Product Introduction

The SF bearing is a self - lubricating sliding bearing that adopts a three -layer composite structure as its core design. Through meticulous material selection and structural optimization, it excels in oil - free lubrication, high wear resistance, and adaptability to complex working environments. These features make it an ideal solution for scenarios where traditional lubrication methods are difficult to implement or where high maintenance costs are a concern. SF bearings are widely used in various industrial fields, such as metallurgy, mining, machinery, and automotive industries. They are particularly suitable for scenarios where traditional lubrication is difficult to achieve (such as oil free or difficult to oil environments) or where maintenance costs are high. SF bearings, with their self-lubricating, high wear-resistant, and adaptable features, have become a new type of bearing that can replace roller bearings, oil containing bearings, and copper alloy bearings, and are widely used in various industrial fields.

Features

1.SF bearings do not require external lubrication and are suitable for scenarios where refueling is not possible or maintenance is difficult.

2.The friction coefficient of SF bearings is low, with a dry friction of approximately 0.04~0.20, reducing energy loss and heat generation.

3. SF bearings have high wear and corrosion resistance PTFE layer is resistant to chemical corrosion and bronze powder layer enhances wear resistance.

4.SF bearings have good running in performance protecting the surface of the grinding shaft and avoiding shaft biting.

5. SF bearings have low noise and seismic resistance, which can reduce mechanical vibration and operating noise

6.SF bearings have high adaptability and a wide temperature range, with a working temperature range of -195 ℃~+240 ℃.

Application

SF bearings are commonly used in printing machines, Food Machinery, textile machines, micro motors, automotive suspension systems, agricultural machinery etc.
