To discriminant removed nsk tapered roller bearings ability to be able to use wash clean after checking in the bearing. Check the raceway, the raceway, with the state of the surface, adhere to the wear of the rack, the increase of the bearing clearance and independent of the size precision landing damage, abnormal. Non-parting small ball bearings, with one hand, the inner degree of support, rotating outer ring to confirm whether the fluent.

Overhaul of bearings: bearing cleaning: remove nsk tapered roller bearing maintenance, first recorded the appearance of the bearings to confirm the residual amount of smooth agent, sampling check with smooth agent, wash bearings. As cleaning agents, gasoline, kerosene.

Are bearing industry, the use of the type of grease high speed wire rod mill bearing, accounting for sub-70% of the fat content. Since the type of grease selection of the fiber soft, light difficult to filter lithium to waste a thickening agent, the use of mineral oil as basic oil is very light is difficult to know the feet outside the low-end bearings reduce vibration values. Another interest is inferior benign pumping, whether it is mechanical fat is still hand-painted resin, both simple and difficult. The grease, and low price, can greatly reduce the cost of nsk tapered roller bearings. However, due to the use of the fundamental mineral oil, so that the grease is rust and anti-rust function outside of the physical and chemical target to play the co-buckle. Such as the bearing life can only be up to 200 hours, the linear guide Frequently Asked Questions. Starting and running torque is -20 ℃ test, no problem. Class grease the use of temperature is generally -20 to 120 ℃, high temperature use is 150 ° C or more, arise from excessive evaporation of the fundamental oil, drain off the stern and other phenomenon, greatly reducing the bearing using life.

1. smooth bearings, oil bath

Smooth oil bath bearing ordinary smooth, suitable for low-, medium-speed bearing smooth. Will be the nsk Tapered Roller Bearings local dip in from the slot, smooth oil is brought up by the rotation of the bearing parts, and then flow back into the center of the tank oil level should be slightly less than the minimum of the rolling elements.
Smooth bearing drip

2.Drip smooth suitable for the need to smooth and quantitative supply of oil was nsk tapered roller bearing components, individual drip volume one drop every 3-8 seconds is appropriate, too much oil will cause increased bearing temperature.

3 smooth bearing circulating oil
Applying by nsk tapered roller bearings after smooth oil filter cooling pump to filter the oil recommended for admission to the bearing components. Cycle oil can be taken away by the positive heat, so that the bearing cooling, therefore the approach is useful in high speed bearing components.

4. bearing the spray smooth

Air through a nebulizer boring contraction caused oil mist mixed with the smooth oil, radial bearings, the air flow can effectively make the bearing cool down and avoid intrusion of impurities. This method is suitable for high-speed, smooth low-temperature bearing components.
Bearing the radiation is smooth

Low-pressure oil through the nozzle pump will reach all parts of the the nsk tapered roller bearings, launched into bearing in the oil bearing the other end into the tank. Bearing the high-speed rotation, the rolling body and maintain frame commensurate with the high rotation speed of the ambient air caused by air flow, individual smooth way it is difficult to smooth oil to the bearings, when necessary for low-voltage radiation will smooth the way oil spray to the bearings, the status of the nozzle should be placed on the inner ring and between the maintenance of aircraft central.
