Sliding bearing – performance and selection

Bearing bearing grease can also be used to lubricate, grease should be considered in the choice of the following:
(1) bearing load, low speed, should be selected small grease cone penetration, contrary to select a large cone penetration. High Speed ​​Bearing Selection smaller cone penetration, mechanical stability good grease. Of particular note is the grease base oil viscosity is lower.
(2) Select the grease dropping point temperature is generally higher than 20-30 ℃, continuous operation at high temperatures, and be careful not to exceed the allowable temperature range grease.
(3) bearing water washout or humid work environment, good water resistance should be selected based calcium, aluminum or lithium grease.
(4) the choice of grease with good adhesion.
Sliding bearings with grease lubrication cycle:
Occasional work, important parts: shaft speed <200r / min, lubrication cycle once five days; shaft speed> 200r / min, lubrication cycle three days time.
Intermittent work: shaft speed <200r / min, lubrication cycle 2 days time; shaft speed> 200r / min, lubrication cycle 1 days.
Continuous work, working temperature less than 40 ℃: shaft speed <200r / min, lubrication cycle once one days; shaft speed> 200r / min, lubrication cycle once per shift. Continuous work, working temperature 40-100 ℃: shaft speed <200r / min, lubrication cycle once per shift; shaft speed> 200r / min, second class lubrication cycle.
