📐 Arc length formula: Arc length = radius × angle (rad). Example: R500mm, 90° → arc length ≈ 785mm
The THK HCR15A curved guide rail (arc rail) enables smooth, precise circular or arc-shaped linear motion. It overcomes the limitation of standard linear rails by allowing loads to travel along a curved path with high rigidity and low friction. Perfect for rotary robots, circular worktables, curved conveyors, medical rotating equipment, and more.

Q1: Can the HCR15A curved rail be combined with straight rails to form an oval loop?
A: Yes. THK provides transition blocks (straight-to-curve adapters) for elliptical or racetrack circulation. Please provide your layout drawing.
Q2: What is the maximum speed for the curved guide rail? Q3: Do you offer installation services? Q4: Is the HCR15A curved rail in stock? Q5: What is the lubrication interval?
A: Recommended ≤ 1.5 m/s, depending on radius and load. For small radii (
A: We provide detailed drawings and video guides. On-site guidance can be arranged for large orders (subject to discussion).
A: Common radii (R500, R1000) with 90°/180° arcs and HCR15C blocks are usually in stock. Non-standard radii require 15–20 days for custom production.
A: Under normal conditions, lubricate every 6 months or 2000 km of travel. Shorten to 3 months in dusty environments.
