Bearing in using process in the due to itself quality and external conditions of causes, its hosted capacity, and rotating precision and wear performance, will occurred changes. Dang bearing of performance indicators below using requirements and cannot normal work Shi, outside spherical bearing on occurred has fault even failure, NSK bearings once occurred failure, accident situation Hou, machine, and equipment will will stopped go, appeared features lost, various exception phenomenon, therefore needs in short-term within identified occurred of causes, and take corresponding of measures.
High temperature viscous combination oil thickener and adds multifunctional additive, is a long term high temperature environments to maintain normal operation of high quality grease.
A very high capacity and high speed shear capacity, make it under the environment of high temperature and high speed to cope.
B an excellent high and low temperature resistance, lubricity, colloidal stability and good mechanical stability.
C service temperature range is-40~230℃, up to 250 ° c for a short time.
D applies to reduce noise or use extreme mechanical use of the environment, also applies to parts of the high-temperature lubrication.
E waterproof, strong, can withstand water, and keep the hardness in a broad temperature range. Excellent resistance to oxidation, anti-wear properties, resulting in extremely long service life, life is 5-10 times the lithium grease.
F suitable for high precision bearings at low temperature, motor bearings, miniature bearings lubricated.
G applies high-speed gyro motor bearing, high-speed, long life, high speed grinding machine and other high-speed instruments and machinery lubrication of spherical roller bearings.
H smooth organization structure, fibers and delicate, with high cleanliness, can inhibit the abnormal sound of bearings in the operation of the, meet the DN value in long-term operational requirements more than 500,000 high speed bearings.
Outside spherical bearing of vibration on bearing of failure effect is obviously. such as: peeling, and pressure marks, and rust, and crack, and wear, will in NSK bearing vibration detection in the reflect out, so through used special of bearing vibration measurement device (frequency Analyzer and vibration instrument,) can measurement out vibration of size, through frequency distribution can inferred out exception vibration of specific situation, measuring have of numerical due to bearing of using conditions or sensor installed location, and different, Therefore require prior to each machine analysis and comparison of measurement values to be determined criteria.
Usually bearing temperatures slowly rise as the operation began, 1-2 hours to stabilize. Spherical roller bearings normal temperature for heat capacity, heat dissipation, speed of the machine and load another. If lubrication, installation is not appropriate, the NSK bearing temperature can rise dramatically, and abnormal high temperature occurs, in which case you must stop and take the necessary precautions.
