Beirun specializes in custom slewing bearing solutions for truck cranes and other industrial equipment. Through engineering assessment, precise measurement, and customized manufacturing, we help customers find reliable replacement solutions when original components are damaged or difficult to source.
In May 2026, the slewing bearing of a truck crane was damaged during operation. The original manufacturer’s spare parts involved a long procurement lead time and high costs, so the customer contacted Beirun to explore an alternative solution.
After evaluating the customer’s requirements, our engineering team carried out on-site measurements and reassessed the key technical parameters of the damaged component. Based on the measurement results and operating conditions, we designed and manufactured a customized 131.25.2555 three-row roller slewing bearing.
Our custom slewing bearing solution was developed based on the damaged component’s dimensions and the truck crane’s operating requirements.
From measurement and design to manufacturing, delivery, and installation, the entire process took just 38 days, helping the customer restore the equipment to operation promptly.
On-Site Measurement and Design Revalidation
The first step was to inspect the damaged slewing bearing and obtain accurate measurements of the existing component.
Because the original bearing had been deformed and damaged, simply replacing it with a standard product was not an appropriate solution without further technical evaluation. Our engineering team assessed the actual operating conditions of the truck crane and rechecked the critical dimensions and design parameters.
These included the raceway pitch-circle diameter of 2,555 mm, roller specifications, and gear tooth parameters. The team used the measurement results to verify the relevant design requirements and develop a customized replacement solution.
This engineering-led approach helped ensure that the replacement slewing bearing was designed around the customer’s actual equipment requirements rather than relying solely on a standard catalog specification.
For customers facing long spare-parts lead times or difficulties sourcing original components, Beirun can evaluate customized slewing bearing solutions based on available drawings, dimensional measurements, and application requirements.
Customized Manufacturing of a Three-Row Roller Slewing Bearing
Following the engineering assessment, Beirun proceeded with the manufacture of the customized 131.25.2555 three-row roller slewing bearing.
A custom slewing bearing must be designed and manufactured with careful attention to the relevant dimensions, raceway configuration, rolling elements, and gear specifications. These parameters are important when developing a replacement component for existing industrial equipment.
By coordinating engineering review and manufacturing, Beirun worked to meet the project’s technical requirements and delivery schedule.
Each custom slewing bearing project requires careful review of dimensional compatibility, gear specifications, and application requirements.
Our approach focuses on practical, application-specific solutions for customers who need replacement components tailored to their equipment. Depending on the project, technical evaluation can be based on existing component measurements, engineering drawings, and operating requirements.
Delivery and Installation in 38 Days
One of the main challenges in this project was the procurement lead time associated with the original manufacturer’s spare parts. A prolonged wait could delay the return of the truck crane to service.
Beirun coordinated the measurement, design, manufacturing, delivery, and installation process to help address the customer’s needs within a compressed schedule.
The complete process took 38 days. The customized slewing bearing provided an alternative to the original spare-part procurement route and helped the customer restore the equipment to operation promptly.
This project demonstrates the value of responsive engineering support and customized manufacturing when standard replacement options are costly or difficult to obtain within the required timeframe.
