Four-row tapered roller bearings
The design principle of the four-row tapered roller bearing is to improve the carrying capacity of the rolling mill bearing as much as possible by optimizing the structure in a limited assembly space.
Four-row tapered roller bearings are generally mounted on the roll neck with clearance fit for easy installation and disassembly. Due to the possible slippage between the inner ring hole and the roll neck, proper lubrication should be maintained on the contact surface to avoid wear. In order to prevent the inner ring end face and the inner spacer end face from sliding and rubbing each other, lubricating oil grooves are formed on both end faces of the inner ring and the inner spacer. There is an oil groove and several oil holes on the middle and outer rings.
