Size 22X58X21mm Motorcycles Deep Groove Ball Bearings Vkt1000 Bb1-3155 X2 Manual Transmission Bearing Assembly. Original SKF BB1-3155 gearbox bearings carry high European import cost and long overseas delivery lead time. Standard equal-width ordinary bearings have short inner ring matching length, easy loose clearance and shaft shaking after short mileage driving. Single-layer weak seal bearings leak internal lubricating grease quickly, produce continuous squeaking noise and fail within 30,000 KM.
