WHEEL BEARING INFORMATION
Sealed Bearing 2RS - DDU
All the wheel bearing we supply are 2RS - DDU.
Double sealed and ready lubricated with premium grease for added protection against dirt and water ingress and are made of high strength AISI 52100 chrome steel components for the rolling elements and the inner and outer rings; to ABEC 1 dimensional tolerances and C3 radial clearance tolerance.
The bearings also undergo electronic noise and vibration testing according to ANSI/AFBMA Standard 13-1987.
Care And Maintenance
Although bearings are subjected to large amounts of stress and are continually being used to fulfil various duties, they are precision made and typically last a long time (bearing failure is often due to improper installation and fitting). However high-mileage bikes and dirt bikes, which are exposed to a lot of mud and water, can become vulnerable and require attention sooner than expected.
Creaking, strange noises or lumpy turning of the wheel as it rotates are early signs of bearings which require attention.
It is important to identify these early signs as they can quickly worsen to the point of further damaging other parts of your bike.
