Offshore cranes often work intermittently and are in starting, braking, forward or backward status. Continuously working with heavy load and under seawater or dust environment requires the cranes to have high efficiency, good stability, excellent reliability, long service life, and easy maintenance, which also needs the crane bearings to have high reliability and long lifespan.
LYJW can provide slewing rings for gear box, travelling mechanism, hoisting mechanism, luffing mechanism, and slewing unit in offshore and marine application.

LYJW’s professional team has capabilities of fulfilling your requirements by providing customized slewing bearings.
After rough turning, the workpiece is detected by an ultrasonic flaw detector to examine cracks or other flaws and ensure the bearing’s stable quality and normal service life. Quenching and tempering can be conducted according to the requirements, to improve the strength and fatigue resistance of the material.
To ensure consistent quality control, we have applied a series of specific and strict measures across all areas of our company. As a high-tech enterprise, our products have passed ISO9001-2000 quality system certification, CCS, ABS, BV, GL and other certifications, and have obtained a number of patent certificates.
We offer both standard and custom bearings tailored to our customers’ specific requirements. After a thorough examination of the bearing condition, size, bearing tooth parameters and any other special processes prescribed by the customer, we will then recommend the most suitable model. To ensure the customer's satisfaction, we also provide detailed diagrams, three-dimensional drawings, and load curves to confirm.
