DESCRIPTION
NEWMEN ball bearing BB CB 17x30x7 CN LULH for hub body
Original replacement deep groove ball bearing from Newmen if your bearing is worn or damaged.
Heavy Duty version - these bearings are slightly heavier but their larger design makes them much more resilient and resistant. Important: when fitting the bearings, the bearing reducers must be removed or not fitted at all.
Newmen only uses high-quality deep groove ball bearings with bearing clearance C3. Ball bearings with cages and smooth-running seals are used on all lightly rotating components, such as the hub bodies. Full complement bearings are used for components that rotate slowly and are subject to high loads, such as the freewheel body. Full complement bearings have a higher load rating and can withstand higher loads than normal ball bearings with a cage.
A ball bearing always requires a certain amount of bearing play to ensure that it functions permanently and that the lubricating film is not interrupted.
