Introduction to bearings
HRBPT stainless steel bearings have good oxidation resistance; Corrosion resistance and non-magnetic properties, especially suitable for harsh production environments, with a high ability to withstand; High lifespan; Maintenance free. Harbin Bearing Group Tieli Bearing Co., Ltd. is able to organize mass production of stainless steel bearings, achieving high strength and high precision. Stainless steel rolling bearings can be used under special conditions such as acid and water resistance, and due to their high mechanical strength and load capacity. Widely used in food processing, medical machinery, and pharmaceutical machinery, with a wide range of applications.
High performance stainless steel bearings provide high precision and wear resistance comparable to high carbon chromium steel on the basis of cleanliness and corrosion resistance, with precision reaching ISO standard ABEC-1 or above. Vibration level Z1 group or above.
The bearing rings and rolling elements are made of AISI SUS440C stainless steel (domestic codes: 9Cr18Mo, 9Cr18) that has undergone vacuum quenching and tempering treatment. The cage and sealing ring skeleton material are made of AISI304 stainless steel (domestic code: 1Cr18). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. By selecting appropriate lubricants, dust covers, etc., they can be used in environments ranging from -60 ℃ to+300 ℃. Stainless steel deep groove ball bearings are equipped with dust covers. Some are also equipped with contact seals. Bearings equipped with dust covers or seals on both sides adopt a lifelong lubrication method and do not require maintenance. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and high load capacity.
BEARING CHARACTERISTICS
Size range:HRBPT bearings offer full-size stainless steel bearings, including miniature stainless steel bearings with an inner diameter of 2 millimeters and large stainless steel bearings with an inner diameter exceeding 200 millimeters. We have inventory of over 2000 stainless steel bearing models and can also customize stainless steel bearings according to customer requirements.
Sealing form:Stainless steel sealed bearings can choose from various sealing forms, including rubber cover sealing, metal sealing, and Teflon sealing. Has good waterproof effect.
High temperature&high speed:As a leading domestic manufacturer of stainless steel bearings, HRBPT bearings provide high-temperature resistant high-speed stainless steel motor bearings that meet the requirements for use in harsh environments.
Advantages of bearings
Excellent corrosion resistanceHRBPT stainless steel bearings are not easy to rust and have strong corrosion resistance.
Machine washableStainless steel bearings can be washed without the need for re lubrication to prevent rust.
Can run on liquidsDue to the materials used, we can operate bearings and bearing seats in liquids.
Slow depletion rateAISI 420 stainless steel, does not require oil or grease for corrosion protection. Therefore, if the speed and load are low, lubrication is not required.
hygieneStainless steel is naturally clean and non corrosive.
High heat resistanceStainless steel bearings are equipped with high-temperature polymer cages or cages without a complete repair structure, and can operate in a higher temperature range of 180 ° F to 1000 ° F. (High temperature resistant grease is required)
