NSK bearing rolling appearance if cracking, creasing or rust, will attack like rivet rivets periodic vibration and noise, the cycle can be fixed but most must correspond with the speed, scars are continuing attacks on the channel, scars on the ball disappeared, and this premise installation and smooth the noise but without a necessary change.
Such moderation approach to noise: device not tapping bearings, NSK bearings and shaft assembly after mount housings to avoid NSK bearing slant; inventory to avoid corrosion of bearings and transport to avoid vibration and shock to use smooth fat for high viscosity.
Rolling bearings with dust and other foreign bodies, will attack non-periodic oscillation and the so-called dust, vibration and noise of the large and variable, and with or without.
Moderation approach to dust: cleaning approaches to improve the bearing, bearings, shafts, holes before installation, as well as match part all stringent clean Shen Qing; out foreign bodies smooth agent, improving NSK bearing seal; preventing impure or embedded with foreign objects using information the plastic stick.
Selection errors, lack of lubricant or lubricant ageing attack induration, and have incurred NSK bearing vibration and noise, this noise and no rules. This situation, as long as the selection of appropriate smoothing agents, adjusting its smooth-dose extended smoothing agent for change determination and application life cycle.
First, and check NSK bearing in work in the of vibration situation from peeling, and pressure trace, and rust, and crack, and wear, will in bearing of vibration measurement in the reflect, bearing vibration on NSK bearing of injury is is sensitive of, therefore, and through used special of bearing vibration measurement Manager (frequency Analyzer,) can measurement out vibration of size, through frequency points not inferred out exception of specific situation. Due to the conditions of use of measured values for bearings or sensor installation location different is required prior to analysis and comparison of measurement values of each machine are determined their criteria.
Second, check NSK bearings rolling sound because the bearings even with minor injuries such as split, also is making an abnormal sound and irregular sound, so logging can be distinguished using acoustic logging, NSK bearings in operation size of the scrolling and sound checks, play the role of prevention in advance.
Third, NSK bearings rotate the temperature if you want to check oil hole can directly measure the bearing outer ring temperature, is more appropriate. Under normal circumstances, the bearing temperature, NSK bearings based on outside of room temperature can speculate. If lubricated, install suitable, the bearing temperature dramatically increased, abnormal high temperature occurs, in which case you must stop and take the necessary precautions.
