In the precision world of mechanical equipment, Bronze wrapped Bearings have become an indispensable core component of modern industry with the excellent performance of high load bearing, long life and low maintenance. The combination of its innovative design and material science has not only subverted the application mode of traditional cast bronze bushings, but also demonstrated a strong market potential under the trend of energy saving, emission reduction and lightweight manufacturing.
Core Advantage: Technical innovation drives efficient production
1. Material innovation, performance breakthrough Bronze wrapped Bearings use high-density copper alloys (e.g. CuSn8, CuSn6.5P, etc.) as the substrate, and through the precision rolling process to form an oil storage structure (diamond or hemispherical oil pockets), which greatly improves lubrication efficiency. The material combines high hardness (90-120 HB) with excellent wear resistance and a static load capacity of up to 470 N/mm² and a dynamic load of up to 40 N/mm², which makes it particularly suitable for rough friction surfaces.
Lightweight and cost-effective Compared to conventional cast bronze bushings, the coiling process saves more than 30% of bronze material and improves machining efficiency by 50%. The thin-walled design reduces the weight of the bearing by 20%-30%, which is suitable for compact machinery and significantly reduces the overall cost of the equipment.
Long-lasting lubrication and low maintenance Surface oil storage structure can extend the lubrication cycle to 5 times of the traditional bronze bushings, some models (such as FB090) combined with solid lubricants (graphite, PTFE) to achieve self-lubrication, suitable for high temperature (-100 ℃ ~ +260 ℃) or can not be frequent refueling extreme working conditions.
Application Scenario:Multi-fields to empower industrial upgrading
· Heavy-duty and low-speed fields: lifting machinery, mining equipment, metallurgical rolling mills, etc., with high load-bearing capacity (PV value up to 2.8N/mm²-m/s) to ensure stable operation of equipment.
· Automotive and transportation: used in chassis drive shafts, gearboxes and engine components to reduce friction loss and improve fuel efficiency.
· Precision manufacturing: machine tool guideways, hydraulic systems, relying on its low coefficient of friction (0.08 ~ 0.25) to achieve high-precision motion control.
· Emerging fields: aerospace engines, robot joints and other high-end scenarios, to meet the needs of severe working conditions through lightweight and high temperature resistance.
