Maintenance, inspection, and abnormal handling of SKF bearings and damage measures



Maintenance, overhaul, and abnormal handling of SKF bearings

In order to maintain the original performance of SKF bearings in a good condition for as long as possible, maintenance, overhaul, and accident prevention are required to ensure the reliability of operation and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The contents include monitoring of operating conditions, replenishment or replacement of lubricants, and inspections for periodic disassembly.

Damage and countermeasures of SKF bearings

In general, if the SKF bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and cannot be used. This early damage, as opposed to fatigue life, limits the quality of what is known as a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.

Regarding the damage state of the SKF bearing, for example, the jam of the ferrule rim of the roller bearing, as a cause, the lubricant is insufficient, unsuitable, the defect of the oil supply structure, the foreign matter intrusion, the SKF bearing installation error, the shaft If the deflection is too large, there will be coincidences of these reasons.

Therefore, it is difficult to know the true cause of the damage by only investigating the SKF bearing damage. However, if you know the use of SKF bearings, the conditions of use, the structure around SKF bearings, and understand the situation before and after the accident, combined with the damage state of SKF bearings and several reasons, it can prevent similar accidents from happening again.

High-speed TIMKEN bearings for grease performance requirements



(1) Long service life can reduce maintenance costs and reduce friction consumption of TIMKEN bearings.
(2) Appropriate consistency, with better vibration damping function, can reduce the noise of high-speed TIMKEN bearings, and is conducive to environmental protection.

(3) The anti-oxidation performance is good. After the use time is long, the appearance color and pH of the grease change little, and there is no obvious oxidation phenomenon.

(4) The flow performance is good. Generally, the use temperature is between -25 degrees Celsius and 120 degrees Celsius. The starting torque is small, the running torque is low, the energy consumption is small, and the temperature change is small.

(5) It has strong rust prevention, salt spray resistance and good water resistance, and can be used in harsh working environments.

(6) The insulation grade is A, E, and B grades, and may not contain additives such as sulfur and chlorine.

(7) Good adaptability and high and low temperature performance.

(8) Lubricity and abrasion resistance are good, no oil, no drying, no emulsification, no loss, and the grease itself should not contain solids.
