Slewing bearings are widely used in hoisting machinery mining machinery construction machinery port ship machine and high precision of the radar of large rotary machinery and equipment, including guide launcher device at the same time, can also according to customer's specific requirements on the design development and production of various kinds of special structure of slewing ring bearings due to heart parts adopting rotary supporting bearing, thus tilting moment and axial force under radial force in the form a lot, but the structure of basic same slewing bearing cage with monolithic sectional isolation block structure, etc The integral type and segment type retainer are made of no. 20 steel or ZL102 cast aluminum alloy. The isolation block is made of polyamide 1010 resin
At a glance: six steps to save slewing ring bearings More than 96% of slewing ring failure could be avoided by following simple maintenance tips. Grease regularly. Apply a liberal shot of extreme-pressure grease to the fittings around the bearing's circumference at intervals recommended in the operator's manual. Purge with grease. Pump grease into the bearing until you see old grease squeeze past the seal. Purged grease can help carry any contaminants out of the bearing. Inspect the grease. Rub some of the purged grease between your thumb and forefinger. If you see or feel grit or metal chips in it, there may be a bearing problem. Honor load charts. Even slight overloads can dimple the bearing race. One 1/1000 of an inch depression will worsen with subsequent loads and cause eventual failure. Avoid repetitive, heavy loads. Lifting with the boom and undercarriage in the same position, such as repetitive curbside digging with an excavator, can put a dimple in the bearing race close to the uneven load. If possible, change the angle of approach from job to job. 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 the structure, grease the unit and have some of the purged lubricant analyzed for wear metals. Xuzhou Wanda Slewing Bearing Co.,Ltd. is a professional slewing bearing manufacturer. We have strict quality control system in our own factory,meanwhile, we have passed ISO9001:2008 Quality System Certification, certificates of Bureau Veritas and China Classification Society . In order to ensure the quality, we purchase best quality raw material, use advanced production equipment and technology and conduct strict quality control.
