I. Application Areas

1. New Energy and Precision Manufacturing Equipment

Power battery production lines: In electrode sheet slitting equipment, extended flange bearings with a steel outer ring and copper inner ring can support long guide rails for high-precision linear motion. For example, Jiangsu Luyue's LMHC series bearings, through their extended design (such as the LMHC25LUU with a length of 112mm), reduce tool vibration amplitude to below 2μm, significantly improving electrode sheet cutting accuracy.

Semiconductor wafer transfer systems: The square extended flange adapts to the planar mounting requirements of the equipment frame. The self-lubricating properties of the inner copper alloy prevent lubrication grease from contaminating the clean environment, while the steel layer resists impact loads during wafer handling.

2. Industrial Automation and Heavy Machinery

Large gantry robots: The multi-bolt hole design of the extended flange (such as the LMK50L extended square type) provides a larger mounting contact surface, ensuring the stability of the robot arm during long-stroke movements and can withstand axial loads up to 1920N.

Mining conveying equipment: In the drive drum support of belt conveyors, the steel outer ring and copper inner ring structure resists dust erosion, and the extended flange is tightly connected to the frame with bolts, reducing loosening caused by vibration, and is suitable for extreme temperature environments from -40℃ to 300℃.

3. Construction Machinery and Vehicles

Agricultural machinery suspension systems: The square structure of the extended flange adapts to the right-angle mounting of the agricultural machinery frame. The inner copper alloy cushions soil impact, and the outer steel sleeve resists corrosion. For example, in the header lifting mechanism of combine harvesters, the bearing life is extended by 30% compared to traditional designs.

Special vehicle hydraulic rod guidance: Such as the telescopic guidance of fire truck ladders, the extended flange enhances torsional resistance through multi-bolt fixing, and the wear-resistant properties of the copper layer adapt to the high-friction conditions of frequent reciprocating motion of the hydraulic rod. II. Core Advantages

1. Installation Adaptability and Ease of Maintenance

Multi-scenario installation compatibility: The square flange can be directly connected to standard profiles such as channel steel and I-beams without additional adapters. For example, in automated production lines, the extended square design of LMK series bearings can quickly replace existing linear guides, improving installation efficiency by 40%.

Self-lubricating and maintenance-free: Graphite or molybdenum disulfide solid lubricants (oil content ≥12%) are embedded in the copper alloy, allowing operation even in environments where grease is prohibited, such as food machinery. The maintenance cycle is extended to more than 5 times that of traditional bearings.

2. Wear Resistance and Long Lifespan

Copper layer surface modification technology: For example, Jiangxi Hongda's steel-backed copper-based sintered bearings use micropores to absorb lubricating oil, which automatically overflows during high-speed movement to form a lubricating film. The friction coefficient is as low as 0.025, and the lifespan is increased by 20% compared to ordinary bearings.

Corrosion-resistant design: The outer steel sleeve is treated with electroplating or anodizing (such as the nickel plating process of the LMHC series), and the inner copper alloy is resistant to seawater corrosion, making it suitable for marine environments such as ship rudders.
