Established in 1998, Luoyang Jiawei Bearing Manufacturing Co., Ltd. (LYJW) is a professional manufacturer of slewing bearings and we can design and manufacture single-row ball slewing ring bearing, double-row ball slewing ring bearing, three-row roller slewing bearing, ball-roller combination slewing ring, crossed roller bearing, crossed tapered roller bearing, slew drives and custom bearings.
By virtue of expertise team, advanced manufacturing technologies and strict quality management system, LYJW takes the lead in the R&D of slewing bearings and custom bearings, which are designed with reasonable construction, light weight, good load carrying capacity and high versatility. The bearings’ diameters range from 200 to 15000mm and the accuracy covers P0, P6 and P5 class. Our slewing bearings, slew drives, precision bearings and custom bearingsare widely used in construction, engineering, mining, marine, chemical, military, wind turbine, medical equipment, and many other industries.
In 2008, LYJW passed the ISO 9001-2015 Quality Management System Certification and actively explored overseas markets in that year, and exported our slewing ring bearings to Europe, America, Asia and many other countries and regions. In 2015, we passed CCS Certification and ABS Certification. Now, LYJW can manufacture CCS, ABS, BV, GL and other certified products.
LYJW provides a variety of high precision bearings including crossed roller bearing, robotic bearing, rotary table bearing, harmonic drive bearing. In order to meet different applications, these bearing products are available with various series:
- Crossed roller bearing: RB, RE, RU, RA, CRBC, CRBH, XSU, SX series
- YRT Rotary Table Bearing: YRT, YRTS, YRTM, ZKLDF series
- Crossed tapered roller bearing: XRT series
The bearings can be custom made with precision class of P5, P4, and P2, and inner diameter range from 10mm-1500mm. Featuring with high running accuracy, long service life, high load capacity, easy maintenance, and high rotational speed, our products are widely used for joints and rotating parts of industrial robots, rotating tables of CNC machining centers, precision rotary tables, medical equipment, measuring instruments, semiconductor manufacturing equipment, etc.
LYJW adheres to the business principle of “Quality and Integrity” and we will keep providing outstanding bearings and superior services to serve global customer.
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.
