Depending on the application, brass plates and stainless steel plates are also used.This article is provided by Changzhou Youcheng Bearing Factory.cage material:  stamping cage material, using low carbon steel.com The ferrules and rolling bodies of needle roller bearings are repeatedly subjected to high contact pressure on one side, and on the other side they are in rolling contact by sliding down.　　

Bearings are vacuum degassed, so the materials used have high cleanliness, low oxygen content and good quality. Therefore, the material, performance, and main requirements for bearing rings, rolling bodies and cages are as follows. Furthermore, proper heat treatment is adopted to significantly increase the life of the bearing's rolling fatigue.　　

The material of the ring and rolling body: The ring and rolling body are usually made of high carbon chromium bearing steel. Carburized bearings with proper hardening depth, fine structure, proper hardness of surface and core hardness, have better impact resistance than bearings using bearing steel, and the chemical composition of general carburized bearing steel.　　

Features required for ferrule and tumbling body materials:  high abrasion resistance Cage material requirements: good dimensional stability and high mechanical strength. For more information, please continue to pay attention to Bearing, we will serve you wholeheartedly!. In addition, good workability is required. The material for cutting the cage is made of high-strength brass, carbon steel, and synthetic resin. The retainer is in sliding contact with both sides of the ferrule and the Wheel Bearing suppliers tumbling body, or one side thereof, and bears the tensile force and the compressive force.　　　　

When further impact resistance is required, chromium steel, chromium-molybdenum steel, nickel-chromium-molybdenum steel are used as bearing materials, and carburizing and quenching are used to make the steel have a hardened layer from the surface to an appropriate depth. SUJ3 is used for large bearings. For more information about needle roller bearings.　

In addition to the above-mentioned steel grades, high-speed steel with excellent heat resistance and stainless steel with good corrosion resistance are also used for special applications. Most of the bearings use SUJ2 in JIS steel grade. Depending on the application, there is also demand for good impact resistance, heat resistance, and corrosion resistance.
