AST Bearings is proud to be the exclusive national stocking distributor for GRW Bearings a world recognized manufacturer of high precision bearings from Germany. GRW Bearings' products have been revolving all around the world for more than 50 years providing the highest accuracy and absolute reliability.
The company headquarters in Wurzburg, Germany houses, the administration and production facilities and the modern production facilities with more than 350 employees working on the development and manufacturing of the high precision ball bearings.
GRW Bearings offers short development times and modern production facilities to fulfill all requirements in precision and function. Together with AST Bearings' added value services and cutting edge bearing technology, you receive a guaranteed economical solution in design and application.
Specializing in the manufacturing of miniature deep groove ball bearings made from through hardened chrome and stainless steel with standardized dimensions and variations. Some variations are separable angular contact, spindle or duplex and hybrid ball bearings.
Additionally, beyond the DIN and ISO standards GRW Bearings has defined their own standards with higher requirements. That means that you receive ball bearings, which have been developed and manufactured to correspond to your exact specifications.
GRW Bearings' results of more than 50 years experience guarantees the precision and finish of their miniature ball bearings that can only be seen with the aid of a magnifying glass. However these features are even more apparent when the bearings are fitted into specialized applications such as, instruments in the microelectronics, aviation and aerospace engineering, instrument and dental fields because of their accuracy, reliability and smooth performance.
GRW Bearings produces 20 million miniature and small ball bearings with a bore sizes ranging from 1 to 17 millimeters and an outer diameter of 3 to 40 millimeters. These bearings offer the highest levels of precision and functionality that is needed in a confined space. These bearings are mass-produced for standard ranges in electric motors, ventilators and office machinery.
AST also supplies GRW Bearings' most advanced material the alloy SV30. This innovative material dramatically improves the running characteristic of the miniature bearing. It uses the constituent's nitrogen, carbon, chrome and molybdenum in a new type of alloy composition. SV30 is distinguished by its improved alternating bending strength, elongation at rupture, high temperature resistance, toughness and chemical resistance. By these criteria, GRW Bearings' SV30 is well ahead of all ball-bearing steels used in production to date. The SV30 material offers considerable advantages for the miniature ball bearing such as:
- Higher resistance to corrosion
- Longer life duration
- Better running behavior at high temperatures, in contaminative environments, with reduced lubrication or dry running
GRW Bearings' product lines offer High-Precision solutions without the concerns of quality and craftsmanship.
Examples of applications:
- Medicine
- Surgical Equipment
- Blood Pumps
- Dental Turbines
- Aeronautical and Space Industry
