FAQ:

Q: What is a machine bearing?
A: Bearings are "parts that assist objects' rotation". They support the shaft that rotates inside the machinery. Machines that use bearings include automobiles, airplanes, electric generators and so on

Q:Is bearing steel standard?
A:According to the heat treatment and application, the standard divides bearing steels into five categories: fully quenched bearing steels, surface quenched bearing steels, induction quenched bearing steels, stainless bearing steels and high-temperature bearing steels.

Q: What are the main bearing materials?
A: A typical tri-metal performance bearing consists of a steel backing, a substrate usually made of bronze (copper/lead), and the overlay, which can be made of several metals. The two basic types of overlays used in performance engine bearings are copper, tin, lead, or lead indium.

Q:What is bearing specification?
A: A bearing number is composed of a basic number and a supplementary code, denoting bearing specifications including bearing type, boundary dimensions, running accuracy, and internal clearance.

About Bearing:

Apered roller bearings are separable and have thefollowing components: outer ring, inner ring, androller assembly (containing the rollers and a cage).The non-separable inner ring and roller assembly iscalled the cone, and the outer ring is called the cup.nternal clearance is established during mounting bythe axial position of the cone relative to the cup.
Taper roller bearings belong to detachable bearingsand are divided into single, double and four-rowtaper roller bearings according to the number ofrolling body columns. Widely used in automobiles.rolling Mills, mines, metallurgy, plastic machineryand other industries
