Heavy Duty Pillow Block Bearings
Heavy Duty Pillow Block Plain Bearings
To facilitate mounting, the ends of pins or shafts and the edges of housing bores for spherical plain bearings should have a lead chamfer of 10° to 20°. The bearings can be more easily pressed into position and there is little risk of damage to the mating surfaces being caused by skewing of the bearing.
When mounting spherical plain bearings with a fractured or two-part outer ring, it is essential that the joint should be positioned at 90? to the main load direction; otherwise the service life will be shortened, particularly under heavy loads. Also, the bearing’s lubrication holes will be placed in the load zone, allowing lubricant distribution where it is needed most.
Bearing rings should NEVER be hammered into place. Only apply mounting forces onto the ring that is being mounted (i.e. force on outer ring if being pressed into a housing, force on inner ring if pressed onto a shaft). NEVER apply mounting forces though the bearing’s sliding surfaces, this will damage the bearing and will severely decrease its service life. In the event that the bearing has a press fit on both the inner and outer rings, a special tool should be made to allow pressing of both components simultaneously.
Other ways of mounting with the facilitation of heat or refrigeration, or with the use of adhesives may be possible also, please contact AST Engineering for further assistance.
The heavy duty block bearing can be easily and effectively self-aligning the mounting error, and can be easily installed on various industrial shafts, which is particularly useful in the frame of the equipment. The product range of the bearing housing is very wide. There are vertical seats, various flanged seats, keyed seat, round seat, etc. The material is gray cast iron seat, ductile iron seat, steel stamping seat and stainless steel seat. And plastic seats, etc.

The Mounted spherical bearing is composed of outer spherical bearing and bearing seat. It does not need to be designed separately when used. It has small size and simple structure. It can be directly bolted to the design part of the mainframe. It is easy to use
Simple and practical, the bearing seat has a monolithic structure, large bearing capacity and good rigidity. The bearing and the bearing seat can be interchanged, that is, the same bearing seat can be installed with different types of bearings; similarly, the same type of bearing can be selected for various types of bearing housings
Automatically adjustable: The spherical bearing with seat can work under different shafts of the two bearing seats, and the maximum automatic adjustment angle can reach 2°
Attachment assisted, the inner diameter of the outer spherical bearing with a "+" tolerance, forming a clearance fit with the shaft, through the top wire, eccentric sleeve or adapter sleeve on the inner ring, the bearing is fixed on the shaft, reducing the shaft The accuracy requirements make it extremely convenient to install or replace bearings
The working environment is small. The spherical bearing with seat is generally pre-filled with grease. It is double-layer or three-lip seal. It is suitable for use in dust, muddy water and corrosive media. It is good for the main machine
Accuracy advantages, the spherical bearing with seat has good rotation accuracy
