ASTM 4140 Shaft Sleeve
Spacer Bush is mainly used in mechanical equipment to isolate and support parts, preventing direct contact and friction between adjacent parts, thereby reducing wear and interference. It is widely used in transmission gear, bearing seat, gear box and other parts, can significantly reduce friction and wear, extend the service life of equipment and improve work efficiency

Description
Product Description
Spacer Bush/Shaft Sleeve/Bushing/Pin, though structurally simple, play a core role in mechanical systems by providing protection, support, and connection.
When selecting these materials, consider the specific application requirements: choose metal for high loads, plastic or stainless steel for corrosive environments,
and elastic rubber or self-lubricating composite materials for vibration scenarios. With the advancement of industrial automation and new energy technologies,
lightweight, self-lubricating, and long-lasting materials (such as polyurethane and nanocomposites) will become mainstream, driving mechanical components
towards higher efficiency and lower maintenance.
Applications:
Spacer Bush/Shaft Sleeve/Bushing/Pin are commonly used in industrial machinery, automotive transportation, aerospace,
new energy and environmental protection equipment, etc.,
playing a key role in mechanical connection, transmission support, wear protection and joint rotation scenarios.
Production Specifications
Materials: 20#, 45#, bearing steel, 42CrMo steel, stainless steel
Tolerance of Dimensions: ±0.01mm (1 silk = 0.01mm)
Hardness: 63 (the unit of hardness is not specified here, usually it could be HRC, such as 63HRC for Rockwell hardness)
Surface chrome plating and other treatments are also available.
Our advantages:
With the rapid development of the global infrastructure construction industry, there is a strong demand for construction machinery parts.
To make the most of our factory's advantages in the steel pipe industry, our factory established a new production workshop for
shaft sleeves in 2015. The production process covers lathe processing, heat treatment, carburizing, grinding, and finished product packaging.
This not only enables excellent quality control but also reduces the product cost, presenting obvious advantages.
Currently, our products are in short supply due to high demand.
