Spline Shaft
The spline shaft offered by Metalwork Petroleum Technology Co, Ltd. is a precision‑machined power‑transmission component made from alloy steel 42CrMo (also known as 42CrMo4 or AISI 4140). It is supplied in diameters ranging from 20 mm to 300 mm and is fabricated to DIN, AGMA or GB/T standards. The shafts undergo heat treatment and precision grinding to achieve the strength required for high‑load applications.
The alloy steel provides a tensile strength of approximately 900 MPa after quenching and tempering, a typical value for 42CrMo shafts used in wind‑turbine main spindles and automotive gearboxes. Surface hardening is applied to a typical case depth of 0.5 mm, and the spline profile is produced with a typical tooth accuracy of 0.02 mm. These characteristics align with industry practice for components that must transmit torque with minimal backlash.
Typical buyers include OEMs of wind turbines, automotive transmission manufacturers and heavy‑equipment producers. The supplier can customise length, spline geometry and surface finish, and requests for specific dimensions should be confirmed directly. Trade terms, lead times and incoterms are not listed and should be negotiated with the supplier before placing an order.
| Material | Alloy Steel 42CrMo (42CrMo4 / AISI 4140) |
| Diameter range | 20 mm - 300 mm |
| Standard compliance | DIN, AGMA, GB/T (as specified by buyer) |
| Heat treatment | Quench and temper to achieve ~900 MPa tensile strength (typical for 42CrMo) |
| Surface hardness | Typical case hardening depth 0.5 mm, surface hardness up to 45 HRC |
| Spline tooth tolerance | Typical tooth profile tolerance ±0.02 mm |
| Packaging | Typical bulk packing in wooden crates with protective padding |
| Weight per metre | Typical weight 2.5 kg per metre for 30 mm diameter (varies with size) |
| Coating | Typical zinc‑phosphate corrosion‑resistant coating (optional) |
| Finish | Typical precision grinding finish Ra 0.8 µm |
Metalwork Petroleum Technology Co, Ltd. is located at District C, No. 1 Road, Liqiao Town, Shunyi District, Beijing, China, postal code 100010. The company is classified in the harbor trust tier and currently shows a response rate of 0 % on the platform. It specialises in steel smelting, forging, heat treatment and high‑precision machining for large‑size shafts and related components.
The factory operates over twenty‑seven annealing furnaces, twenty‑two heating furnaces and two bell‑type electric furnaces, enabling heat‑treatment of parts up to 20 t and 18.5 m in length. Its machining capability includes CNC lathes, gantry milling machines, horizontal lathes and deep‑hole drilling rigs, allowing production of ultra‑long and large‑diameter shafts such as those used in 0.75 MW - 3 MW wind‑turbine spindles. Export destinations reported include the Netherlands and Germany.
Spline shafts are precision-machined power transmission components with involute or straight-sided spline profiles for torque transfer in gearbox assemblies. Made from heat-treated alloy steel such as 42CrMo, these shafts are widely used in wind turbine main spindles and automotive transmission systems. Available in sizes from 20mm to 300mm diameter, conforming to DIN, AGMA, or GB/T standards with surface hardening and precision grinding for high-load applications.

Sourcing Spline Shaft from Metalwork Petroleum Technology Co, Ltd. - China Import Guide
Before placing an order, confirm the exact diameter, spline profile and any surface‑treatment requirements with Metalwork Petroleum Technology Co, Ltd. Request a technical data sheet that lists the heat‑treatment parameters, hardness values and dimensional tolerances for the specific batch you intend to purchase. Verification of the supplier’s certifications for heat‑treatment equipment and machining capability will reduce the risk of non‑conforming parts.
Logistics for these large shafts typically involve container or bulk freight depending on length and weight. Discuss preferred Incoterms, such as FOB Beijing or CIF Shanghai, and agree on payment terms before production begins. Lead times are not published, so obtain a realistic schedule from the supplier that accounts for machining, heat treatment and final inspection.
Quality assurance should include dimensional inspection using calibrated gauges, hardness testing according to ASTM E10 and surface‑finish measurement. Request third‑party inspection reports or arrange on‑site audit if the order volume warrants it. Ensure that mill test certificates and material test reports accompany the shipment to verify compliance with the agreed specifications.
