High-Performance Bimetal Bearings | Steel-Backed Bronze Bushings
Product Description
The Optimal Solution for High-Load, Lubricated Applications
When your design demands a bearing that can withstand high loads and significant stress while operating smoothly under lubrication, bimetal bushings offer an exceptional combination of strength, wear resistance, and value.
Yile Machinery manufactures a wide range of bimetal composite bearings, engineered with a steel backing and a sintered bronze alloy lining. This construction delivers the structural integrity of steel with the superior sliding properties of bronze, making it the ideal choice for a multitude of demanding mechanical and automotive applications.
Key Features & Benefits:
High Load & Fatigue Strength: The robust steel backing provides exceptional structural support, allowing the bearing to handle heavy loads, shock, and high-pressure conditions without deformation.
Excellent Wear Resistance & Low Friction: The inner surface is a sintered layer of a lead-tin bronze alloy (e.g., CuPb10Sn10). This material provides a superb, low-friction sliding surface that is highly resistant to wear and seizure when properly lubricated.
Customizable Lubrication Features: The bronze inner surface can be machined with custom oil grooves, holes, and indentations (pockets). This allows for optimized lubricant distribution, ensuring a stable hydrodynamic film is maintained, which dramatically extends the service life of the bearing and the shaft.
Cost-Effective Performance: The bimetal design provides the high-performance bearing characteristics of bronze precisely where they are needed, while the steel backing offers a strong, economical structure. This makes it a more cost-effective solution than solid cast bronze bushings.
Dimensional Stability: These bearings exhibit excellent thermal conductivity to dissipate heat and maintain stable operating clearances over a wide range of temperatures.
Proven Performance in Demanding Applications
Our bimetal bushings are trusted components in machinery where reliability and durability are critical. They are engineered to perform as direct replacements for OEM parts or as components in new designs.
Typical Applications Include:
Automotive: Engine connecting rods, rocker arms, camshafts, gearbox gears, clutches.
Industrial Machinery: Hydraulic pump and motor thrust plates, pivot pins for construction equipment.
Agricultural Equipment: Linkage points, gearboxes, and high-load pivots.
Whether you need a standard size or a custom-designed bushing with specific lubrication patterns, we have the manufacturing capability to meet your exact requirements.
