As a blend of cylindrical roller bearings INA bearing, in peacetime operation, how to moderate mixed INA bearing lubrication mixed INA bearing maintenance and repair work is also an important element that should not be ignored.
　　Smooth oil bath is the most mixed INA bearing ordinary smooth way, suitable for low and medium speed mixer INA bearings for smooth. Cylindrical roller bearings with a partially immersed in the slot, smooth by rotating mixers INA bearing parts, then flow back into the oil tank oil level should be slightly lower than the center of the lowest rolling element.
　　Drop of oil was smooth smooth oil suitable for quantitative supply mixed INA bearing part, drop a drop of oil content of individual 3-8 second, too much will raise the amount of oil mixed INA bearing temperature increases.
　　Oil pump filter oil sent to mixed INA bearing part, after adoption of cylindrical roller bearings and smooth after oil filter cooling application. Because of circulation oil can be taken away for sure heat, to cool off the mixer INA bearings, therefore law applied to high speed of mixer INA bearing parts.
　　Dry shrinkage caused by air through sprayer mixed with varnish oil mist, radiation in cylindrical roller bearings, air can effectively cool mixer INA bearings and can avoid the intrusion. This method is suitable for high-speed, low-temperature mixed INA bearing parts of smooth.
　　Low pressure oil nozzle with a pump laser in cylindrical roller bearings, into oil mixer in mixers INA bearings INA bearings flows into the tank at the other end. INA bearings rotate at high speed in mixer, rolling and maintained also with commensurate high rotating speed so that the surrounding air causing air flow, individual smooth manner difficult to varnish to the mixer in INA bearings when necessary using a low-voltage radiation of smooth oil spray to cylindrical roller bearings, nozzle position should be placed between the inner ring and maintain Central.
　　1) compared to ball bearings and roller bearings, have a higher speed limit, it should be preferred in high speed ball mixer INA bearings.
　　2) in diameter under the same conditions, smaller diameter, are more rolling light small, running on the rolling elements and the outer ring raceway of centrifugal inertial force is smaller, thus more suitable to work in higher speed. When placed in high speed, use a super light, super light and light series mixer INA bearings. Heavy and super heavy series of cylindrical roller bearings, only used for situations where low-speed and heavy. If a light series mixer does not meet the requirements of INA bearings and bearing capacity, wide series of mixer INA bearings could be considered, or mounted on two light series bearings and use.
　　3) material and structure of the cage effect on mixed INA bearing speed greatly. Solid cages than some cages allow for higher speeds.
　　4) permission to mix INA bearing speed, are very low. When working at the high speeds if axial loads is not very large, you can use angular contact ball wheel bearing subjected to purely axial force.
　　5) if the speed slightly in excess of speed limit stipulated in the samples of work, improving INA bearing tolerance class can be used, or appropriate to boost hybrid INA bearing radial clearance, selection of circulation lubricated or oil mist lubrication, enhance circulation oil cooling measures to improve high speed performance of cylindrical roller bearings. More if the work speed exceeds the speed limit, magistrates or city mixed with special high speed scrolling INA bearing.
　　In normal speed, high and low speed type select what effect does not occur, only when high speed, there will only be more marked effect. Was included in the mix to INA bearing samples of various types and sizes mixed INA bearing limit speed nlim value. This speed means the load is not too big (p ≤ 0.1C,C for the basic dynamic load rating), the normal cooling conditions, and 0 k of tolerances for cylindrical roller bearings when the maximum allowed speed. However, because the speed limit is mainly limited by the temperature rise when working, therefore, could not be considered speed limit is one of the sample must not go beyond the bounds of. If the mixer of INA bearings work when the speed exceeds the speed limit, you can take the following measures 5th section.
