A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official PYG website offers S55C linear guides cut to length and describes rail production and joined long-rail supply; the company page lists linear motion component R&D and production in Haiyan, Zhejiang. Check rail series, matching carriages, mounting holes and joint requirements; a single rail does not replace a complete drive module.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The rail is available in hardened steel or stainless steel. The standard rail material is bearing steel GCr15 per GB/T 18254, with hardness 58-62 HRC per ISO 683-17. Stainless steel is optional for corrosion resistance.
Shaft diameters range from 8 to 80 mm, and rail lengths from 100 to 4000 mm. Dynamic load rating is 0.5-120 kN, static load rating 1-160 kN, based on ISO 14728-1. These are reference ranges; confirm for your specific model.
Travel accuracy grades C3 (high precision) and C5 (general use) per ISO 10285. Repeatability is ±0.005 to ±0.02 mm. Verify the required grade for your application.
Maximum travel speed is 2-5 m/s, operating temperature -20 to 80 °C, and vibration amplitude ≤0.05 mm at 1 m/s and 50% load. Lubrication is grease (lithium soap) with optional oil; contact seals for dust protection. Always check with the manufacturer for specific conditions.
