High-Temperature Deep Groove Bearings
-- Steady & Reliable Manufacturer --
Introduction to High-Heat Endurance Ball Bearings
In industrial processes like baking, drying, and metallurgy, standard bearings quickly fail due to grease breakdown and material softening. Our High-Temperature Deep Groove Bearings are specifically engineered to operate reliably in environments up to 350∘C (662∘F). They feature specialized high-carbon chromium steel, optimized radial internal clearance (C4 or C5), and solid lubricants like graphite or advanced high-temperature grease. This design eliminates issues like cage creep and lubricant evaporation, ensuring smooth, extended operation in ovens, kilns, and smelters.

Technical Parameters for Extreme Heat
| Feature | Technical Requirement | NSB Advantage/Design |
|---|---|---|
| Operating Temperature | Continuous use up to 350∘C | Materials and heat treatment are stabilized to maintain hardness at elevated temperatures. |
| Internal Clearance | High Radial Clearance (C4/C5) | Mandatory C4 or C5 clearance to compensate for extreme thermal expansion of the shaft and housing. |
| Lubrication | Solid Graphite or High-Temperature Fluorinated Grease | Specialized, low-evaporation solid or synthetic lubricants that do not carbonize at high heat. |
| Cage Material | Stamped Steel or No Cage (Full Complement) | Avoids polymer or brass, which would soften; full complement allows maximum load but lower speed. |
| Radial and Axial Load | Reduced Dynamic Load Rating | Load capacity is derated due to reduced material hardness at high temperature, requiring careful selection. |
Common High-Temperature Applications
-
Industrial Ovens and Dryers: Bearings for kiln cars, furnace conveyor rollers, and paint curing ovens.
-
Food Processing: Commercial baking equipment, dough mixers, and high-heat sterilization chambers.
-
Metallurgy: Cooling beds and rolling mill equipment where heat dissipation is limited.
-
Exhaust and Boiler Fans: Motor and fan support exposed to extreme exhaust heat.
Advantages in Thermal Environments
- Reliable Operation at Extreme Heat:
Withstands temperatures that would destroy conventional bearings and lubricants, maintaining structural integrity and hardness.
- Eliminates Lubrication Issues:
Solid lubrication provides lifetime operation without re-greasing, preventing costly manual maintenance cycles in inaccessible high-heat zones.
- Minimized Thermal Stress:
Specific C4/C5 clearance prevents internal binding and premature failure caused by differential thermal expansion.
- Corrosion Resistance:
Treated steel and specialized coatings resist high-temperature oxidation and scaling.
