What is SUJ2 steel?
JIS SUJ2 Steel is a high quality Alloy Bearing Steel, It belong to the high quality high carbon alloy Bearing Steel. Quenched & Tempered Hardness is 28-34 HRc. SUJ2 steel Annealing delivery hardenss less than 250HB.
What is steel bearing?
Bearing steel is special steel featuring high wear resistance and rolling fatigue strength. The material, featuring high wear resistance, corrosion resistance and heat resistance, is used to make bearings mounted in an oxidizing atmosphere or high temperature, where corrosion of material is accelerated.
What is SAE 52100 steel?
SAE 52100 is an alloy steel with high carbon with chromium as an alloying element, which has been widely applied in rolling bearings . The traditional heat treatment process for SAE 52100 steel consists of a quenching process followed by a tempering step at low temperature.
What is EN24 material?
EN24 is a very high strength steel alloy which is supplied hardened and tempered. The grade is a nickel chromium molybdenum combination – this offers high tensile steel strength, with good ductility and wear resistance characteristics.
What is bearing hardness?
The most common material used to produce the load carrying components in precision ball bearings, roller bearings, and tapered roller bearings is 52100 chrome steel. The typical surface hardness for bearing components made from this material ranges from 60- 64 on the Rockwell hardness C scale (Rc).
How do you choose bearing material?
Consider polyamide cage and/or ceramic balls for higher speeds. High temperature use (up to 250°C constant), very low load/speed. Use corrosion resistant 440 stainless steel bearings with high temp grease or unlubricated plastic PTFE/PEEK bearings. Beware lower rolling accuracy of plastic bearings.
What is the difference between EN8 & EN24?
EN8: It is a steel grade which has 0.4% carbon and 0.8% of manganese. Application: Mainly used for shaft and structural applications. EN24:It is a steel which has Ni-Cr-Mo as an alloying elements. EN 24 is generally used in the volume hardened condition.
What is the hardness of P20 steel?
P20 tool steels are tempered at 482-593°C (900 to 1100°F) for a Rockwell C hardness of 37 to 28.
Can a 52100 be case hardened?
52100 steel is a high carbon chromium alloy steel that has a density of 7.81 g/cm3 (0.282 lb/in3). It can be hardened via cold and hot working processes and responds to annealing and tempering and can be strengthened using the heat treatment process.
