Superior High-Temperature Stability: Utilizes heat-resistant steel or materials with optimized heat treatment; maintains excellent dimensional stability at high temperatures; minimizes operational deviations caused by thermal deformation.
High-Temperature Lubrication: Offers high-temperature grease options; suitable for long-term operation with reduced re-lubrication frequency; resists rapid loss or carbonization at elevated temperatures.
Smoother Operation: Reduces noise and vibration under high-temperature conditions; ideal for equipment requiring high stability; extends the maintenance interval for the entire machine.
Customizable to Operating Conditions: Available with various sealing configurations; accommodates different internal clearance requirements; solutions can be tailored based on speed, temperature, and load.

The exact specification should be determined according to the application rather than temperature alone.

High Temperature Bearings are suitable for equipment operating under elevated temperatures, including:
· Industrial Ovens & Kilns:For conveyor and rotating components exposed to high temperatures.
· Heat Treatment Equipment :Used in heating, annealing, and other thermal processing equipment.
· High-Temperature Conveyors : Suitable for rollers and rotating parts in hot production environments.
· Fans & Blowers : Used in ventilation and air-moving equipment operating in high-temperature conditions.
· Ceramic Processing Equipment :Suitable for rotating components exposed to heat during ceramic and refractory processing.
· Other Industrial Machinery :BMT Bearings can recommend suitable configurations based on temperature, speed, load, and lubrication requirements.
First, identify the equipment's normal operating temperature and the maximum temperature likely to be encountered. Distinguish between continuous operating temperatures and short-term peak temperatures to select appropriate bearing materials and lubrication schemes.
When high temperatures and high speeds occur simultaneously, internal friction and heat generation within the bearing increase. Factors such as grease performance, internal clearance, cage structure, and bearing precision class must be comprehensively evaluated to ensure stable operation.
Determine whether the bearing will primarily withstand radial loads, axial loads, or combined radial and axial loads based on the equipment's actual operating forces. Additionally, the magnitude of the load directly influences the choice of bearing specifications and its service life.
The lubricant must maintain effective lubricating properties across the expected temperature range.
During high-temperature operation, the shaft, bearing housing, fit clearances, and internal clearances are all affected by thermal expansion. Therefore, the entire assembly system must be considered holistically to prevent clearance fluctuations or operational irregularities as the equipment heats up.
Even if the High Temperature Bearing itself is heat-resistant, contaminants such as dust, powders, water vapor, chemical agents, and process particles can significantly reduce its service life. Appropriate sealing or dust-protection mechanisms should be selected based on the operating environment.
BMT Bearings has specialized in bearing manufacturing since 2004, offering both standard and customized bearings backed by more than twenty years of industry experience.
We utilize automated grinding and assembly processes to ensure dimensional consistency, boost production efficiency, and guarantee reliable delivery.
Selecting high-temperature bearings requires considering more than just temperature. BMT Bearings evaluates a comprehensive range of factors—including operating speed, load, internal clearance, lubrication, sealing, shaft fit, housing conditions, and other operating parameters—to provide optimal bearing solutions.
BMT Bearings accommodates OEM and custom bearing requirements. We can evaluate projects based on technical drawings, samples, bearing part numbers, or detailed application specifications.
Depending on the bearing type and customer requirements, our inspection protocols cover dimensional checks, hardness testing, vibration analysis, noise testing, and other quality control measures.

The allowable temperature depends on the bearing structure, material, grease, seal, internal clearance, speed, load, and operating conditions. Customers should provide the continuous and peak operating temperatures so the appropriate configuration can be evaluated.
Not necessarily. Thermal expansion needs to be considered, but the appropriate internal clearance depends on the shaft and housing fits, temperature difference, bearing size, speed, and operating conditions.
The main differences lie in the materials, grease, cages, and internal clearance control. Standard bearings are more prone to lubrication failure and reduced service life at high temperatures.
The most useful information includes the bearing number or dimensions, operating temperature, rotational speed, load, lubrication method, sealing requirements, shaft and housing information, and application.
Yes. BMT Bearings can evaluate non-standard bearing requirements based on drawings, samples, existing bearing numbers, or detailed application parameters.
