Deep Groove Ball Bearings Available as Single or Double Row type. Features include open, one or two shields, one or two seals and locating snap ring. Also available as Extra small, Miniature and Maximum types. The most popular type of bearing, it supports both radial load and a certain degree of axial load in both directions simultaneously.
Cylindrical Roller Bearings Available as Single, Double or Four Row. Features include Thrust Collars, parallel or tapered bore and lubrication holes and grooves. These feature high radial load capacity as the rollers and raceway are in linear contact. Suitable for heavy radial and impact loading.
Tapered Roller Bearings Available as Single or Double row, and in Metric and Inch sizes. Can be produced as either TDO (one double cup and two single row cones) and TDI (one double cone and two single row cups) Designed so that cups, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. This type is suitable for applications involving heavy or impact loading.
Spherical Roller Bearings This type features a large load rating capacity and self-aligning capability. Cylindrical and Tapered bore are available, as are Adapter assemblies and Withdrawal sleeves. Suitable for low or medium speed applications which involve heavy or impact loading.
Needle Roller Bearings Designed to be small in sectional height for products with space constraints. Available as Drawn Cup, Machined Ring, Thrust, Stud type (Cam followers), Yoke type (roller followers) and as Miniature One way Clutches. Compact, highly rigid and superior in load carrying performance. Excellent for carrying oscillating loads. Now greatly used as miniature clutches in office equipment.
Angular Contact Ball Bearings Available as Single or Double row, Matched Pair and Four Point Contact. Designed for high accuracy good high-speed performance. Carries a combined load, axial and radial.
Ball Bearing Units Produced as units consisting of pre~lubricated ball bearings and housings of various shapes. Types available include Pillow block, Flanged, Take-up, Cartridge, Light Duty, 'Clean' Series (light alloy), Stainless and Pressed Steel units.
Good at aligning themselves using the spherical fitting surface between the bearing and the housing. Provide excellent load resistance.
