THK SHS35V Linear Motion Guide
The THK SHS35V is a high-performance, compact flange-type linear motion guide from THK's SHS caged-ball series. As a standard-length block with mounting bolts accessible from above only, it features a narrower width for space-saving installation. Engineered with a 4-row, 45° contact angle design, it delivers equal load capacity in all directions, ensuring exceptional rigidity, precision, and smooth, maintenance-free operation for heavy-duty precision machinery.
Product Overview
The THK SHS35V is a high-performance, compact flange-type linear motion guide from THK’s SHS caged-ball series. As a standard-length block with mounting bolts accessible from above only, it features a narrower width for space-saving installation.

Core Official Features (From THK Website)
- 4‑Way Equal Load Capacity: Four rows of balls at a 45° contact angle provide uniform rated loads in radial, reverse-radial, and lateral directions, suitable for any mounting orientation.
- Caged Ball Design: Exclusive ball retainer eliminates metal‑to‑metal contact between balls, reducing friction, noise, and heat for long‑term maintenance‑free performance.
- Self‑Adjusting Capability: Unique DF (double‑face) arc‑groove design automatically compensates for minor installation surface errors, ensuring smooth, stable motion.
- High Rigidity & Precision: Optimized structure maintains high accuracy and rigidity under heavy fluctuating loads.
- Compact Flange (V‑Type): Narrow flange block with top‑mounted bolt holes ideal for space-constrained assemblies.
- Wide Temperature Range: Operates from ‑15°C to 80°C (5°F to 176°F).
- Global Standard Dimensions: Interchangeable with world-standard linear guide dimensions.
