With its profound technical expertise in high-end bearings, LTZC has become one of the world's leading manufacturers of slewing bearings, providing bearing products that meet high standards and serving customers worldwide.
LTZC's advantages extend beyond its precision manufacturing capabilities; it also includes providing comprehensive technical support and services to its customers, particularly in on-site measurement and problem-solving. By combining precise measurement techniques and leading manufacturing capabilities, LTZC provides customized and efficient solutions to help customers overcome various challenges encountered in practical use.
What is a Crane Slewing Bearing?
A slewing bearing is a core component used to support and rotate equipment, widely used in heavy machinery such as cranes, port machinery, and tunnel construction equipment. As a special type of bearing, slewing bearings can typically withstand high loads, heavy loads, and complex multi-directional forces simultaneously, making their design and manufacturing far more challenging than that of ordinary rolling bearings. Especially in equipment like cranes, the slewing bearing not only supports the rotating part of the equipment but also bears the vertical and horizontal loads generated during operation, thus requiring even stricter specifications.
Crane slewing bearings typically consist of inner and outer rings, rolling elements, and a gear ring, and are characterized by their ability to support large torques, high load capacity, and long-term operation. Their main function is to ensure the stable operation of the crane in high-load, high-frequency rotation environments. The size, material, and precision of the crane slewing bearing directly affect the equipment's working efficiency and service life; therefore, choosing the appropriate slewing ring is crucial for any crane equipment.
Common types of slewing bearings:
Four-point contact ball slewing bearing
Double-row roller slewing bearing
Crossed roller slewing bearing
Three-row cylindrical roller slewing bearing
What Problems Are Customers Encountering?
While providing slewing bearing solutions to global customers, the LTZC team frequently finds that some customers, particularly in Europe, encounter several common problems during use:
Inability to Accurately Measure Fitting Dimensions and Parameters
Slewing bearings involve complex structures and dimensions, including inner and outer rings, rolling elements, and gear rings. The size and design requirements of slewing bearings vary significantly depending on the type of crane, requiring very precise measurements to ensure the selected bearing perfectly fits the equipment. One of the biggest challenges many customers face is the lack of accurate measuring tools and the inability to perform accurate measurements of the bearing's fitting dimensions and key parameters. This directly affects the accuracy of selection and the normal operation of the equipment.
Bearing Wear and Corrosion Problems
Due to prolonged operation in harsh environments, many customers' slewing bearings experience severe wear and corrosion problems, leading to reduced equipment efficiency and even equipment failure and downtime. Although some customers try replacing the bearings, the lack of accurate dimensional data means the selected bearings may not perfectly match the equipment, potentially exacerbating wear problems and creating a vicious cycle.
Long Equipment Downtime
During maintenance and bearing replacement, customers often experience prolonged equipment downtime due to the inability to obtain the correct dimensional parameters in a timely manner, affecting project progress and overall efficiency. Delayed downtime not only results in direct economic losses but may also impact overall project planning and the customer's market competitiveness.
Lack of Effective Customized Solutions
Each crane and each project has unique requirements, and customers want tailored bearing solutions. However, the traditional bearing market often only offers standardized products, lacking the ability to respond precisely to specific needs. LTZC's customization capabilities have become a key factor in solving these customer problems.

What Bearing Solutions Does LTZC Offer?
To address the various challenges customers encounter in practical use, LTZC offers a comprehensive set of targeted on-site bearing measurement services. Through this service, LTZC helps customers accurately obtain equipment dimensional data, thereby providing them with the best bearing solutions.
On-site Measurement Service
LTZC engineers, equipped with professional measurement tools such as calipers, depth gauges, coordinate measuring machines, and angle gauges, will personally visit the customer's site to conduct detailed measurements of the slewing bearing parameters of the crane. Using professional measurement tools and techniques, LTZC can obtain the precise dimensions of the equipment's slewing ring bearing, including inner and outer ring dimensions, bearing fit dimensions, and gear ring accuracy. This data is crucial for ensuring correct selection.
Confirmation of Key Parameters
After on-site measurement, LTZC will confirm all key parameters. These parameters include not only the physical dimensions of the bearing but also the bearing's working load, speed, temperature, and environmental factors. Through this process, LTZC ensures that the provided bearings fully meet the customer's needs in actual operation and guarantee the long-term stable operation of the equipment.
Provision of Professional Drawings and Specifications
LTZC not only provides accurate measurement data but also provides customers with detailed bearing drawings and technical specifications on-site. Through precise bearing drawings, customers can gain a clearer understanding of the bearing's design characteristics and application scope, providing necessary reference information for subsequent slewing bearing installation, maintenance, and inspection.
On-site Re-measurement and Data Verification
After completing the measurement and design confirmation, LTZC will conduct on-site re-measurement to ensure the accuracy and reliability of the data. Re-measurement not only improves data accuracy but also helps customers compare different bearing options, ensuring that the final selected bearing meets all the needs of actual use. Technical communication and guidance are provided to the customer during the measurement process to ensure their full understanding of the measurement results.
