Precision Machined Crank Arm for Mechanical Assemblies

These high‑precision machined crank arms belong to custom‑made Sheet Metal Products, and are typical Semi‑finished products designed for mechanical rotating assemblies. Produced through cutting, stamping and precision machining processes, these crank arms are strictly controlled with 0.5 concentricity tolerance to guarantee smooth rotation performance. Every mounting hole is precisely positioned to ensure reliable interchangeability during downstream installation. Dimensional accuracy, flatness and hole concentricity are fully inspected for each production batch. These crank arms are widely used as core transmission parts for assembling mechanical structures, matching well with Steel Equipment Frames, and can be integrated into combined units together with Chassis & Cabinets and Equipment Sheet Metal Housings. Our factory supports custom shape, hole layout and machining tolerance according to client technical drawings. As durable OEM Components, these crank arms can receive s…
