UK Construction Parts can help if you are in need of a new swing slew bearing.  But did you know more than 90 percent of slewing ring failures can be avoided if machine owners simply perform a few simple maintenance tips?

Some of the suggestions may seem like common sense but its worth taking a look.

Grease regularly : Apply a lot of extreme-pressure grease to the fittings around the bearing where the machine’s service manual instructs you to.

Purge with grease : Pump grease into the bearing until you see old grease squeeze past the seal. This will help push debris out of the bearing.

Inspect the grease : Rub some of the purged grease. If you see or feel grit or metal chips in it, you may have a bearing problem.

Do not overload :  Do not push your loads over the limit.  A depression of even 1/1000 on the swing bearing will eventually end up causing failure.

Avoid repetitive, heavy loads : Lifting with the boom and undercarriage in the same position can put a dimple in the bearing race close to the uneven load.  If possible, change the angle as often as possible.

Predict failure and repair the bearing : If the turning torque of the bearing increases substantially, or if you notice a clicking or grinding noise when rotating, grease the unit and have some of the purged lubricant analysed for metal debris.

Play can indicate a problem and will show up as a lack of stiffness in the extended boom. Free play magnified over the length of the boom allows it to rock back and forth under load. Check bearing clearance with a dial indicator that measures how much the structure tilts when the boom is loaded.

No matter how much you inspect your swing bearing, it’s eventually going to wear out.  However, maintaining the part could be the difference between getting yours rebuilt or spending the money on a new one.  When it is time to replace your swing bearing, give UK Construction Parts a call.  We have high quality branded swing bearings in available for prices way less than what you will pay for a new Genuine swing  bearing.
