FH® Heat-Resistant Steel Sliding Rails | Heavy-Duty Industrial Linear Motion

Product Specification

In high-temperature, high-load industrial environments, conventional linear guides often suffer from lubricant failure, thermal expansion jamming, and material deformation. FH® Heat-Resistant Steel Sliding Rails were developed specifically to solve these critical challenges.

As a specialized manufacturer of industrial transmission components, FH® utilizes premium heat-resistant alloy steel as the base material. Combined with precision grinding processes and advanced surface treatment technologies, these sliding rails maintain low friction coefficients and high rigidity under extreme conditions—including high-temperature kilns, heat treatment equipment, glass machinery, and steel metallurgy applications. Beyond standard specifications, FH® offers fully customizable solutions to match your unique equipment layouts.

Key Advantages
1. Superior Thermal Stability

• Material: Manufactured from precipitation-hardening stainless steel and heat-resistant alloy steel, exhibiting exceptional creep resistance at elevated temperatures.
• Performance: Within the 600°C – 800°C operating range, hardness degradation is significantly lower than industry benchmarks, effectively preventing rail deformation caused by high heat.

2. Patented Solid Lubrication Technology

• Conventional greases carbonize and fail under high temperatures. FH® rails offer optional graphite-plugged carriages or MoS₂ (molybdenum disulfide) coatings for dry lubrication.
• This eliminates contamination caused by lubricant evaporation (ideal for cleanroom environments) and removes the need for frequent regreasing maintenance.

3. Exceptional Corrosion & Oxidation Resistance
Advanced passivation processes provide strong resistance to oxidation and spalling in high-temperature oxidizing atmospheres—including steam and corrosive gases—significantly extending service life.

4. High-Precision Guidance
Precision gap control design compensates for thermal expansion at elevated temperatures, ensuring C3 / C5 precision grades in both cold and hot states. This meets the positioning accuracy requirements of automated loading/unloading systems and high-temperature handling robots.

Industry Applications
1. Industrial Heat Treatment Furnaces

• Application: Charging and discharging systems for bogie hearth furnaces and roller hearth furnaces.
• Value: Directly withstands radiant heat inside furnaces without requiring water cooling, simplifying equipment design.

2. Glass & Ceramic Manufacturing

• Application: Conveyor rails in glass annealing lehrs and ceramic kilns.
