The linear plain bearings grease lubrication cycle:

By accident, linear plain bearings not important parts: shaft speed < 200 r/min, the lubrication cycle 5 days; Shaft speed > 200 r/min, the lubrication cycle 3 days.

Continuous work: shaft speed < 200 r/min, the lubrication cycle 2 days; Shaft speed > 200 r/min, the lubrication cycle 1 days.

Continuous work, operating temperature less than 40 ℃ : shaft speed < 200 r/min, the lubrication cycle 1 days; Shaft speed > 200 r/min, the lubrication cycle once per class.

Continuous work, operating temperature 40-100 ℃ : shaft speed < 200 r/min, the lubrication cycle per shift once; Shaft speed > 200 r/min, the lubrication cycle every second.

The journal as uniform close contact with mobile crane bearing, and must fit clearance.

Refers to the journal and sliding bearing contact area of the central Angle. Contact Angle is not too big nor too small. Contact Angle is too small will make sliding bearing pressure increases, serious when they make the sliding bearing produces large deformation, accelerate wear, shorten service life. Contact Angle is too big, can affect the formation of oil film, can't get good fluid lubrication.
