As a professional manufacturer from Henan San Kuang Machinery Technology Co., Ltd. (established in 2014, with a factory area of 10,000-30,000 sqm and 51-100 skilled workers), we present our high-performance Reducer Coupling Helical Gearbox Input crafted from premium 42CrMo alloy steel. Designed to transmit a rated torque of 1000 Nm and accommodate shaft diameters from 25 to 45 mm, this coupling ensures reliable power transmission and long service life in demanding industrial applications. Whether you need to connect a motor to a helical gearbox or a reducer, our coupling offers excellent alignment compensation and vibration damping.
Our factory has exported products to over 20 countries across North America, South America, Europe, Southeast Asia, Africa, and Oceania, with an annual export value of US$2.5 million to US$5 million. We adhere to strict quality control systems certified under ISO9001, ISO14000, OHSAS18001 and many other international standards (e.g., ISO10441, TS16969, SA8000). All couplings are machined with precision and undergo 100% dimensional and hardness inspection before shipment.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
Q: Can this coupling be used for a helical gearbox input of different shaft sizes?
A: Yes, our coupling is designed to fit shaft diameters from 25 mm to 45 mm. If your shaft size is outside this range, we can offer custom machining (available upon request). -
Q: Is the coupling supplied with a keyway and setscrew?
A: Standard configuration includes a keyway (DIN 6885) and setscrew. If you need a clamping-type or taper bushing, please specify when ordering. -
Q: What is the maximum operating speed for this coupling?
A: The maximum speed depends on the balance grade. Standard G6.3 balancing allows up to 3000 rpm. For higher speeds, we can provide G2.5 balancing or lower. -
Q: Does your company provide samples before bulk order?
A: Yes, we offer samples for testing. Sample cost can be deducted from the bulk order quantity. Lead time for samples is typically 7-15 days. -
Q: What certifications do your products hold?
A: Our factory is certified under ISO9001, ISO14000, OHSAS18001, and also complies with TS16969, SA8000, QS9000, and others. Specific certificates can be provided upon request. -
Q: Can you customize the coupling dimensions or material?
A: Absolutely. We have full machining capability to modify bore size, keyway dimensions, or even change material (e.g., 20CrMnTi, 40Cr). Just send us your drawing or requirements. -
Q: How is the coupling packaged for export?
A: Each coupling is individually wrapped with oil-proof paper, then packed in plywood cases or pallets, suitable for sea freight. We also offer customer-specific packaging. -
Q: What is the typical lead time for a standard order of 100 pieces?
