The choice of the Spherical roller bearings grease:

Load < 1 mpa, Spherical roller bearings shaft neck circumference speed below 1 m/s, the highest working temperature 75 ℃, choose 3 calcium base grease;
1-6.5 MPa, load speed shaft neck circumference of 0.5 5 m/s, the highest working temperature of 55 ℃, choose 2 calcium base grease;
Load > 6.5 MPa, Series radial ball bearings under the shaft neck circumference speed 0.5 m/s, the highest working temperature 75 ℃, choose 3 calcium base grease;
Load < 6.5 MPa, shaft neck circumference of 0.5 5 m/s speed, the highest working temperature 120 ℃, choose 2 lithium base grease;
Load > 6.5 MPa, under the shaft neck circumference speed 0.5 m/s, the highest working temperature 110 ℃, choose no. 2 - sodium calcium base grease;
Load, 1-6.5 MPa shaft neck circumference speed below 1 m/s, the highest working temperature is 50-100 ℃, choose 2 lithium base grease;
Load > 5 mpa shaft neck circumference speed 0.5 m/s, the highest working temperature 60 ℃, choose 2 calender fat;
In damp environment, temperature under the condition of 75-120 ℃, should consider to use calcium - sodium based grease grease. In damp environment, working temperature below 75 ℃, no 3 calcium base grease, can also be used aluminum base grease. Working temperature at 110-120 ℃, can use lithium base grease or barium base grease. Centralized lubrication, consistency to small.
