • Carbon Steel Balls - carbon steel balls provide reliable performance for inexpensive anti-friction bearings, steering columns, casters, conveyors and trolleys, roller skates, toys, and drawer slides.

  • Chrome Steel Balls - chrome steel balls are used in load-bearing applications, and in applications as diverse as check valves, food grinding systems, vibratory finishing, plating baths and linear motion components.

  • Tungsten Carbide Balls - tungsten carbide balls are the preferred choice for precision hydraulic valves, high-load bearings, inertial navigation systems, ball screws, linear bearings in slideways, gauging and checking instruments, and meters.

  • Brass Balls - brass balls are used in electrical devices, valves, petrochemical industry operations, and consumer products such as appliances.

  • Precision Glass Balls - soda lime glass balls, borosilicate 8330 glass balls.

  • Plastic Balls - zytel nylon balls, acetal balls, teflon balls, polypropylene balls, polystyrene balls, colored balls.

  • Industrial Coupling and Bearing Applications - ball & check valves, electrical switch contacts, small engine check valve, water dispensing control for poultry farms.
