Angular Contact
Bearings
GRW angular contact bearings (spindle bearings) are single-row bearings with either the inner or outer ring land reduced they can be subjected to both radial and axial (in one direction) loads.
For more information about GRW angular contact ball bearings please Contact Us.
Thin Section
Bearings
Thin-section bearings have very thin ring cross-sections or bearings with identical cross-sections, independent of their bore diameter. With a small footprint and low weight, GRW thin section bearings are characterised by low torque and high rigidity. For more information about GRW thin section bearings please Contact Us.
Deep Groove
Bearings
GRW deep groove ball bearings are suitable for use at both low speed with high sensitivity to torque and at very high speeds. They absorb radial and axial forces.
For more information about GRW single row deep groove ball bearings please Contact Us.
Hybrid / Full Ceramic
Bearings
GRW Hybrid and full ceramic bearings are built for extreme conditions, offering high corrosion resistance, high-temperature performance, and low wear, even with little or no lubrication. They are non-magnetic, electrically insulating, dimensionally stable, and—because ceramic balls are lighter than steel—last longer at high speeds. Contact Us.
Duplex
Bearings
GRW Duplex bearings provide precise radial and axial alignment, higher load capacity, and increased stiffness, helping reduce vibration and improve system reliability. Matched and preloaded pairs ensure controlled axial play, accurate fit, and longer bearing life when correctly installed.

Special Ball
Bearings
GRW offer a wide range of custom bearing solutions, including super, extra, & tandem duplex designs, as well as integrated shaft, housing, & precision component assemblies. We can provide compact designs, accurate preload control, and high load capability for applications ranging from standard to extreme conditions. Discuss your unique requirements.
Bearing with Profiled
Outer Rings
GRW profiled roller ball bearings are double-row angular contact bearings with specially shaped outer rings, designed to handle high radial loads & axial loads in both directions. Available in standard & custom designs, with options for different materials, seals, lubricants, & contact surface profiles to suit various applications & environments. Contact Us.
Ball Bearing
Assemblies
GRW ball bearing assemblies are high-precision, custom-built units assembled, tested, and packed in their R10,000 / Class 7 cleanroom to ensure consistent quality, accuracy, and performance, offering convenience, reduced play, and simplified ordering.
For more information please Contact Us.
Shims, Springs
and Clips
GRW shims, spring washers, and retaining rings are high-quality bearing accessories designed for precise axial control, reliable preloading, & secure bearing location, made from corrosion-resistant, burr-free materials to ensure accuracy, durability, & consistent performance.
