SF-TEX Corrosion-Resistant Self-Lubricating Stainless Steel Bushing Bearing With PTFE Fabric

Product Description:

Steel with PTFE fbre fabric.This new material uses the PTFE fibers fabric overlay on metal backings, the fabric has a very high load capacity and much longer operating life compared with conventional 3-layer bushes. the metal can be carbon steel(SF-TEX), stainless steel(SF-TEX3), bronze(SF-TEXB) etc. Suitable for rotary and oscillating movement, lower maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviors, and good resistance to shock loads. much longer service life under lower speed with high load.

Product Introduction

SF-TEX Corrosion-Resistant Self-Lubricating Stainless Steel Bushing Bearing with PTFE Fabric

The SF-TEX corrosion-resistant self-lubricating stainless steel bushing bearing is engineered for demanding industrial applications. Its PTFE fabric lining ensures low friction, maintenance-free operation, while the stainless steel body provides superior corrosion resistance, making it perfect for food processing, marine, and chemical environments.

  • Self-lubricating – PTFE-embedded fabric reduces friction, eliminating the need for external grease.
  • Corrosion-resistant – Made from high-grade stainless steel, ideal for wet & acidic conditions.
  • High load capacity – Supports heavy-duty machinery without wear deformation.
  • Low maintenance – No relubrication required, reducing downtime.
  • Wide temperature range – Performs reliably in high-temperature environments (up to 260°C / 500°F).

Applications

  • Food & Beverage Machinery (FDA-compliant, no contamination risk)
  • Chemical Processing Equipment (Resists acids, alkalis, and solvents)
  • Marine & Offshore Applications (Withstands saltwater corrosion)
  • Automotive & Heavy Machinery (Handles high loads with minimal wear)
  • Pharmaceutical & Medical Devices (Non-toxic, hygienic design)

Why Choose SF-TEX Bearings?

Unlike traditional bronze or plastic bushings, the SF-TEX self-lubricating stainless steel bushing bearing combines durability, low friction, and chemical resistance in one solution. Its PTFE fabric lining ensures smooth operation even in high-load, high-temperature environments, making it a cost-effective, long-lasting alternative to standard bearings.


Frequently Asked Questions

Q: Can SF-TEX bearings be used in underwater applications?

A: Yes! The marine-grade stainless steel and PTFE fabric make them ideal for saltwater and submerged environments.

Q: Do these bushings require lubrication?

A: No, the PTFE fabric lining provides self-lubrication, eliminating the need for grease.

Zhejiang Shuangnuo Bearing Technology Co., Ltd.
Zhejiang Shuangnuo Bearing Technology Co., Ltd. is China SF-TEX Corrosion-Resistant Self-Lubricating Stainless Steel Bushing Bearing With PTFE Fabric Suppliers and Wholesale SF-TEX Corrosion-Resistant Self-Lubricating Stainless Steel Bushing Bearing With PTFE Fabric 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.
