Custom slewing bearings for mining, amusement,
construction and new energy equipment.
Our slewing rings are widely used in mining machines, Ferris wheels, construction machinery and wind power units. Strict production standards guarantee reliable performance under heavy load.
Custom slewing bearing for various rotary equipment
We support non-standard customization, size optimization and sample trial production. Reliable quality and responsive after sales help long-term cooperation with global equipment manufacturers.
We provide customized slewing bearing solutions for marine, amusement, new energy & mining projects worldwide. Below are our representative finished cooperation cases.
Our underwater pipelaying vessel suffered severe seawater corrosion and frequent rotating stuck issues. After adopting their customized marine anti-corrosion slewing rings, the equipment runs stably for 18 consecutive months with zero breakdown, satisfying our long-term offshore operation requirement.
The sightseeing Ferris wheel needs all-year-round stable heavy-load operation. Their low-noise high-stability slewing bearings greatly cut our annual maintenance cost by 40%, and no abnormal vibration complaints from visitors ever since installation.
Our solar tracking brackets work under huge temperature difference and frequent sandstorm on inland Anatolia plateau. Specially sealed & wear-resistant slewing parts effectively avoid sand jam, improving overall power generation efficiency by about 8%.
Professional tech sharing covering slewing ring selection, installation, maintenance and field application solutions.
Marked soft annealing zone on slewing ring must be arranged at zero-load idle position away from main bearing force direction. Adopt diagonal cross tightening for mounting bolts and guarantee flat installation base to avoid eccentric wear.
