Part Number MR6903-2RSC This bearing comes with PTFE Heat Resistant Rubber Seals. Ceramic balls are lighter for less centrifugal force allowing motors to spin at a higher RPM and also to accelerate faster. Plaig Bearings are a stronger, more reliable bearing with greater Corrosion Resistance and Durability with superior life to the standard factory bearings. We stock an increasingly large range of bearings, Complete Bearing Kits for many popular RC Cars are also available. If you can’t find the correct bearing by size or part number please contact us. Bearing Materials SAE 52100 Chrome Steel Balls • Higher hardness for longer life ratings • Low cost for high performance • Good for temperatures up to 150°C • Poor corrosion resistance (if left exposed) This is the standard steel for most ball bearings. It is harder than stainless steel and gives greater life ratings. It also has superior low noise qualities to standard 440 grade stainless steel. Chrome steel actually has a low chromium content and is not corrosion resistant, all Plaig bearings are assembled with Shell AF2 Oil as chrome bearings require an oil coating on the exterior surfaces to protect against corrosion which can contaminate the inside of the dry bearing. Chrome steel can tolerate continuous temperatures of up to 150°C. Above this temperature, bearing life is significantly reduced. PTFE Heat Resistant Rubber Seals • Excellent corrosion resistance to water, salt water and most chemicals • Good high temperature performance. • Non magnetic • Only semi-precision grade is possible • Maximum temperature 260°C The PTFE Seal is rubber bonded to a metal washer. The inner lip of the seal rubs against the bearing inner ring to provide an effective seal against smaller particles such as dust and moisture while preventing lubricant leakage. Bearing Retainer / Cage Retainers keep the balls evenly spaced around the raceway preventing ball to ball contact and thus allowing higher speeds. They also help to retain grease around the balls and raceways. For greater accuracy and to prevent any additional friction, it is important that the retainer is not allowed too much radial movement. Our standard bearings use a Carbon Steel Crown Retainer. Why Buy Plaig Bearings Plaig Bearings have been put to the test since 2008, with over 500,000 Bearings being sold across Australia.
