Introduction For slewing bearings operating in ultra-high temperature working environments, standard rubber seals often fail prematurely due to thermal aging, deformation and wear, which will cause grease leakage and contaminant ingress, shortening the whole service life of slewing rings. To solve this industry pain point, we implement professional steel sealing treatment for heavy-duty slewing bearings.

Learn our factory’s practical procedure for measuring radial clearance of large slewing bearings. See how overhead crane and dial indicator work together to guarantee precise bearing pre‑delivery inspection.   hy Radial Clearance Matters for Slewing Bearings Radial clearance is one of the most critical technical parameters for slewing bearings. Improper radial play will directly lead

Meta Description: Longwei custom‑manufactures heavy‑duty three‑row roller external gear slewing bearings for Australian mining. Watch our on‑site inspection video for raceway & rolling element quality verification. Mining equipment operates under extreme working conditions: heavy shock loads, continuous heavy‑duty rotation, dusty site environment, and high demand for load‑bearing capacity and structural stability. For large‑scale mining machinery,

Lightweight thin slewing bearings are widely used in filling machinery, automation equipment, solar trackers and small engineering machinery. In this workshop video, we show you our laser marking process for ultra-thin lightweight slewing rings.   We adopt non-contact laser engraving to print permanent nameplate data directly on the slewing bearing surface. Marked information includes model

Introduction High‑quality slewing bearings rely on standardized machining procedures starting from raw forging blanks. Rough turning is the first critical step to remove excess material, correct forging deformation and lay a stable foundation for subsequent finishing, heat treatment, gear processing and assembly. At Longwei, we strictly control every turning procedure to guarantee dimensional stability for

Among these critical components, slewing bearings play a vital role in

Large Size Slewing Bearing Packaging & Breakbulk Shipping Solution | Longwei Transmission Meta Description Oversized heavy-duty slewing rings have large dimensions and heavy weight. We adopt custom plywood wooden cases with reinforced steel frames and breakbulk vessel shipping for safe global transportation of large slew bearings.

  Precise dimension measurement is one of the most critical quality‑control steps for large‑size internal‑gear slewing bearings. Even tiny deviations on inner‑diameter and gear‑tooth parameters will lead to poor meshing, abnormal noise, shortened service life once the slewing bearing is fitted onto tower cranes, excavators, wind‑energy equipment and heavy‑duty machinery.</p> <p>At our Longwei Transmission factory,
