bearing lubricant in use supplementary and replacement industry 双列角接触球轴承|3056轴承-pg电子官方网站

a. grease supplement interval
due to increased mechanical action , aging and pollution filled bearing lubricating base configuration will gradually lose its lubricating properties. therefore , the need for lubrication rank constantly replenished and updated. interval due to the formation of the lubricant added to the bearing , the size and speed , etc., and generally need to supplement the working time interval grease .
in addition, when the temperature exceeds 70 ℃ lower bearing case , bearing temperature rise 15 ℃, then use complementary interval grease reduced by half.
sided enclosed bearing grease during manufacture has been loaded , "hrb" used in these products are standard grease, the operating temperature range of properties suitable for other applications as required and a corresponding amount of filling grease and bearing size , grease life in general can be more than bearing life , except for special occasions , without added grease .
b. lubricant replacement cycle
oil change intervals and oil due to different conditions , under normal circumstances , the operating temperature is 50 ℃, less good when dusty environments, replaced once a year , when the oil temperature reaches 100 ℃, to 3 months or less replaced once .
