Slocable Both Ends Tapped Precision Linear Shaft Stainless Steel 8mmX200mm

  • High precision: With high-precision dimensional tolerance and geometric tolerance, it is widely used in various precision equipment, so you can use it with confidence..
  • Wide range of applications: Various chasing schemes can be selected to meet different use environments..
  • Wear-resistant: Usually used in conjunction with linear bearing products, it has excellent linear guiding function. Compared with the general shaft and bushing structure, even if it is high-speed reciprocating motion, it will not have great wear..
  • Rust prevention: hard chromium plated surface treatment can be selected, which not only has excellent rust prevention performance, but also the coating hardness has reached hv750. It will not be easily worn when matched with high hardness workpieces..
  • Good material: Bearing steel with excellent wear resistance (equivalent to SUJ2 and SUS440C) or equivalent high hardness corrosion-resistant steel are used for high-frequency quenching treatment to enhance wear resistance and maintain the original toughness..
