When power transmission demands absolute precision and zero slippage in demanding industrial applications, a standard motor shaft often falls short. This is where specialized components like the Dual Keyway Motor Drive Shaft become essential. Designed for enhanced torque transfer and secure component mounting, a Motor Shaft with Twin Key Slots provides two distinct, parallel keyways milled along its length. This dual-slot configuration allows for the simultaneous connection of two components, such as a gear and a pulley, or offers a backup keyway for simplified maintenance and repositioning. The robust design of our Double Groove Motor Transmission Shaft ensures reliable performance under high-stress conditions, preventing rotational play and misalignment. For electric motor applications requiring superior connectivity, our Twin Keyway Electric Motor Shaft offers the perfect solution, engineered to meet exact specifications for a seamless and durable power linkage.
The Dual Slot Keyed Motor Shaft is engineered with meticulous attention to detail to meet the rigorous demands of modern machinery. Manufactured from high-grade alloy steel, it undergoes precise machining, heat treatment, and finishing processes to achieve exceptional strength, wear resistance, and dimensional accuracy. Each shaft is crafted to ensure the key slots are perfectly parallel, with precise tolerances for a perfect fit with standard key stock. This guarantees maximum surface contact with the mating hub, distributing shear forces evenly and significantly enhancing the assembly's load-bearing capacity and service life. The availability of the second keyway provides critical flexibility in system design and assembly, allowing engineers to configure drives and transmissions more efficiently or create redundant connection points for safety-critical systems.
| Shaft Diameter (mm/in) | Standard Keyway Size (Width x Depth) | Typical Torque Capacity Range* | Common Applications |
|---|---|---|---|
| 20 mm / 0.787" | 6 mm x 3.5 mm / 0.250" x 0.125" | Moderate to High | Pumps, Fans, Conveyors |
| 35 mm / 1.378" | 10 mm x 5 mm / 0.375" x 0.188" | High | Industrial Gearboxes, Mixers |
| 50 mm / 1.969" | 14 mm x 5.5 mm / 0.500" x 0.250" | Very High | Heavy Machinery, Crushers |
| 70 mm / 2.756" | 20 mm x 7.5 mm / 0.750" x 0.375" | Extreme | Large Presses, Marine Drives |
*Torque capacity is indicative and depends on material grade, keyway fit, and application dynamics. Engineering consultation is recommended for specific requirements.
