BALL BEARINGS

GRW: Superior quality. Perfection in performance.

We achieve the highest quality products and services through continuous research and development and improvement in all operational processes. Our engineers develop ball bearings and complete assemblies for highly demanding applications such as medical and dental technology, vacuum and aerospace instrumentation. All of our products, whether high precision or standard ball bearings, are manufactured using state-of-the-art precision production equipment. Whatever your bearing need, when you’re looking for an answer, GRW is your best resource for lasting solutions in precision bearings.

Radial deep-groove ball bearings

Single-row deep-groove ball bearings are suitable for use at both low and high speeds. They absorb radial and axial forces. They cannot be dismantled. (Electric motors, fans, encoders, flowmeters, etc.)

Single row deep-groove ball bearings consist of

• An inner and an outer ring
• A set of balls with cage and (usually) a layer of load-bearing lubricant
• Optional covers or seals.

Application of a suitable lubricant will extend the service life of these ball bearings. GRW offers a range of over 400 different lubricants (oils and greases) from which we can select, based solely on your needs.

Materials and designs

In addition to our chromimum steel,for 100Cr6 bearing rings, we also offer the stainless martensitic anti-friction SS (X65Cr13) and SV (X30CrMoN15-1) roller bearing steels.   In our hybrid designs the balls are made of ceramic materials. We offer a standard two-part steel ribbon-type cage. Plastic cages in different materials and designs are also available. Non-slip covers are made of corrosion-resistant sheet steel, reinforced Perbunan (nitrile rubber) or fluorine rubber (FKM). Depending upon the design of the bearing, the sealing discs next to the inner ring are made from Teflon-coated glass fiber fabric, reinforced Perbunan (nitrile rubber) or fluorine rubber (FKM).  Over 300 different lubricants can be configured based on application requirements.

Standard range and special formats
Our standard version deep-groove ball bearings are classified according to ISO or AFBMA. However, when special tolerances and special versions are required in lieu of a standard version, we can accommodate your specifications.
