Swivel ball joint rod end material and bearing capacity

- Apr 02, 2018 -

Swivel ball joint rod end is a special bearing structure, it can be divided into two categories, one is a straight rod type rotary ball joint bearing, its ball seat is made of a special zinc-based alloy, and the ball head rod The material is carbon steel and its operating temperature range is -25°C to +120°C.

 

The other type is bent-bend-type swivel ball joint rod end bearings. There are several series of products here. Some ball-bearing type spherical ball bearings have been cast from a special zinc-base alloy. The material of the ball-head rod is carbon. steel. Some end materials are carbon steel, galvanized on the surface, and extruded; the inner ring material is the bearing steel, quenched, and the ball is plated with hard chrome; the ball head rod is made of carbon steel, and the operating temperature range is -50°C~+150. °C.

 

Regardless of the type of swivel ball joint rod end, it mainly bears radial and axial combined load during its use, and its bearing capacity depends on the raceway angle of the outer ring. The greater the ability.

 

Most of the axial load capacity of a rotary ball joint bearing is determined by the contact angle. The larger the angle, the higher the axial load capacity. The size of the angle is expressed by a calculation coefficient. The larger the value of e, the greater the contact angle and the greater the suitability of the bearing to withstand the axial load.

 

Swivel ball joint rod end bearings are usually of separate type and are widely used in automobiles, rolling mills, mines, metallurgy, plastics machinery and other industries. When installing, it is necessary to pay attention to avoid deformation of the ball, or the defects of the ball seat, which will directly affect the entire The normal use of the bearing.
