A cotton yarn machine producer asked NSK for a bearing handling training in terms of proper lubrication. The customer experienced difficulties in lubricating the bearings due to the small gap between the rings and cage. This resulted in grease wastage and unsatisfactory lubrication of the bearing. They consulted NSK who designed and produced a special nozzle and grease pump. The customer was then trained in best practice lubrication techniques using the new grease pump and nozzle this resulted in reduced grease losses and no further problems with relubrication.
