Description Shipping Information Returns

The NSK NAS15ALSZ is a stainless-steel precision linear guide block engineered for advanced linear motion applications where corrosion resistance, durability, and high positional accuracy are essential. As part of NSK’s NS Series, this carriage incorporates a four-row recirculating ball mechanism, delivering low-friction movement, high rigidity, and stable performance under significant dynamic and static loads.

Constructed from stainless steel, the NAS15ALSZ offers enhanced resistance to moisture, chemicals, and harsh operating environments, making it ideal for cleanrooms, food processing, medical devices, and applications where corrosion protection is critical. The “Z” light preload classification removes internal clearance, improving stiffness and ensuring reliable repeatability in high-precision operations.

Technical Characteristics

  • Series: NS Series Linear Guide

  • Carriage Type: NAS – Stainless Steel (ALS designation)

  • Material: Stainless steel body and raceways for maximum corrosion resistance

  • Rail Size: 15 mm nominal width

  • Preload Class: Z (Light Preload) – Increased rigidity and zero-clearance motion

  • Running System: Four-row recirculating ball bearing design

  • Load Rating:

    • Dynamic Load Capacity: Optimised for medium-to-high duty stainless steel linear systems

    • Static Load Capacity: Suitable for demanding industrial and environmental conditions

  • Mounting: Four top-mounted metric threaded holes

  • Precision: Manufactured to NSK’s high-accuracy tolerances for smooth, repeatable linear motion

  • Sealing: Integrated end seals to prevent ingress of contaminants
