Introduction to commonly used rolling elements in slewing bearings

Publish time:2021/07/08 News Views:71

There are two types of rolling elements used in common slewing bearings, steel balls and rollers.

 

Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production and processing technology. According to the processing materials, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, ceramic balls, glass balls, alloy balls, etc. Among them, most of the slewing bearings are bearing steel balls. Bearing steel balls have a long history of use in the precision bearing industry and life and they are more widely used. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls or balls.The production of steel balls is divided into stamping-make to circle-quenching- grinding after quenching-preliminary grinding-inspection-finish grinding–ultra precision grinding-cleaning-rust-proof-finished product-packaging and other processes. Steel ball appearance inspection is an indispensable process in the process of steel ball processing.

There are many types of rollers, which are classified into tapered rollers, cylindrical rollers, spherical rollers, spiral rollers and various needle rollers according to their shape and size. Cylindrical rollers are the most commonly used in slewing bearings. The production of cylindrical rollers is divided into rough turning-quenching-rough grinding-inspection-finish grinding-ultra precision grinding-cleaning-rust-proof-packaging and other processes.

 

Rollers and steel balls belong to the same rolling elements. They are the most important part of slewing bearings and the most used rolling elements in the bearing industry. The quality of the rollers and steel balls directly affects the quality and service life of the bearing, so it’s necessary to choose rollers and steel balls produced by reliable quality manufacturers.
