Stainless Steel Bearings

Stainless Steel Bearings


Boca Bearings offers many products in standard bearing 440C Stainless Steel as well as in other specialty Stainless options, like the 300 series, and special Q-SALT series. Stainless Steel offers greater corrosion resistance than standard steel and as a result stainless steel bearings tend to last longer in many enviornments. 

Typically a product that begins with S, S-, or SS- denotes stainless steel.

Extensive Stainless Steel offerings can be found among many different product groups at Boca Bearings.



Stainless Steel Bearing Styles and Sizes



Stainless steel bearings are available in variety of sizes and styles:



Stainless Steel Radial Bearings

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 material. Stainless Steel does contain some carbon so it is still slightly magnetic and may eventually rust...

Special Stainless Steel Bearings

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...

Mounted Unit Bearings

Flange mounted bearings are used when a shaft axis is perpendicular to the bearing mounting surface. Available in 2, 3, or 4-hole configurations, flange mounted bearings provide a method of accurate mounting fits and load support. 2-bolt flanged bearings have a diamond shaped flange with 2 mounting holes. Most 3-bolt flanged bearings have a circular mounting flange with three, equally spaced mounting holes...

Insert Bearings

Insert bearings and wide inner ring bearings are used for mounting on shafts without the need for shoulders or adapters. The bearing is locked in place through setscrews or a locking collar. UC Style Insert Bearings have an inner ring that extends on both sides of the bearing and SB Style Insert Bearings extend on one side. Both designs however are ...

Needle Bearings

Needle bearings use a roller-style rolling element to reduce friction of a rotating surface. Needle Bearings have a high load carrying capacity with a very small cross-section height. They are available with or without an inner ring. The needle rollers are guided parallel to the axis using a cage retainer, thrust bearings can also be supplied with no retainer, which is referred to as a full complement of rollers. The Boca Bearing Company specializes in miniature needle bearings.

One Way Clutch Bearings

One Way Clutch bearings or Sprag style bearings are constructed from a drawn cup with needle roller clutches and have a small radial section height. They are often called One Way bearings, Anti-Reverse bearings, or Clutch bearings. The units are compact, lightweight, and operate directly on a shaft; they are also suitable for transmitting high torque. Boca Bearings offers Standard and Stainless Steel One Way Clutch bearings as well as OWC style One Way bearings in standard and stainless steel, EWC Hex One Way bearings, and CSK Sprag Type one way bearings available with availabe keyway options for higher torque capabilities.

Thrust Bearings

Thrust bearings are designed for side or axial loads, and cannot handle much radial load at all. The rolling element in a thrust bearing can be a ball, needle or roller. Thrust bearings come in both metric and inch sizes. Dimensions to consider when searching are the bore, the outside diameter and the overall width. Operating specifications to consider when searching for thrust bearings are rated speed, static axial load, and dynamic axial load. RPM for a bearing running in oil is going to be higher than one running in grease. The static axial load is the maximum axial load a bearing can withstand while stationary without suffering permanent damage...
