DEEP GROOVE BALL BEARINGS

Bearing Features

Deep groove ball bearings have grooved raceways on the inner and outer rings, enabling them to sustain moderate axial loads in both directions and radial loads. Balls are separated by steel cages, permitting high-speed operation. Double row angular contact bearings are designed to accommodate axial and radial loads simultaneously. Balls are separated by high-speed polyimide cages.

Most bearings are prelubricated with Mobil Polyrex EM grease or Chevron SRI-2 for excellent lubrication to 350°F. Sealed and shielded bearings are lubricated for life.

Bearing Steel

Standard bearings utilize bearing quality 52100 through hardened steel. Stainless steel units utilize bearing quality AISI 440C stainless steel, providing corrosion resistance, hardness and strength.

Configurations

ABT radial ball bearings are manufactured as either sealed (2RS), shielded (ZZ) or open. Many bearings can also be supplied with snap rings (NR).

Sealed (2RS) bearings feature contact lip seals that provide excellent protection from liquids and contamination. However, seal rubbing can result in friction (drag) and produce heat, which could be a concern in high-speed applications. Shielded (ZZ) bearings have non-contact steel shields that do not protect against liquids but add no friction or heat build-up during operation.

Open bearings are supplied with a coating of light oil and are used in oil bath and oil mist environments. Snap ring (NR) bearings are supplied with snap ring grooves and snap rings installed on the OD. (Not all bearings are available as NR.)

Packaging Bearings are bulk-packaged and wrapped in rolls or packed in plastic tubes for protection in shipping and handling. Individual and customized packaging is available upon request.
