High Temperature Bearings 280°C (HT2)

High-temperature bearings rated at 280°C (HT2) are special industrial bearings designed by GMW to operate in extremely high-temperature environments, up to approximately 280°C.

At this temperature, HT2 operates with a perfect lubrication solution thanks to the addition of a special Teflon grease, allowing it to operate smoothly and reliably due to its unique lubricating fluid.

The suffix HT2 high-temp deep groove ball bearings offer the following advantages:

• Temperature capability: up to 280°C maximum 
• Low-speed operation: designed mainly for slow-rotation applications
• Material: Made from chromium steel material
• C5 clearance design compensates for temperature-induced distortion
• Surface coating: Manganese phosphate coating (according to EN ISO 9717) for corrosion protection and wear resistance
• Lubrication: Special polytetrafluoroethylene (PTFE) heat-resistant grease for smooth movement

Available Configurations HT2 bearings usually come in two versions:

• Open type (no shield)
• ZZ type – two heat-resistant steel shields.

Typical Industrial Applications:

The Suffix HT2 bearings are widely used in high-temperature industrial processes, such as

• Brick kiln carts
• Ceramic furnaces
• Glass manufacturing lines
• Steel rolling conveyors
• Die-casting machine and aluminum furnace
• Etc…
