What are the Main Structures and Properties of Insert Ball Bearings?

The insert ball bearings is a combination of the outer ring of the outer diameter spherical surface and the deep groove ball bearing with a double-layer sealing device and a widened inner ring. The insert ball bearings is composed of various structural types of casting bearing housing or steel plate stamping seat. The bearing is the insert ball bearings with a seat. The bearing with a seat is compact in structure, light in quality and small in size. The bearing has good automatic self-alignment performance, allowing up to 10° earth at an angle. Compared with the self-aligning ball bearings equipped with a sectional housing in the corresponding size, it has greater bearing capacity and high ultimate speed, and excellent sealing performance. The machining accuracy of the mainframe-related parts is low. The inner hole of the bearing is usually matched with a gap. It can be directly fastened in any position with the top wire, eccentric sleeve or fastening sleeve and optical shaft, which is convenient to assemble and disassemble. It is especially suitable for the main engine with multiple support shafts, long shafts, and shafts with small stiffness and easy deformation. Such bearings are mostly used in mining, metallurgy, agriculture, chemical industry, conveying machinery, etc.

The main structural types are:

1. There are two kinds of insert ball bearings with top wire, including wide inner ring UC type and flat head UB type at the end of the inner ring, which are suitable for use of changing rotation direction.

2. Spherical spherical bearings with eccentric sleeves, there are two types: wide inner ring UEL type and flat head UE type at one end of the inner ring, which are suitable for use when the rotation direction remains unchanged.

3. The outer spherical spherical bearing with a tightening sleeve is composed of a wide inner ring UK-type conical hole bearing and a corresponding type of fastening sleeve. It is suitable for changing the rotation direction, high rotation speed, and has a large axial bearing capacity when the operation is stable than that of the top wire and the eccentric sleeve bearing.

The outer spherical bearing and the outer spherical bearing housing can be interchangeable in a variety of structural types.

The main ways to fix the inner ring and shaft of the insert ball bearings with a seat are: locking with fastening screws, locking with eccentric sleeves, locking with fastening sleeves, using over-earning matching method, etc.

The structural types of the insert ball bearings housing mainly include casting seat and stamping seat.

Casting seats include: casting vertical seat, casting high center vertical seat, casting narrow vertical seat, casting convex square seat, casting convex square seat, casting diamond seat, casting adjustable diamond seat, casting convex round seat, casting slider seat, casting ring seat, Casting triangle seat, casting suspension seat and casting suspension seat.

Stamping seats include: stamping vertical seats, stamping circular seats, stamping triangle seats and stamping diamond seats.
