The current domestic application of 608 bearings is already very extensive, but the application industry is different, and the requirements are more and more. The production plant has to research and develop various materials again and again, and the properties of various materials are different to meet different needs. The demand of the industry, Jiashi Bearing has accumulated for many years, and has produced the following materials:
Bearing steel material
Bearing steel domestic 608 bearings are suitable for high speed or even high speed operation, and are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient, a high limit speed, and a variety of sizes and forms. It is used in air-conditioning motors, household fans, precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is a machinery industry and a common electrical appliance. The most widely used type of bearing. It mainly bears radial load and can also bear a certain amount of axial load.
Stainless steel material
1. SUS420
420 stainless steel is a martensitic stainless steel. The domestic 608 bearing produced with this material has certain wear resistance and corrosion resistance, and high hardness. It is suitable for all types of precision machinery, bearings, electrical, equipment, instruments, Instruments, transportation vehicles, household appliances, etc. Mostly used to manufacture parts resistant to atmospheric, water vapor, water and oxidizing acid corrosion
2. SUS440 (9Cr18Mo)
Martensitic stainless steel has a higher carbon content than cr13 steel, so its strength and hardness are higher than cr13 steel. Other properties are similar to cr13 steel. But the weldability is poor, and it is usually not used as a welding material. The domestic 608 bearing of this material is used to manufacture surgical tools. The steel also has good high temperature dimensional stability, corrosion resistance and toughness are very strong, and is now more widely used in hand-made knives and high-quality factory-made knives.
3. SUS304 (06Cr19Ni10 / 0Cr18Ni9)
304 austenitic stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, non-magnetic 304 stainless steel is widely used for its good heat resistance It is used to make equipment and machine parts with corrosion resistance and formability. At present, 304 stainless steel has been widely used in food, chemical, atomic energy and other industrial equipment and decoration fields, as well as household goods, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemicals, food industry, agriculture, Ship parts.
4. SUS316 (0Cr17Ni12Mo2)
316 austenitic stainless steel has plasticity, toughness, cold deformation, good welding process performance, and good appearance gloss of cold-rolled products; due to the addition of Mo (2 ~ 3%), corrosion resistance, especially excellent pitting corrosion resistance, high temperature strength Excellent, excellent work hardening (weak magnetic after processing), non-magnetic in solution state, good welding performance. This material is relatively rare in the domestic 608 bearing industry, and can be welded using all standard welding methods.
