Radial Deep Groove Bearings

Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.

The C-HIP Ceramic Hybrid are similar to our Ceramic Hybrid series, but these C-HIP bearings utilize ceramic balls that are made with by Hot Isostatic Pressing (HIP). These ceramic balls have an even greater density and hardness than a standard ceramic ball. Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel.

Chrome Steel 52100 Series Radial Bearings contain chromium and, due to thorough hardening, have excellent surface quality and high load capability. 52100 Chrome Steel Radial Bearings are a universal material for many applications. Chrome Steel is magentic.

Stainless Steel 440C Series Radial Bearings contain a martensitic-type stainless steel used extensively in bearing applications that require hardness, dimensional stability, corrosion resistance and toughness. Stainless Steel 440C is resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and food stuffs. Stainless Steel does contain some carbon so it is still slightly magnetic and may eventually rust.

Ceramic Hybrid Special Stainless Saltwater Radial Bearings. The new Special Stainless Saltwater Series AKA Boca Salt Series is a new type of bearing that utilizes a special form of stainless steel, different than the traditional 440C Stainless that is commonly used in saltwater/corrosive applications. This special stainless steel lasts 2-3 times longer than traditional stainless steel. These bearings have SI3N4 ceramic balls with special stainless steel races, shields and retainers. The Metal shielded bearings are non-contact which allows the bearing to spin freely without any excess drag. Ceramic will never corrode, has less rolling resistance and is lighter than steel. As a result ceramic bearings last longer and achieve higher RPMs.

Bearings with a flange on the outer ring simplify axial location. The housing for such bearings can consist of a through-hole of uniform diameter, but the entry face of the housing (which may be either the outer or inner face) must be machined truly normal to the hole axis. However such flanges can be expensive to manufacture.

The GRW Bearing Series is a line of ultra-high precision bearings for the most demanding applications. Manufactured in Germany, these bearings come in ABEC #7 and ABEC #9 precision. We offer ceramic hybrid as well as standard steel versions of this series. These bearings can be found in the most demanding applications such as aerospace, jet turbines, flow meters, and many others. Where the highest precision bearing is needed, we have you covered with the GRW Series. 

To ensure a long life for flow meters it is crucial that the meter has been installed with the proper bearing material depending on the fluid lubricity and operating temperature. Many turbine meter installers prefer ceramic bearings for their superior design and durability. Ceramic bearings are a substantial upgrade over traditional steel bearings for many turbine flow meter environments. Ceramic is a non-porous, glass like surface so it is virtually frictionless and therefore needs very little or no lubrication to operate. Ceramic is also ideal for extremely high or low temperature applications with ranges of -100°C to +900°C (-148°F to +1652°F.)
