Often use gasoline, kerosene as an ordinary detergent. NSK Bearings dismantled overhaul, the first recorded appearance of the bearing, confirm, start a wash stainless steel bearings residual lubricants, lubricating oil sampling amount. Coarse and fine cleaning, cleaning cleaning point, respectively, in the container, first put the net metallic bottom, so there is no direct contact with the container bearing the dirt.
A coarse cleaning, use a brush to remove grease, adhesive material, generally clean, wash into a fine. If the dirt and the bearing rotation, will damage the bearing rolling surfaces, should be addressed.
2, spermatogenic clean oil bearing side rotation, and carefully cleaned. In addition, cleaning the oil must be kept clean.
NSK Bearings Maintenance and judgment: To determine the bearing is removed, can be used for cleaning up the rear bearing.
Maintenance includes: monitoring working conditions, supplement and replace the lubricant regularly demolition inspection, it is best to maintain appropriate operating standard machine regularly working conditions. Maintenance operations, a spinning sound, vibration, temperature, lubrication conditions, bearings and other separation-shaped bearing problems, you can scroll through the body, the outer ring raceway surface were examined.
Check the raceway, raceway, cage wear surface condition, stainless steel bearings gap increases, and there is no damage to the unusual size of the decline in accuracy. Non-separable ball bearings, on the one hand the inner level of support, rotating outer ring confirmation smoothly.
Large bearings, because they can not rotate by hand, be careful to check the rolling element raceway, cage, ribs and other surface appearance, bearing higher importance, but should carefully checked.
1, through the surface bearing quality feeling
I'm in the process of selling NSK Bearings found that many customers say as long as the bearing surface brightness is of good quality, which is wrong. Bearing surfaces should be kind of bright glossy black, glossy black reasons causing this bearing steels are used in compliance with its grinding and cutting fluid used, such as arising, in which the former two based.
2, chamfer is bright
Bearing chamfer does not determine the quality of stainless steel bearings, but reflects the processing method of the bearing. Chamfer is black, shows that, after hardening heat treatment, thus increasing the hardness of the bearing, and some people think that the chamfer is black does not look good is not processed completely, this is a misunderstanding.
3, one of the cage than two body good, although the use of new technology are integrated cage, but it is only saves material, while rotating, worse performance than the two bodies.
Overall, NSK bearing life has a relationship with the three factors, namely the quality of the bearing itself. Second, the use of the environment. Third, the installation method.
