Product Introduction

SF-1S Self-Lubricating Stainless Steel Bushing Bearing - Maintenance Free, High Temperature Use

The SF-1S Self-Lubricating Stainless Steel Bushing Bearing is engineered for high-performance applications where reliability and durability are critical. Designed to operate maintenance-free, this bearing eliminates the need for external lubrication, reducing downtime and operational costs. Its stainless steel construction ensures superior corrosion resistance, while the self-lubricating design allows smooth operation even in high-temperature environments up to 280°C.


Perfect for food processing machinery, chemical equipment, marine applications, and high-load industrial systems, the SF-1S delivers long-lasting performance with minimal wear.

  • Maintenance-Free Operation – No need for grease or oil, reducing upkeep costs and downtime.
  • High-Temperature Resistance – Performs reliably in extreme heat, ideal for furnaces, ovens, and industrial dryers.
  • Corrosion-Resistant Stainless Steel – Withstands harsh environments, including marine and chemical exposure.
  • Low Friction & High Load Capacity – Engineered for smooth motion under heavy loads, enhancing equipment lifespan.
  • Self-Lubricating Design – Embedded solid lubricants ensure consistent performance without external lubrication.
  • Material: Stainless Steel (Grade [304/316/420 etc.])
  • Applications: Food processing, chemical handling, marine, automotive, packaging machinery

Common Applications

  • Food & Beverage Machinery – FDA-compliant, ideal for conveyor systems and mixers.
  • Chemical Processing Equipment – Resistant to acids, alkalis, and solvents.
  • Marine & Offshore Systems – Performs in saltwater environments without rusting.
  • High-Temperature Industrial Ovens – Maintains stability under continuous heat exposure.
  • Automotive & Heavy Machinery – Reduces wear in high-load pivot points.

Why Choose Our SF-1S Bearing?

Unlike traditional bearings that require frequent lubrication, the SF-1S self-lubricating bushing bearing ensures long-term reliability with zero maintenance. Its stainless steel construction makes it ideal for corrosive and high-temperature environments, while the embedded lubricants provide consistent performance even under heavy loads.

Zhejiang Shuangnuo Bearing Technology Co., Ltd.
Zhejiang Shuangnuo Bearing Technology Co., Ltd. is China SF-1S Stainless Steel Bearing Suppliers and Wholesale SF-1S Stainless Steel Bearing Company, we are a manufacturer specializing in producing various self-lubricating copper alloy products using centrifugal casting, continuous casting, metal mold casting, and other processes. Its main products include brass, aluminum bronze, tin bronze, and others produced according to national standard grades. It processes and produces various solid inlaid self-lubricating bearing products on this basis . At the same time, it uses sintering technology to produce bimetallic products and many other types of products. Since its establishment nearly 10 years ago, the company has focused on the research development, and production of various new self-lubricating bearings.

In the process of product production, our company has always insisted on independent casting production of raw materials to ensure the quality of products from the source; during the casting process, the whole process is monitored, and the finished product is tested by spectrometer three times before, in and after the furnace to confirm the material composition of the product. The national testing agency is regularly commissioned to test the material composition and mechanical properties of the product, and authoritative test reports can be provided to customers in need; the company implements integrated production from material to finished product processing and has more than 80 sets of advanced CNC machine tools, CNC lathes, machining centers, and other major equipment. The strong production capacity ensures that the material production is organized for customers for the first time, shortening the production cycle.
