We specialize in producing bimetallic bearings, specifically offering the JF-800 bimetallic strip with a CuPb10Sn10 lining, as well as plain shaft bushings tailored for the tractor industry. Our bimetallic bearings, made from various alloys, are essential components in plain bearing surfaces, typically serving as self-lubricating materials. However, we can provide alternative alloys upon request. These materials are available in different forms, including ingots for centrifugal or static casting, or as welding rods for repair and joining applications. Notably, our tin-based alloys are environmentally friendly, being lead-free and boasting superior technical characteristics.
Our product range includes:
- Bimetallic Bearing Plain Shaft Bushings
- Centrifugal Casting Services
Centrifugal casting is renowned for its premium quality, especially suited for bearings that don’t require thick liners. For those with thicker liner needs, other methods like static casting may be more advantageous.
Static Casting Expertise: Our team is proficient in static casting, a method where alloys solidify from the bottom upwards, ensuring a strong bond from the inside out.
Welded Linings: Our welding expertise ensures top-quality linings, comparable to those achieved through centrifugal casting, with no restrictions on the alloy, whether tin- or lead-based.
We understand that wear and damage to rotors, crankshafts, and pistons can lead to significant operational losses. By offering expert repair and fabrication services, including the manufacturing of bushings and bearings, we aim to reduce your downtime and save you money.

Available in various forms like cylindrical bushes, flanged bushes, thrust washers, and sliding plates, JF800 bearings can be customized to meet specific needs.
When choosing a JF800 bimetallic bearing, it’s crucial to account for the application’s specific load, speed, temperature, and lubrication requirements. Consulting with experts in bimetallic bearings can guide selecting the most suitable material and design for optimal performance.
Bimetallic bearings, often referred to as bimetal bushes, are specialized composite bearings composed of two distinct metal layers fused together. The exterior layer is usually crafted from a bronze material known for its low-friction characteristics, while the interior layer is constructed from steel, providing enhanced strength and durability. These bearings are designed to outperform traditional single-metal bearings in applications that demand high load-bearing capacity and are subject to intense stress.
The structure of bimetal bushes Bushing typically features a steel base that delivers structural strength and stability, coupled with a lead bronze alloy surface that excels in reducing friction and wear. This dual-layer construction not only supports substantial loads and absorbs shocks effectively but also offers remarkable resistance to wear and corrosion. Bimetal bushes find widespread application in various sectors, including automotive engines, gearboxes, agricultural machinery, and other areas where heavy-duty performance is essential
Manufacturers provide an array of bimetal bushing compositions, including CuPb10Sn10, CuPb24Sn4, CuPb30, and AlSn20Cu, to cater to diverse operational needs.
