The guide rod is typically made from hardened steel or stainless steel, while the bearing may use linear ball bearings or bronze bushings. The material grade for the bearing is often GCr15 (high-carbon chromium bearing steel) per GB/T 18254, but confirm with the manufacturer.
Key specifications include shaft diameter (20–50 mm), stroke length (100–500 mm), radial runout (0.01–0.03 mm), axial clearance (0.02–0.05 mm), maximum load (500–2000 N), operating temperature (-10 to 80 °C), surface hardness (58–62 HRC), and surface roughness (0.2–0.4 µm Ra). Always verify these with the supplier for your specific application.
The assembly requires grease lubrication, typically lithium-based grease per DIN 51825. Regular lubrication is necessary to reduce friction and prevent premature wear. Follow the manufacturer's recommendations for lubrication intervals and type.
Common signs include increased vibration, unusual noise, visible scoring on the rod, or loss of positioning accuracy. If the assembly operates beyond its maximum load or temperature range, premature wear may occur. Inspect regularly and replace if any of these signs appear.
