Product Description
In mechanical systems, a splined connection provides robust torque transmission. However, when a steel shaft mates with a steel hub, friction and wear can quickly lead to component failure. The solution is a bronze spline bushing.
As a sacrificial wear component, a custom-machined bronze bushing protects the more expensive and critical steel shaft. Yile Machinery is a precision manufacturer of bronze and brass wear parts, including splined bushings, hubs, and sleeves, made to your exact specifications.
Bronze alloys are the ideal choice for sliding and high-wear applications due to their unique properties. They are softer than hardened steel shafts, ensuring that the easily replaceable bushing wears out, not the shaft itself. We work with a variety of high-performance copper alloys:
Aluminum Bronze (e.g., C95400, C95500):
High Strength & Hardness: Offers exceptional wear and abrasion resistance, making it ideal for high-load, low-speed applications.
Excellent Corrosion Resistance: Performs well in marine and chemical environments.
Phosphor Bronze / Tin Bronze (e.g., C93200 / SAE 660):
Superior Lubricity: Contains properties that reduce the coefficient of friction, perfect for applications requiring smooth sliding motion.
Good Fatigue Resistance: Withstands repeated stress cycles without failure.
Brass Alloys:
A cost-effective option for lower-load applications where good corrosion resistance is still required.
The effectiveness of a spline bushing depends entirely on its fit. A loose fit will cause backlash and impact loading, while a fit that's too tight will prevent sliding and cause binding.
Our manufacturing process guarantees a perfect fit every time:
CNC Turning & Milling: We machine the bushing's outer diameter, inner diameter, and overall shape to extremely tight tolerances.
Precision Spline Cutting: Using specialized broaching or shaping processes, we cut the internal splines (involute, straight-sided, or serrated) to perfectly match the profile of your shaft.
Quality Control: Every finished part is dimensionally inspected to ensure it conforms precisely to your technical drawing.
Our custom bronze bushings and hubs are essential in:
Industrial Gearboxes: For sliding gear selectors and connecting hydraulic motors.
Construction & Agricultural Machinery: In PTO (Power Take-Off) shafts and transmission systems.
Presses & Stamping Equipment: As guide bushings and clutch hubs.
Marine Propulsion: For propeller shaft connections and steering systems.
Any application requiring a strong, replaceable wear surface on a splined shaft.
Our expertise in machining bronze extends to a wide range of custom wear components:
Wear Plates & Guide Liners
Thrust Washers
Plain Sleeve Bearings
