Product Description | |
8x16x5mm Bearings, 10 Tubes of 10 Bearings (100 Bearings in total), with Blue PTFE Heat Resistant Rubber Seal. This bearing is used in a large range of RC cars. Plaig Bearings are a stronger, more reliable bearing with greater heat resistance and superior life to the standard factory bearings. We stock all other sizes of bearings for RC Cars and also sell Complete Bearing Kits for many popular brands of vehicles. If you can't find the right size 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.
• 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.
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. |
