XRay High Speed Ball Bearing 12X18X4 Rubber Sealed (2)

The XRAY High Speed Ball Bearing 12x18x4 Rubber Sealed (2) – part number XR941218 – is engineered for a free-running, ultra-smooth drivetrain. Manufactured specially for XRAY, each 12x18x4mm bearing is degreased and lightly oiled with AeroShell Fluid 12, then fitted with rubber seals to deliver smoothness, long life and high precision.

Compared with standard bearings, these feature more – and larger – balls inside the cage for improved resilience under heavy loads. Removable side covers allow quick, comfortable servicing, while the ultra-high precision construction is designed to cope with the extremes of on-road racing as well as regular fun running.
