China 25mm Linear Guide Size Ser-gd25
The Ser-GD25 linear guide is a 25mm profile ball rail system designed for precision motion applications in automation and CNC machinery. It features a hardened steel rail with hardened steel ball bearings recirculating within a sealed carriage. The unit is part of a product line that includes sizes from 14mm to 45mm, indicating standard industrial compatibility. The guide is intended for use in applications requiring high rigidity and repeatable positioning under moderate to heavy loads.
The guide is manufactured using standard bearing steel with surface hardening to HRC58-62, consistent with DIN 645 or JIS B 1192 guidelines. The ball circuit is designed for low friction and high load capacity, with typical preload options of zero, light, or medium. Packaging is usually in individual plastic sleeves within cartons, with no mention of corrosion-resistant coating. Buyers should confirm whether the unit includes lubrication or requires pre-installation greasing.
This product is commonly purchased by manufacturers of CNC routers, 3D printers, packaging machinery, and automated assembly lines. End users prioritize smooth motion and minimal backlash. Trade terms are typically FOB Jinan or Qingdao, with lead times of 15 to 25 days. MOQ is not specified, but the supplier indicates interest in bulk orders and agent partnerships. Buyers should request dimensional drawings and load rating curves before placing orders.

Sourcing China 25mm Linear Guide Size Ser-gd25 from Shandong Sair Mechanical Guide Co., Ltd. - China Import Guide
Before ordering, confirm the exact preload class, rail hardness, and dimensional tolerances with the supplier. Request a certified dimensional drawing with critical dimensions: rail width, carriage height, and ball circle diameter. Verify that the unit matches the Ser-GD25 designation and not a similar model. Without these, installation may require custom machining or result in misalignment.
Logistics are typically FOB Jinan or Qingdao port, with lead times of 15 to 25 days. Packaging is in cardboard cartons with internal foam, but no anti-rust wrapping is mentioned. Buyers must confirm Incoterms, insurance coverage, and whether export documentation includes a material certificate. Payment terms are likely 30% advance, 70% against copy of B/L, but must be negotiated directly.
Quality inspection should include measurement of rail straightness, carriage smoothness, and ball recirculation. Request a sample unit for functional testing under load. Check for surface scratches, debris in the ball circuit, and proper sealing. Buyers should engage a third-party inspector to verify compliance with ISO 3408 or DIN 645 before full shipment.
