Hansheng Automation (Dongguan) Co., Ltd.

1. Product Introduction This precision spline shaft / Mop Roller Driver is the core drive component we have customized for high-end cleaning appliances, such as floor scrubbers and robotic vacuum cleaners. As a factory specializing in the manufacturing of precision mechanical components, we employ "turn-milling" and "power skiving" processes to produce various high-precision involute spline shafts, rectangular spline shafts, and irregular drive shafts, which are widely used in household appliances, automation equipment, and the automotive industry.

2. Why choose our shaft?

(1). Extreme silent performance (concentricity control): Pain points: Common bearings experience large runout due to multiple clamping, resulting in loud noise during high-speed operation.
Our solution: We utilize a turning and milling center to complete the machining of the outer circumference, end face, and keyway in a single setup, ensuring that the coaxiality between the bearing position and the tooth section is ≤ 0.01mm. This guarantees that the motor operates without vibration and produces low noise during high-speed rotation.

(2). Complex tooth profile machining capability: Equipment: Utilizing Japanese Kashifuji gear shaving machines / Ningjiang gear hobbing machines.
Capability: Whether it's involute splines, rectangular splines, or special anti-slip knurling, we can achieve precise molding with an accuracy level of ISO 5-6.

(3). Excellent surface treatment: The journal area is precision-ground, achieving a roughness level of Ra 0.2 - 0.4 (mirror-finish quality).
The surface of stainless steel can undergo passivation treatment to enhance its rust-proof ability, making it perfectly suitable for humid working environments.
