Proper Slew Ring Maintenance for Longer Service

Slew ring is generally designed for lifting equipment that requires rotation. They are usually found in cranes, excavators, shovels, tunnel boring machines, and bucket trucks on bearings and gears.

If they are not maintained properly they can lead to premature failure. Slew ring is very expensive, so it should be checked regularly if the equipment is constantly in use. You can get best quality crane parts via

The check-up includes lubrication raceway, check the torque on the bolts, and lubrication equipment.

Bearing lubrication

Lubricating bearings is a slow process as part never, ever clumps should be oiled. So, when you are lubricating bearings important to rotate the equipment oscillates slowly to allow the oil to penetrate into all the gardens.

Heavy equipment such as backhoes, excavators and cranes that do use application oscillating all the time should be lubricated occasionally but, trenchers and boring machines that use oscillatory applications at all times should be lubricated every day to ease the friction.

Lubricants are not only made of metal-free of friction, but it also helps in the cleaning process. When the oscillation is playing application while applying grease, fat penetrates all the gardens keep fresh for the old oil through the seal.


Gear lubrication

Gears have slewed the ring. Hey differ from bearings, but the effect is the same. N tooth groove pattern is very different from the pads.

Dental squeeze lubricant so that the teeth should be lubricated every eight hours. The procedure to apply grease remains the same. Play equipment while applying a lubricant to allow penetration into the groove.


Bolts should not be left in the care check-up. This is a precautionary measure, but you can check them every few months, depending on how long they have been used.

The constant vibration can loosen bolts. Mounting bolts should be torqued to the proper level and checked regularly to ensure correct pre-tension.

Bolts not properly pre-tensioned can fail, causing damage to the equipment and, more importantly, injury to workers.
