Maintenance & Protection

GREASING AND RE-GREASING

A suitable lubrication is essential for the longevity of the raceways and gears. Please fully grease the raceway based grease or equivalent grease before installation. The greasing frequency varies according to utilization and working environment. General, the lubrication interval we recommended is 150 hours. If under extreme working instruction, we would recommend re-greasing every 60 hours for ball type slewing ring, every 40 hours for roller type slewing ring. The frequency should be reduced when conditions of application are severe, such as high temperature, high humidity, dust and large temperature difference environment.

The operating conditions such as loads, temperatures, speeds, vibrations, etc... determine the lubrication interval.

• Greasing is required before and after a long non-operation period.

• Slowly rotate the bearing while greasing the raceway.

• During cleaning prior to re-greasing the gear, check carefully for any foreign body at the tooth root ring and pinion. Check the even load distribution of the pinion on the entire width of the ring gear and correct alignment of the axes if needed. Check the backlash of the pinion and ring gear.

RACEWAY

Standard grease: Mobilux EP2 or equivalent

Unless otherwise specified, the slewing rings are delivered greased.

GEAR

A protection against oxidation is applied

GREASING HOLES

Radially or facially located, depending on design, these holes are generally tapped M10 x pitch. 1.00 and closed by plastic caps or Hc screws. Remove these plugs before fitting the slewing ring with grease nipples or linked to a centralized lubrication system.

Caution :

The filler plug for the rolling elements has a blind tapped hole which is not a greasing hole.

REGREASING METHODS

Whenever the application allows it, greasing must be carried out during rotation at slow speed, on two revolutions minimum, through all the greasing holes.
