As a leading manufacturer with a decade of expertise, Henan San Kuang Machinery Technology Co., Ltd. is proud to present our specialized line of High Temperature Resistant Ball Bearings & Spherical Roller Bearings. Engineered specifically for the demanding environments of industrial ovens, furnaces, and other high-heat applications, these bearings are the result of our commitment to innovation and reliability, backed by our ISO 9001 certified quality management system. Operating from our expansive 10,000-30,000 square meter facility in Luoyang, we combine advanced manufacturing with rigorous testing to deliver components that ensure your thermal processing equipment runs smoothly, efficiently, and with minimal downtime.
Our high-temperature bearings are designed to withstand the extreme conditions that cause standard bearings to fail prematurely. They are a critical upgrade for any industrial heating system, providing enhanced durability and operational stability.
- Superior Heat Resistance: Manufactured from specially selected and heat-treated alloy steels, our bearings maintain structural integrity and dimensional stability at elevated temperatures far beyond the limits of standard bearings.
- Optimized Lubrication Systems: We offer bearings pre-lubricated with specialized high-temperature greases or configured for solid lubricants. This ensures continuous lubrication film integrity, reducing friction and wear even in environments where conventional lubricants would degrade or carbonize.
- Robust Sealing Solutions: Optional high-temperature seals (such as fluoropolymer or metal shields) are available to protect the bearing internals from process contaminants like dust, ash, or chemical vapors, extending service life.
- Enhanced Load Capacity & Misalignment Tolerance: The inclusion of Spherical Roller Bearings in our product line is crucial. Their self-aligning capability accommodates shaft misalignment and housing deflections common in large oven structures, while their design supports heavy radial loads and moderate axial loads.
- Precision Engineering for Smooth Operation: Our ball bearings provide high-speed capability with low friction, ideal for fan shafts, conveyor rollers, or circulating systems within the oven where precise, smooth rotation is essential.
The technical specifications below outline the core parameters of our standard offerings. Custom configurations in dimensions, lubrication, and sealing are available upon request to meet your specific oven design.
| Parameter | Ball Bearing (Typical) | Spherical Roller Bearing (Typical) |
|---|---|---|
| Operating Temperature Range | Up to 350°C (662°F) with special lubrication | Up to 250°C (482°F) standard; higher available |
| Primary Load Direction | Radial and light axial | High radial, moderate axial |
| Key Advantage | High-speed, low friction operation | Self-alignment, high load capacity |
| Common Sizes (Bore) | 10mm - 100mm | 25mm - 150mm |
| Sealing Options | Metal shields, high-temp rubber seals | Labyrinth seals, steel flingers |
Choosing our high-temperature resistant bearings translates into direct benefits for your operation:
- Extended Maintenance Intervals: Reduced bearing failure rates mean less frequent shutdowns for replacement, increasing overall equipment availability and productivity.
- Improved Process Consistency: Reliable bearing performance ensures consistent speed for fans and conveyors, leading to uniform heat distribution and product quality in your oven.
- Reduced Total Cost of Ownership: While the initial investment might be higher than standard bearings, the dramatic increase in service life and reduction in unplanned downtime result in significant long-term savings.
- Enhanced Safety: Preventing catastrophic bearing seizure in high-temperature environments mitigates the risk of secondary damage or safety hazards.

Frequently Asked Questions (FAQ)
Q1: What is the maximum continuous operating temperature for these bearings?
A: The maximum temperature depends on the bearing type and lubrication. Our ball bearings can operate continuously up to 350°C with special high-temp grease, while standard spherical roller bearings are typically rated for up to 250°C. For applications exceeding these ranges, customized solutions are available.
Q2: Can these bearings handle both radial and axial loads in an oven?
A: Yes, but the capacity varies. Ball bearings are suitable for combined radial and light axial loads, often found on fan shafts. Spherical roller bearings are excellent for high radial loads and can accommodate moderate axial loads, making them ideal for heavy conveyor rollers or support rollers.
Q3: How do you prevent lubricant failure at high temperatures?
A: We use advanced lubricants specifically formulated for high-temperature stability, such as synthetic hydrocarbon or polyurea-based greases. For extreme temperatures, we can supply bearings designed for solid lubricants like graphite or molybdenum disulfide, which do not liquefy or evaporate.
Q4: Are custom sizes or special configurations available?
A: Absolutely. As a manufacturer with our own factory, we offer customization for bore size, outer diameter, width, lubrication type, and sealing arrangements to fit your specific oven design and assembly requirements.
Q5: What is the typical lead time for orders?
A: Lead time depends on order quantity and specification. For standard catalog items, we can often ship quickly from stock. For custom-engineered bearings, our team will provide a precise timeline upon reviewing your specifications.
Q6: Do you provide any technical support for bearing selection or installation?
A: Yes, our engineering team can assist you in selecting the most appropriate bearing type, size, and configuration based on your oven's operating temperature, load, speed, and environmental conditions to ensure optimal performance.
Q7: What ports do you ship from, and what are your main export markets?
A: We primarily ship from the Port of Shanghai, Qingdao, Lianyungang, and Tianjin. Our main markets include North America, South America, Eastern and Western Europe, Southeast Asia, Africa, and the Middle East, demonstrating our global reach and export expertise.
Q8: How does the self-aligning feature of spherical roller bearings benefit oven applications?
A: Industrial ovens can experience thermal expansion and structural flexing, leading to shaft misalignment. The spherical roller bearing's self-aligning design compensates for this misalignment, preventing edge loading, reducing stress, and significantly extending bearing life under such conditions.
