HZ-20 Boundary Lubricated Bearings Manufacturers

POM-Coated HZ-20 Boundary Lubricated Bearings for Simplified Maintenance

In the demanding world of industrial machinery, choosing the right bearing solution can significantly influence operational efficiency, cost management, and long-term reliability. HZ-20 boundary lubricated bearings are designed to address these challenges by combining advanced materials, thoughtful engineering, and a maintenance-friendly design. With a structure that incorporates a steel plate base, a sintered spherical bronze powder layer, and a modified polyoxymethylene (POM) surface embedded with oil storage pits, the HZ-20 series offers a robust and cost-effective replacement for traditional copper sleeves.

Engineering That Reduces Maintenance Effort
The POM surface layer of HZ-20 bearings plays a crucial role in minimizing maintenance requirements. Its oil storage pits allow for gradual, consistent lubrication release during operation, which extends intervals between re-lubrication cycles. This design is particularly beneficial in applications like rolling mills, where frequent refueling is time-consuming and costly. By reducing the need for manual intervention, HZ-20 bearings simplify replacement procedures and keep production lines running more efficiently.

SF2 boundary-lubricated bearings, which share a similar design philosophy, also utilize a layered construction to balance strength, wear resistance, and lubrication performance. Both the HZ-20 and SF2 series are well-suited for low-speed, medium-load applications at normal operating temperatures, making them versatile options across industries.

Industrial Applications and Performance Advantages
HZ-20 boundary lubricated bearings excel in sectors where operational consistency and cost control are top priorities. Their ability to replace traditional copper sleeves not only reduces upfront material costs but also prolongs service life through better wear resistance and improved lubrication retention. In machinery such as rolling mills, the reduced refueling frequency directly translates into labor savings and minimized downtime.

Beyond heavy industry, these bearings can be adapted to various mechanical systems that operate under steady loads and moderate speeds, including processing equipment, agricultural machinery, and certain transport systems. In each case, the design helps maintain performance stability even in less-than-ideal lubrication conditions.

Commitment to Quality and Innovation
The development and production of the HZ-20 series reflect the manufacturing expertise of Zhejiang Huazhou Technology Co., Ltd., a company with over a decade of experience in the field of self-lubricating bearings. From its facility in Nanxun, the company has built a reputation for combining technical capability with high production capacity, supported by modern equipment, an extensive mold inventory, and a skilled workforce.

Rather than relying solely on conventional bearing manufacturing approaches, the company continually explores new materials and application areas to meet evolving industry demands. This commitment has led to widespread adoption of its products in domestic markets across China and in international markets spanning more than a dozen countries, including Russia, Malaysia, and Romania.

Reliability Backed by Expertise
When selecting a bearing solution, the real measure of value lies in how well it balances performance, cost, and ease of upkeep. HZ-20 boundary lubricated bearings embody this balance through their POM-coated surface and oil storage technology, which together make them easier to maintain without compromising load-handling capacity. Combined with the design strengths seen in SF2 boundary-lubricated bearings, they offer a dependable choice for industries seeking to optimize equipment performance while controlling operational costs.

With a foundation built on engineering expertise, quality manufacturing, and customer-focused service, Zhejiang Huazhou Technology continues to set a high standard in the bearing industry—making solutions like the HZ-20 series not just a component, but a key contributor to long-term mechanical efficiency.
