High temperature performance and exchange limit bearing grease

High temperature performance and exchange limit performance exchange limit bearing grease in this paper, the oil other oil was compared with the new oil viscosity change/s25 % less than 10 ~ 15%, the most appropriate acidification degradation, less than 10% of heterogeneous oil mixed with water volume ( volume) % 0. 2 below 0. The following may be use again after dehydration (2 也许) Part weight pentane insoluble molecular % % 1. NSK bearings starting friction is small, and the difference between the sliding friction control also small, promote the standardization and normalization in the world, good compatibility, can be used interchangeably between different brands. Below 0 0. Five below zero. 2 below 0. 9 the following additives (abrasion carbon dust Characteristics: solid particles) Mr Sedimentation value 10 ml/ml0. 1 the moisture, dust and other foreign bodies, total acid number KOHmg metal abrasion powder/g new oil additive to 2 ~ 3 times by high value ash % 0. 2 the following - - - In the ash iron % 0. 1 the following - - - High temperature bearing lubricating oil during the performance test frequency lubrication method tally of the rotation of the ordinary condition * bad rotating disc method of oil once every 6 months each year 1 time oiled, droplet oil supply method every 6 months once every 3 months 1 time cycle ( continue) Method of oil once every 9 months 1 ~ 3 months 1 * poor spinning conditions as shown below. NSK bearings starting friction is small, and the difference between the sliding friction control also small, promote the standardization and normalization in the world, good compatibility, can be used interchangeably between different brands. Moisture condensation, or mixed with obvious. The previous: high temperature resistant bearing damage or failure forms there are four main affection next article: hot! Hot! Hot! Chongqing bearing factory is really too hot!
