Ball Bearings:Ball Bearings are available in many different types to meet a variety of application requirements.
Deep Groove Single Row-Most common of ball bearings and are available in inch and metric sizes. They are manufactured Open (no seals), Rubber Seals, or Metal Shields and are available with a retaining ring. Sealed ball bearings come prelubed with grease and are temperature rated from -22*F to +250*F.
Double Row-Available as self-aligning and angular contact. Like Single Row, they are available in inch and metric sizes and are manufactured Open, Rubber Seals or Metal Shields. They also are available with a retaining ring.
Tapered Roller Bearings:Tapered Roller Bearings are used not only in the automotive industry, but also in the machine tool industry. The bearing consists of 2 pieces: a cup (outside race) and a cone (bearing-cage and rollers). Due to the design of the bearing, it carries a larger/higher load rating than the traditional ball bearing. They are available in inch and metric sizes.
Spherical Roller Bearings:Spherical Roller Bearings consist of 2 rows of rollers with a raceway in the outer ring. Because of their design, they are self-aligning and suitable for misalignment applications.
Thrust Ball Bearings:Thrust Ball Bearings are available in either single or double direction. They consist of a row of balls within a cage and run between 2 grooved washers. Thrust bearings do not handle any misalignment but do handle axial loads.
Needle Bearings:Needle Bearings are used to reduce friction and support radial loads. They are used in a variety of different applications. They are available in inch and metric sizes and also as full complement and caged styles.
Rod Ends:Rod End Bearings are known for their unique swivel ball with an opening for a bolt. They are available in inch and metric sizes. They also are available in male (threading on the outside) or female (threading on the inside) and left hand or right hand threading.
Cam Followers:Cam Followers are available in many different options. You have Full Complement, Caged, Needle Roller, Double Row Cylindrical and Bushing Type. They also come as a Standard Stud, Heavy Duty Stud and Yoke Type. The outside diameters are available in Crowned (helps prevent corner loads) and Cylindrical (helps misalignment in corner loading). They are used in Track/Load support and track guides. Cam Followers are available in metric and inch sizes.
Mounted Bearings:Mounted Bearings come in a variety of different sizes and shapes to fit your application. Most are available from ½” to 4” bores. The most common are Pillow Block, 2 Bolt Flange and 4 Bolt Flange bearings. They also have 3 Bolt Flange, 3 Bolt Bracket, Tapped Base, Take Up Units and Piloted Bearings. The inserts are made up of ball bearings. The majority of these units are available in Standard Duty and Medium Duty and housings are made out of Cast Iron to withstand shock/vibration and load.
Mounted Bearing Housings are also offered in Corrosion Resistant. These bearings are most used in food manufacturing and where OSHA deems mandatory. Housings are offered in Stainless Steel, Thermoplastic and Nickel Plated. Inserts are available in Stainless Steel, Hard Chrome Coated and Black Oxide.
If you have shock/vibration, load or speed issues, typically, Pillow Blocks and 2/4 Bolt Flange units are available with tapered roller bearings or spherical roller bearings. Commonly these units are in a “beefier” housing to withstand your application issues. If you have shaft expansion due to temperature differentials, there are expansion units as well.
If you are not sure which mounted bearing you need or you need to replace your existing unit, give Industrial Power Transmission a call. We will be happy to assist you with replacement or engineering the best bearing for your needs.
