Tapered roller bearings and other separation-shaped bearing, you can scroll through the body, the outer ring raceway surface were examined.
Large NSK Bearings rotated by hand because they can not pay attention to check the rolling body raceway, cage, ribs and other exterior surfaces, NSK Bearings higher the greater the need for the importance of careful examination.
NSK bearing lubrication purposes:
Rolling bearing lubrication to reduce internal friction and wear, to prevent burning stick, its lubricating effect is as follows.
(A) to reduce friction and wear.
Constituting the NSK bearing rings, rolling elements, and each contact portion of the retainer to prevent the metal contacts, reducing friction and wear.
(2) extend the fatigue life.
NSK Bearings rolling fatigue life, in the rotation, the rolling contact surfaces oiled, then extended. Conversely, low viscosity oil, the lubricant film thickness is not good, is shortened.
(3) discharging the friction heat and cooling.
Circulation to the oil law and other oil discharge occurred by friction heat, or heat coming from the external cooling. NSK Bearings prevent overheating and to prevent lubricant itself aging.
(4) Other
Also prevent dust and debris inside the bearing NSK, or to prevent rust, corrosion effect. Lubrication method:
NSK bearing lubrication methods, divided into grease and oil lubrication. In order to make a good play function NSK Bearings, first, to select the appropriate conditions of use, purpose of use lubrication method. Only consider lubrication, oil lubrication dominant. However, there can be simplified NSK grease around the bearing structure of expertise, the grease and oil lubrication compare the pros and cons.
NSK Bearing Installation:
NSK bearings are correctly installed, affecting accuracy, longevity, performance. Therefore, the design and installation of the bearing assembly department to be adequately studied. I hope to be in accordance with the operating standards for installation. The projects are usually operating standards are as follows:
(1) Cleaning NSK bearings and related components;
(2) Check the connected components of size and finishing conditions;
(3) Installation;
(4) NSK Bearings installed after the inspection;
(5) supply of lubricant.
