How to choose Conveyor idler material
Clicks:2303 Date:11-21
Conveyor idler is a kind of bearing type which is widely used in bearing industry. Its main components are inner ring, outer ring, rolling body and cage. Among them, deep groove ball ring and rolling material selection is very important. The reason is that these two components are the factors that can affect the performance of Conveyor idler. Technical staff of Yiyang Longma bearing limited company to remind everyone according to different requirements, we should choose different idler requirements with Conveyor rings and rolling body material.
1. High carbon chromium bearing steel
Most of the bearing rings and rollers are made of special steel for use. The bearing rings and rolls made of high carbon chromium bearing steels (GCr15 and GCr15SiMn and ZGCr15 and ZGCr15SiMn) are as follows:
The bearing rings and rolls made of GCr15 and ZGCr15 high carbon chromium bearing steel materials are HRc61~65, and the steel balls are HRc62~66;
The bearing rings and rolls made of GCr15SiMn and ZGCr15SiMn high carbon chromium bearing steel materials are HRc60~64, and the steel balls are HRc60~66.
The bearings made of high carbon chromium bearing steel are normally in grease and grease lubrication, and the applicable working temperature range is generally from 40 degrees Celsius to 130 degrees Celsius, which can meet the requirements of general machinery. High carbon chromium bearing steel bearing parts can be operated normally at a temperature of 250 OC after tempering at high temperature.
2 carburizing bearing steel
The bearing rings and rolling bodies made of carburized bearing steel materials have the following hardness values:
Bearing manufacturing carburizing bearing steel material and the rolling body is HRc60~64, the oil and grease are in the normal work, the applicable temperature range is generally -40 ~140 DEG C, and can be operated in shock and vibration conditions of the larger, such as locomotives, rolling mill bearing etc.. But when using this material to make bearings, the heat treatment process is more complicated.
3, heat resistant bearing steel
The bearing ring and rolling body made of heat-resistant bearing steel material have the following hardness:
The bearing rings and rolls made of heat resistant bearing steel are HRc60~64 and steel balls are HRc61~65. When the grease and grease lubrication are all normal, the applicable working temperature range is generally 120 ~250 C, such as gas turbine, aero engine and other spindle working conditions.
4. Corrosion resistant bearing steel
The bearing rings and rolling bodies made of corrosion-resistant bearing steel materials have the following hardness values:
The smallest ring and roller are HRc58, which can be used in water containing, nitric acid, chemical reagents and other corrosive media. The applicable temperature range is -253 degrees ~350 degrees centigrade.
