Stainless Steel Bushing
Profab’s stainless steel bushings are CNC machined with high precision and standardized heat treatment to provide excellent wear and corrosion resistance for a wide range of machinery and equipment.
Stainless Steel Bushing Manufacturer in China
The core function of stainless steel bushings is to reduce friction between two moving parts and prevent wear. They are primarily used to provide the necessary support and guide movement in mechanical systems. A minimum of 10.5% chromium content in stainless steel creates a self-repairing oxide layer on the surface. This provides the bushing with unrivaled protection. The self-lubricating properties and multi-layer compound construction also make stainless steel bushings suitable for use in harsh environments.
Profab Machine is a professional stainless steel bushing processing factory. We offer various types of stainless steel bushings, such as Flange Bushings, Ball Bushings, Grooved Bushings, Composite Bushings, 304 Stainless Hex Bushings, 316 Stainless Hex Bushings, and so on.
- Excellent corrosion resistance
- High hardness and low coefficient of friction
- Dimensional accuracy ±0.01 mm
- Easy to install and maintain
Variety of Applications For SS Bushing
Medical
Due to their excellent corrosion resistance and biocompatibility, bushings are a trusted component in surgical instruments and medical devices. In these areas, precision, reliability, and the absence of lubrication are essential.
Marine
Stainless steel bushings (especially 316 stainless steel) have excellent resistance to corrosive saltwater effects. They are therefore ideal for corrosion-resistant sliding positions, marine fittings, valves and pump trims. They also ensure long life for fittings in harsh marine environments.
Automotive
These bushings are widely used in the suspension systems of cars and trucks. They are used to reduce friction and wear between components, contributing to vehicle performance and durability .
Chemical
Stainless steel bushings are able to withstand a wide range of acids and alkalis without degradation. Typically used in hydraulic valves for acid and alkali flow measurement. Ensures reliable performance in highly corrosive chemical processing environments.
Industrial
Usage scenarios range from pumps, motors, and conveyor systems to metallurgical continuous casting machines, steel rolling equipment, mining machinery, steam turbines, and injection molding machines. Stainless steel bushings ensure reliable operation under heavy loads and varying temperatures.
Aerospace
In critical applications such as aircraft engines and landing gear, stainless steel bushings provide the necessary support and friction reduction to meet the stringent requirements of the aerospace industry.
