INA bearing as one of the import bearings, in the process of running at ordinary times, how to moderate to bearings of lubrication also bearing the care and maintenance is not allow to ignore one of the most important parts.

Oil bath smooth is the most common way of bearing smooth, suitable for low, medium speed bearing smooth. Will a local dip in bearing by tanks, smooth by the oil rotating spherical roller bearing parts take on, and then come back to the oil tank face should be slightly lower than the minimum in the middle of the roller.

Drops of oil is suitable for quantitative supply to smooth smooth oil bearing parts, dripping oil every 3 to 8 seconds individual a advisable, too much oil amount will cause bearing temperature increased.
Be filtered with oil pump oil walks to the INA bearing parts, through the bearing the smooth again after oil filter cooling after use. Circulation oil can take away because certain quantity of heat, make bearing cooling, reason this law in high speed of practical self-aligning roller bearings components.

With a boring contraction air after spray oil mixed with smooth caused by oil mist, radiation bearing, the air can effectively make bearing cooling and can avoid impurities invasion. This method is suitable for high speed, low temperature bearing parts of smooth.

With low pressure oil pump will through the nozzle to shoot to bearing, into the oil in the bearing of the bearing the other end into the oil. In bearing high speed rotating, rolling body and maintain a high proportion of in rotation speed air around that caused by air, with individual smooth ways hardly will smooth oil to bearing, then must use the low voltage radiation way will smooth oil spray to bearing, nozzle should be put in the position of the inner circle and maintain a central between.

1) ball bearings and roller bearings compare, a higher limit rotational speed, therefore, in high speed should first choose ball bearings.

2) in diameter of the same conditions, the smaller the outer diameter, the roller is light and small when working with roller in the outer ring road roll of the smaller the centrifugal force, so there was more suitable for higher speed in work. In high speed, appropriate chooses, super light, and light the light series bearing. Weight and higher series of spherical roller bearing, only for the occasion of low speed and heavy. If use a light series INA bearing and bearing capacity of short of asks, can consider to use wide series of bearing, or put the two light series of bearing and packaged in are used together.

3) keep frame of material and structure has great influence on the bearing speed. Entity maintains a stamping maintains a allow higher than some of the speed.

4) bearing permissions speed are very low. When work high speed, if not axial load is very big, can be used for Angle contact ball bearing the wheel under pure axial force.

5) if working speed slightly more than samples specified in the speed limit, can use improve spherical roller bearing tolerance level, or increasing the appropriate of the bearing radial clearance, choose circulation lubrication oil mist or lubrication, strengthen to the circulation of oil cooling measures to improve the bearing of the high-speed performance. If working speed limit speed more than more, should choose special high-speed roller bearing.

In general rotating speed, the discretion of the speed of type of choose not to happen that affects only in high speed, just to have a more significant impact. INA bearing samples on the all types and sizes of bearing limit speed nlim value. The speed is not too big to load (P than 0.1 C, C rated as the basic dynamic load), cooling condition normal, and for 0 level of maximum allowed tolerance bearing speed. However, because the main limit speed by work of temperature rise is limited, therefore, can not think in the sample limit rotational speed is a absolutely not beyond boundaries. If spherical roller bearing rotating speed limit speed of more than, can adopt the following article 5 of the measures put forward.
