Precision Linear Bearings

Precision transmission experts from the "hometown of Chinese bearings" - as a leading enterprise in Shandong's bearing industry, Juyuan Bearing relies on 15 years of precision manufacturing experience to provide high-precision linear bearing solutions for global industrial automation, precision machine tools, medical equipment and other fields. Located in the core bearing production area of China, we integrate high-quality raw material supply chain and advanced testing technology to create reliable transmission components with "micrometer level precision" standards, helping high-end equipment achieve smooth and precise operation.

1. Micron level accuracy ensures smooth motion

• Guide rail processing: Using cold drawn precision optical axis (straightness ≤ 0.05mm/m) and high carbon chromium bearing steel (GCr15) inner ring, the surface roughness Ra of the raceway is controlled to be ≤ 0.1 μ m through ultra precision grinding process, and the uniformity of contact stress is improved by 40%, effectively reducing the vibration amplitude of equipment operation to below 0.01mm
• Clearance control: Following the ISO 15241 standard, C0/C2/C3 three-level radial clearance selection is provided, suitable for high-precision positioning (error ≤± 5 μ m) and high-speed motion scenarios (maximum speed 5m/s)
• Testing system: Each batch of products is double checked by a coordinate measuring instrument (accuracy ± 0.001mm) and a laser straightness tester, with a critical dimension qualification rate of 99.9%

2. Long life design, suitable for harsh working conditions

• Material strengthening: The inner ring surface is treated with carburizing and quenching (hardness ≥ 60HRC), which improves the wear resistance by 30%. It has passed the 10000 hour life cycle test (GB/T 24610), extending the service life by 20% compared to conventional products
• Lubrication optimization: Built in self-lubricating retainer (optional with lithium based grease or solid lubrication coating), supports wide temperature range operation from -40 ° C to+120 ° C, with a maintenance free cycle of up to 2 years (under normal working conditions)
• Dustproof design: Standard dual lip nitrile rubber seal (IP54 protection level), blocking ≥ 99.5% of 50 μ m dust particles and reducing the risk of failure caused by foreign object intrusion by 80%

3. Global worry free service network, cooperation with zero concerns

• Response speed: 24/7 multilingual customer service (English/German/Japanese), providing technical solutions within 4 hours and on-site support within 24 hours (mainly for overseas markets)
• Delivery capability: Three major bonded warehouses in North America, Europe, and Southeast Asia have over 500 standard models available, with delivery within 72 hours after placing an order; Customized products (such as extended guide rails and non-standard installation holes) can be quickly sampled in 2 weeks
• Quality commitment: We provide a 2-year warranty for non human damage, with a final guarantee
