Product Description

Our custom stainless steel three-spoke handwheels are designed for food-processing machinery, sanitary equipment, process valves, machine tools, and industrial control systems.

Each handwheel features a rigid outer rim, an open three-spoke design, and a precision-machined central hub with a keyed bore. This structure provides a practical balance of mechanical strength, reduced weight, and smooth manual operation. The integrated keyway ensures secure engagement with the equipment shaft, helping prevent slippage and maintain consistent torque during use.

The typical manufacturing process includes investment casting, precision CNC machining, dimensional inspection, and application-specific surface finishing. Critical areas—including the shaft bore, keyway, hub faces, and outer rim—can be machined to customer-specified tolerances for accurate assembly, reliable alignment, and stable performance.

For sanitary and food-processing applications, smooth and easy-to-clean surface finishes are available. Material grade, overall dimensions, machining tolerances, surface roughness, and finishing requirements can all be customized according to customer drawings, 3D models, samples, or prototypes.

Typical applications include food-processing machinery, sanitary filter housings, process valves, pharmaceutical production equipment, industrial mixers, food-cutting equipment, and custom processing systems.

Frequently Asked Questions

What materials and surface finishes are available?

Standard material options include AISI 304, 316, and 316L stainless steel. Other stainless steel grades and special alloys can also be evaluated according to the operating environment, corrosion-resistance requirements, and mechanical performance of the application.

Available finishes include CNC machining, satin finishing, bead blasting, mechanical polishing, mirror polishing, electropolishing, and passivation. The most suitable finish can be selected according to the required appearance, corrosion resistance, cleanability, and surface roughness.

Do you offer custom sizes and dimensions?

Yes. The outer diameter, rim thickness, hub dimensions, center bore, keyway, spoke structure, machining tolerances, and surface finish can all be customized according to customer drawings, 3D models, samples, or prototypes.

Before production, our engineering team can review the design and provide recommendations regarding casting feasibility, machining allowances, tolerance control, and surface treatment.

What is the lead time for custom production?

Lead time depends on the selected material, component dimensions, order quantity, tooling requirements, machining complexity, and surface finish.

A new custom project normally includes drawing review, tooling development, sample casting, CNC machining, dimensional inspection, and sample approval before batch production. Repeat orders generally require less time because the tooling and manufacturing process have already been confirmed.

Please provide your drawing, required quantity, material grade, tolerance requirements, and surface finish specifications so that we can prepare an accurate production schedule.
