QSN10-1 RG10 Tin Bronze Bushings And Bearings 10-1

QSN10-1 RG10 (i.e., 10-1 copper material) has a tin content of 9.0%-11.5% in its matrix, combined with trace amounts of lead (≤0.25%), giving QSN10-1 RG10 Tin Bronze Bushings and Bearings 10-1 unique "self-lubricating" and "impact-resistant" dual properties. Unlike ordinary aluminum bronze, this material has excellent anti-galling properties, making it particularly suitable for sliding mating parts such as lead screws, nuts, and worm gears. Even under high-frequency start-stop conditions, it will not sinter due to heat generation.

Customized Processes

As a professional enterprise integrating casting and machining, we have absolute control over our processes.

We possess 25 electric furnaces and 50 casting machines, supporting various processes such as sand casting and centrifugal casting. This means that whether you urgently need a single ultra-large copper gasket with a diameter of 2 meters or hundreds of thousands of 15mm precision miniature bearings, we can flexibly produce them without sacrificing tolerance accuracy.

We deeply understand that tolerance is the lifeline of our customers. Relying on two machining workshops and 30 advanced machines, we guarantee a machining allowance of 0.5mm on each side. For demanding customers, through solution treatment and aging heat treatment (which can increase hardness to HRC 40), we can control dimensional stability at the micron level.

Technical Parameters and Quality Assurance System

To avoid misleading information, we clarify and commit to the following measured data (based on spectrometer testing):

Physical Properties: Tensile strength ≥310 MPa; Brinell hardness HB 88-120 (far exceeding industry basic standards).

Coefficient of Friction: As low as 0.015 under lubrication conditions.

Application Limits

Maximum permissible sliding speed 8 m/s, maximum load-bearing pressure 20 MPa.

P-value (velocity-pressure product): Ideal for high-speed, heavy-duty bearings.

Trust Establishment: We have an independent testing laboratory. Every batch of QSN10-1 RG10 Tin Bronze Bushings and Bearings 10-1 must undergo spectroscopic material analysis and ultrasonic testing before leaving the factory. If the material does not meet the standards, we promise unconditional return and replacement—this is the confidence of a physical enterprise with a 40,000-ton production capacity certification.

Industry Application Panorama

Our products aren't just sitting in warehouses; they're actually in use in various core equipment:

Automotive Industry: Heavy-duty truck connecting rod bushings, turbocharger bearings (utilizing their high hardness and wear resistance).

Construction Machinery: Excavator bearing shells, crane pulley block copper bushings (utilizing their high load capacity of ≤20 MPa).

Precision Instruments: High-dimensional stability mold guide components (utilizing their low casting shrinkage).

Customer Testimonial: "We used to purchase bushings from a German brand, with a delivery time of 12 weeks. Fengquan not only reduced the price by 40%, but also delivered ISO-compliant replacement parts within 3 weeks through their rapid response customization capabilities. They've been running stably for two years without any problems." — Purchasing Director of a port machinery company in East China.
