Oscillating bearing , or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications.
Size range: Available from 12.7 mm - 600 mm (0.500 in. to 23.622 in.) bore
Rings manufactured from hardened steel help deliver consistent, reliable performance.
Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces.
Simplified housing and shaft designs reduce installation time.
A-frames, dump cylinders, front and rear struts, and steering cylinders for mining trucks
Equalizer track bars, lift and tilt cylinders, push blades, trunnion balls and ripper blades for bulldozers
Articulated joint upper and lower steering cylinders and boom and bucket cylinders for wheel loaders
Stick and bucket cylinders for hydraulic excavators
Additional applications for space shuttles, heavy movable structures and miscellaneous vehicles
Ball Bearing Housed Unit, which are usually referred to as insert bearings, are basically sealed deep groove ball bearings in the 62 and 63 series with a convex sphered outer surface . These insert bearings are manufactured in a number of different series and sizes and are available with standard inner ring or an inner ring that is extended on one or both sides.
The various bearing series differ in the way the bearing is located onto the shaft. The most common methods use any one of the following:
– Grub screw locking
– Eccentric collar locking .
– Adapter sleeve locking
– Interference fit
This type of bearing is separable. As their rollers linearly come into contact with inner ring and orter ring with less coefficient of friction, these bearings have very good capacity of radial load, suitable for electric metors, automobiles, transmission shafts, gear shafts and so on. Double row cylimdrical roller bearings are good at the spindles of machine tools.

Needle roller bearing is roller bearing with cylindrical roller, compared with its diameter, the roller is slender and long. This roller is called needle roller. Althorgh it has smaller cross section, the bearing still has higher load ability. Therefore, it’s specialized in the occasion which is restricted radial space.

Feature of Spherical Roller Bearing
Spherical roller bearings are designed to manage high radial loads even when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present. Spherical rollers are put between the spherical raceway on the outer ring and the two grooves on the inner ring for bearings. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement, the bearings are self-aligned and automatically adjust the bending of the shaft and housing and the eccentricity. Spherical rollers bearing can carry radial load and axial load in double directions. The especial radial load carrying capability of spherical rollers bearing makes the bearings suitable for heavy load and shock load carrying.Spherical roller bearings Cage type: CA,CC,C, MB

Four-point angular contact ball bearings have a contact angle of 30°and inner rings which are separated in half. When the inner and outer rings receive a radial load the ball bearings contact the inner and outer rings at four points. This construction enables a single bearing to accommodate axial loads from either direction, or when generally under a simple axial load or heavy axial load, the bearing functions in reliance on two contact points like ordinary bearings.
1. To accommodate axial loads from either direction;
2. Can also act with two contact points under simple or heavy axial load
