When it comes to precision machinery and equipment, hardened steel bushings play a crucial role in ensuring smooth and reliable operation. Among the various materials available, GCr15 and 45# steel are two of the most commonly used for hardened steel bushings, especially in metric sizes.

GCr15 steel, also known as bearing steel, is a high-carbon chromium bearing steel that offers excellent wear resistance, hardness, and toughness. It is widely used in the manufacturing of bearings, bushings, and other precision components due to its superior mechanical properties. When hardened and precision ground, GCr15 steel bushings provide a long-lasting and dependable solution for applications requiring high-speed rotation or heavy loads.

On the other hand, 45# steel is a medium-carbon steel that offers good strength and machinability. It is often used in the manufacturing of various mechanical parts, including bushings. While it may not have the same wear resistance as GCr15 steel, 45# steel bushings are still a cost-effective choice for many applications where the load and speed requirements are not as stringent.

When selecting hardened steel bushings in metric sizes, it is important to consider the specific requirements of your application. Factors such as load capacity, rotational speed, and operating environment will all affect the choice of material and design. Additionally, precision ground bushings offer tighter tolerances and better surface finishes, ensuring optimal performance and longevity.

Wh you are replacing worn-out bushings or designing a new system, GCr15 and 45# steel hardened steel bushings in metric sizes are reliable options that can meet your needs. With their superior mechanical properties and precision manufacturing, these bushings will provide smooth and reliable operation for your machinery and equipment.

Solid Bushing Hardened Steel Bushing Material S45C

Hardened steel bushings made of high quality low carbon steel or stainless steel with special technology. The surface can be cemented to improve hardness.

Hardened steel bushings are available in cylindrical, flanged and special configurations that are designed for a variety of applications, including earth moving equipment such as excavators and loaders; Drilling equipment; agricultural machines including harrows, plows and backhoes; Construction machines including grabs, buckets and grabs; and hydraulic cylinders, where they protect against wear from floors and eyes. Other applications include industrial washing machines, slide guides for industrial presses and components for suction pumps, machine tools and automatic machines.

With the advantages of low weight, low noise level and self-lubricating properties, VIIPLUS bearings are often used in the automotive industry.

Currently, over 50 sockets are used in every car. More and more traditional sintered bearings with needle bearings are being replaced by self-lubricating bearings. In addition to the bushings, the self-lubricating materials are applied to the other non-load-bearing parts such as the new resin-coated swash plate for the air conditioning and other components already developed by VIIPLUS.
