SKF bearing grease selection

Selecting a SKF grease can be a delicate process. Poor lubrication accounts for more than 36% of premature bearing failures. If including contamination, this number rises to well above 50%. The importance of proper lubrication and cleanliness is self-evident in the determination of bearing life.

Expected bearing temperature 
continuously >100 °C (210 °F) 
LGHP 2 High temperature
Expected bearing temperature 
continuously >150 °C (300 °F), 
demands for radiation resistance
LGET 2 Extremely high  temperature
Low ambient –50 °C (–60 °F), 
expected bearing temperature 
<50 °C (120 °F)
LGLT 2 Low temperature
Shock loads, heavy loads, 
frequent start-up / shut-down
LGHB 2 High load

Biodegradable, demands for 
low toxicity
LGGB 2 Biodegradable

NOTE:
* rotational speed = rotational speed, r/min x 0.5 (D+d), mm. 
** for ball bearings, for roller bearings SRB/TRB/CARB rotational speed up to 210 000 and for CRB rotational speed up to 270.000. 
*** C/P = load ratio, where C = basic dynamic load rating, kN , and P = equivalent dynamic bearing load, kN.
