The High Temperature Linear Guide is a stainless steel linear guide specifically engineered for high-temperature thermal environments. In such conditions, conventional linear guides commonly suffer from plastic retainer deformation, lubricant carbonization, and loss of preload.
Our High Temperature Linear Guide can operate continuously at temperatures up to 150°C, or withstand transient exposure up to 200°C, while maintaining stable performance and emitting zero outgassing.
Primary Application Areas: Semiconductor diffusion furnaces, vacuum deposition chambers, industrial oven automation, battery sintering lines, and heat treatment material handling systems.
Product Features
To meet the needs of your specific application scenarios, JSM offers integrated multi-product solutions. This series of high-temperature linear guides features high load capacity, long travel, and stable operation under elevated temperatures:
All-Metal Construction
Completely eliminates all plastic and rubber components (retainers, end caps, seals), preventing plastic aging, deformation, and outgassing issues at high temperatures.
High-Temperature Resistance
Capable of continuous operation at 150°C, with peak tolerance up to 200°C.
Zero Outgassing Design
Contains no plastic or rubber parts, making it suitable for vacuum environments and cleanroom applications.
High Rigidity
Multi-directional contact design provides uniform load distribution in axial, radial, and moment directions.
Smooth Operation
Factory-pre-lubricated with high-temperature grease to minimize component wear.
High Sealing Performance
Advanced internal sealing structure prevents ingress of dust, debris, and liquids.
Low Noise & Low Vibration
Ultra-smooth rail and block contact surfaces reduce operational vibration and noise.

Technical Advantages: Why Choose JSM High-Temperature Linear Guides
JSM high-temperature linear guides excel in extreme environments (high temperature, vacuum), making them particularly suitable for semiconductor manufacturing, heat treatment, and vacuum processes:
High-Temperature Resistance (150°C)
Martensitic stainless steel (440C equivalent) with through-hardening treatment; all-metal construction eliminates the risk of plastic component thermal deformation.
01
Material Stability
Low coefficient of thermal expansion combined with a stable crystalline structure; cryogenic treatment (-80°C) stabilizes retained austenite, preventing dimensional creep during thermal cycling.
02
Corrosion Resistance
440C stainless steel material with passivation treatment (ASTM A967); salt spray test (ASTM B117) resistance ≥ 72 hours.
03
High Precision Retention
CMM (coordinate measuring machine) inspection at 0.1μm precision; maintains JIS C3 grade (0.003mm/100mm) up to 120°C, transitioning to C5 grade (0.005mm) during continuous 150°C operation.
04
FEA-Optimized Design
Resonance frequency optimization ensures dynamically balanced operation.

Frequently Asked Questions
Lorem ipsum dolor sit amet,consectetur.
How does high temperature affect the load rating and service life of a linear guide?
+
-
At sustained temperatures above 100°C, the hardness of steel components may undergo slight changes, and thermal expansion alters internal preload. Our High Temp Series features specialized heat treatment and clearance adjustments to preserve nominal load ratings and long service life up to 150°C/200°C.
What type of lubricant is used in the High Temperature Linear Guide?
+
-
We apply premium synthetic high-temperature grease (PFPE / Fluorinated lubricants) designed not to carbonize or bleed off under thermal stress. Re-lubrication intervals should be based on operating temperature levels and cycle times.
Can these guides operate in cleanroom high-temperature environments?
+
-
Yes. By pairing stainless steel construction with low-outgassing high-temperature vacuum grease, these linear guides can be customized for cleanroom and vacuum thermal chamber operations.
Is custom sizing or rail mounting available for high-temp environments?
+
-
Yes. As an OEM manufacturer, Zhejiang Jinshanmen Transmission Technology Co., Ltd. provides customized rail lengths, surface treatments, special clearances, and custom mounting hole pitches tailored to your thermal equipment design.
