Tapered roller bearings are widely used in roll-neck applications in rolling mills, transmissions, gear reducers, geared shafting, steering mechanisms, and machine-tool spindles. These tapered rollers require lubrication: Where speeds are low, grease lubrication can be used but high speeds demand oil lubrication; very high speeds require special lubricating agents to maintain proper function.
