The precision grade ensures accurate and repeatable positioning, vital for automated machinery and sophisticated manufacturing processes.
Manufacturing Process Flow and Quality Assurance
The production of the WE Series Linear Guides WE15 WE20 Heavy Duty Linear Bearing Slides follows a meticulous process flow, ensuring superior quality and performance. Each stage is subject to stringent quality control measures to meet international standards.
Schematic Process Steps:
High-grade bearing steel (e.g., GCr15 equivalent to AISI 52100) is sourced from certified suppliers. Initial chemical composition and metallurgical inspections are performed to ensure compliance with ISO standards (e.g., ISO 683-17) for material purity and integrity. This material choice is crucial for the service life and performance.
The steel is forged to create the basic rail and block shapes, enhancing grain structure and mechanical properties. Rough machining then removes excess material, preparing components for precision operations.
Components undergo a precise heat treatment process, including hardening and tempering, to achieve the desired surface hardness (typically HRC 58-62) and core toughness. This treatment is critical for wear resistance and dynamic load capacity, adhering to standards like ASTM A295 for bearing steels.
Advanced multi-axis CNC machines are utilized for grinding the raceway grooves and mounting surfaces to extremely tight tolerances. This stage is paramount for achieving the specified precision grades (e.g., H, P, SP) and ensuring smooth, low-friction motion. Dimensional accuracy is continuously monitored.
For specific applications, such as in petrochemical or water supply & drainage, anti-corrosion surface treatments like hard chrome plating or black oxide coatings may be applied. These treatments enhance resistance to corrosive media, extending service life in harsh environments.
Bearing balls, end caps, and lubrication components are assembled in a cleanroom environment. Post-assembly, each linear guide undergoes comprehensive functional testing, including smooth operation, running accuracy, and preload verification, ensuring adherence to ISO 12090 and ANSI standards for linear motion rolling bearings. This guarantees a service life of many thousands of kilometers under rated load.
Finished products are carefully packaged to prevent damage during transit, often with protective coatings and anti-corrosion wrapping for long-term storage or international shipping.
Target industries benefiting from this robust manufacturing process and the inherent advantages of WE Series Linear Guides WE15 WE20 Heavy Duty Linear Bearing Slides include:
