Slewing Bearing lubrication

The slewing bearing should be lubricated at regular intervals, with a heavy-duty, extreme-pressure grease. Slowly rotating equipment or oscillating applications, such as backhoes, excavators, and cranes, should be relubricated about every 100 hours of operation. More frequent lubrication—every day or every eight hours—may be needed on rapidly moving or continuously rotating equipment such as trenchers and boring machines.

While adding grease, the slewing bearings should be rotated to spread the grease throughout, with enough grease added to purge the old grease out through the seals. This procedure helps to clean out contamination.

Over long periods of time, grease tends to dry out and condensation can form within a slewing bearing. Grease should therefore be introduced at least every six months, whether the equipment is operating or idle.

Gear lubrication

Most slewing bearings incorporate gear teeth and the gear lubrication requirements are not the same as for the slewing bearing. Because the meshing action of the teeth tends to squeeze out lubricant, the gears should be lubricated every eight hours on slow or intermittently rotating equipment, and more often on rapidly or continuously rotating equipment. Small amounts of grease should be introduced at the point of mesh between the gear and pinion.
