Electric Vehicle Specific Bearing 6203 -2RS

Electric Vehicle Specific Bearing 6203 2RS ​​Standard Grade C3 HG03 Grease (-40~180℃)

Electric vehicles (transmissions and axles) generally use 8 sets of bearings. The main requirements for these bearings are as follows:

① Rotational speed generally needs to reach over 8000 RPM

② The bearing should not leak oil during high-speed operation

③ Good dustproof performance, capable of preventing external dust from entering the bearing

④ Able to withstand strong impact loads

BLH bearings, designed and manufactured to meet the above requirements, have been widely used in electric vehicles of internationally and domestically renowned brands.

Electric vehicle specific bearing 6203 2RS are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies.These products, which are of simple design, robust in operation and easy to maintain, are available in single and double row designs and in open and sealed variants. Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields. Due to their low frictional torque, deep groove ball bearings are suitable for high speeds.

Due to the raceway geometry and the balls used as rolling elements, Electric vehicle specific bearing 6203 2RS can support axial loads in both directions as well as radial loads

Electric vehicle specific bearing 6203 2RS are suitable for high to very high speeds.Deep groove ball bearings with the suffix 2Z have gap seals on both sides and are suitable for high speeds.Bearings with the suffix 2RS have lip seals on both sides are suitable for moderate speeds.By agreement, we can supply bearings with non-contact BRS seals on both sides (suffix 2BRS). These bearings have favourable frictional behaviour equivalent to that of bearings with Z seals . If the inner ring is stationary and the outer ring rotates, the lubricant loss is less than that in bearings with Z seals .

Electric vehicle specific bearing 6203 2RS can be lubricated with grease or oil.Deep groove ball bearings with gap or lip seals on both sides are greased with a high quality grease and are lubricated for life.

DElectric vehicle specific bearing 6203 2RS can be used up to an operating temperature of +180 °C. For applications at temperatures above +180 °C, please contact us. Bearings with a diameter D of more than 240 mm are dimensionally stable up to +200 °C.Deep groove ball bearings with lip seals can be used at operating temperatures from –40 °C to +180 °C.Bearings with cages made from glass fibre reinforced polyamide are suitable for operating temperatures up to +180 °C.
