As a direct supplier from China source factory, relying on more than ten years of precision shaft processing experience and national high-tech enterprise technical strength, Guanshuo supplies high-quality Multi Keyway Motor Shaft products for global customers. We implement whole-process quality control from raw material incoming to finished product delivery, equipped with more than 60 sets of advanced CNC processing equipment and complete sets of precision testing instruments. Our products pass CE, ISO9001 and other international certifications, widely serving customers in heavy machinery, industrial automation, new energy and other fields, recognized by global customers with stable quality and professional services.
Many equipment engineers and purchasing managers have encountered these headache problems: single key often shears and breaks under heavy load causing downtime, keyways wear fast requiring frequent replacement, centering is difficult during assembly requiring repeated debugging, large vibration and noise during operation, and it is hard to find suppliers for non-standard special keyways. Our multi-keyway motor shaft is born to solve these industry pain points, comprehensively optimized from structural design to production process, completely solving various chronic problems of traditional key connections.
1. Solve key breakage problem: Multiple keys bear load together, avoiding single key stress concentration, shear strength increased by more than 2 times, completely solving the problem of key breakage and downtime under heavy load impact.
2. Solve wear problem: Precisely ground key side fitting, larger contact area, smaller specific pressure, keyway wear life increased by more than 3 times, reducing maintenance and replacement frequency.
3. Solve centering problem: Natural positioning by multiple keys, higher coaxiality, no need for repeated dial indicator alignment during assembly, assembly efficiency increased by 50%, also avoiding vibration caused by eccentricity.
4. Solve adaptation problem: Support customization of any keyway quantity, angle, depth, whether standard or non-standard special specifications can be delivered quickly, solving the problem of difficult sourcing for special equipment.
Under high power, large torque, frequent forward and reverse working conditions, the advantages of Multi Keyway Motor Shaft multi-key structure are particularly obvious, helping customers greatly reduce equipment failure rate, reduce downtime losses, and improve overall production efficiency.
We adopt advanced CNC milling, form grinding processes to process keyways, strictly control the angle accuracy, indexing accuracy and symmetry of keyways. The side of keyways is precision ground, surface roughness reaches Ra1.6~3.2μm, fitting clearance controlled in the optimal range, lower noise and smoother operation during transmission. Products are made of high-quality 45# steel, 40Cr alloy steel and other raw materials, through quenching and tempering, quenching and other professional heat treatment processes, key part hardness is uniform, core toughness is sufficient, balancing wear resistance and impact resistance.
● Precision milling processing: Adopt imported machining center to complete all keyway milling in one clamping, ensure keyway angle error controlled within ±15′~±30′, indexing accuracy far exceeds industry standards.
● Keyway grinding treatment: Keyway sides are precision ground by special grinding machine to remove processing tool marks and burrs, good key side parallelism, tighter fit with keys, reduce transmission impact and abnormal noise.
● Professional heat treatment: Provide different heat treatment solutions such as quenching and tempering, high frequency quenching, carburizing according to customer working conditions, hardness uniformly controlled in HRC28-55 range, avoiding early failure caused by local over-hard or over-soft.
● Flexible customization ability: Can customize keyway quantity, angle, spacing, size according to customer needs, perfectly adapt to special installation space and complex transmission requirements, small batch non-standard orders can also be delivered quickly.
Both ends of Multi Keyway Motor Shaft are chamfered with C0.5~C2, good guidance during assembly, will not scratch the inner wall of mounting hole, workers install more conveniently, also avoid stress cracking caused by sharp corners.
We organize production strictly in accordance with international standards and customer drawing requirements, all key dimensions are inspected by precision equipment such as three-coordinate, two-coordinate measuring instrument, ensuring product interchangeability and transmission reliability. The following are the core precision parameters of the product, all indicators meet or exceed industry general standards:
| Parameter Item | Accuracy Index |
|---|---|
| Symmetry of keyway to axis | ≤0.02~0.03 mm |
| Equal division angle error | ≤±15′~±30′ |
| Chamfer at both ends | C0.5 ~ C2 |
| Keyway side surface roughness | Ra 1.6~3.2 μm |
In addition to the above standard parameters, we also can customize other precision indicators according to customer special requirements, from material selection to heat treatment process, from dimensional tolerance to surface treatment, all can be personalized customized. Each batch of products is accompanied by complete material certificate, hardness report and dimensional inspection report, support third-party inspection agency inspection, let customers purchase without worry.
We know that packaging and logistics of industrial parts directly affect customers' production schedules, so we have established a standardized packaging and delivery process, from product rust prevention to logistics tracking, to ensure products are delivered to customers intact and on time.
● Rust-proof packaging: Each product is first treated with anti-rust oil, then sealed with independent PE anti-rust bag to avoid rust during transportation, suitable for long-term shipping and storage.
● Sturdy outer packaging: Inner boxes are packed in hard cartons with separators, outer layers are packed with export-free fumigation wooden pallets, suitable for international long-distance transportation, will not be damaged by extrusion and collision.
● Flexible logistics: Support express (DHL/FedEx/UPS), air freight, sea freight, also can arrange customer designated freight forwarder to pick up goods, meeting different delivery time requirements.
● Delivery guarantee: Standard specification products have safety stock, can be shipped within 3-5 days after order; custom products delivered in 15-30 days, urgent orders can open green channel for priority production.
● Progress tracking: After order confirmation, special sales will follow up production progress, update production status every 48 hours, provide logistics tracking number after shipment for full tracking.
Whether it is small batch samples or large quantity orders, we treat them with the same standard, ensuring that every Multi Keyway Motor Shaft is delivered to customers intact and on time, without delaying customers' production plans.
