Key features

Zero Backlash Connection: Creates a rigid connection with no backlash using mechanical interference fit and friction bond.

Easy Installation & Removal: Expands to fill gaps for easy assembly and disassembly using common tools, saving time.

Superior Holding Power: Clamping cones generate shaft torque superior to normal keyed hubs for high torque transmission.

Overload Protection: Slips when pre-set torque is exceeded, preventing damage to connected mechanical elements.

Precise Positioning: Allows accurate hub positioning on the shaft and facilitates angular timing without lock washers.

OEM/ODM Support: Manufacturer offers OEM and ODM services with ISO9001 certification for customized needs.

AI-Powered supplier vetting

SummaryThe supplier is identified as a Chinese manufacturer established in 2009, with 75 employees and a 3,000 m² manufacturing facility. Its stated products include flexible, grid, disc, gear, jaw, tyre, and other couplings, as well as shaft-transmission components; another description references screw pumps for oil and other high-viscosity fluids. Production evidence includes more than 10 production lines and stated coupling output of 3,000 tons. The supplier reports ISO9001:2008 and OHSAS18001:2007 certifications, four R&D engineers, and high-precision production and testing equipment. It exports to Russia, Europe, the United States, and Southeast Asia, although the export-sales proportion is stated as 11%–20%. Evidence is insufficient to assess after-sales service, financial credibility, customization capability, or specific customer cases.

Supplier typeThe supplier is explicitly described as a factory and manufacturer, legally organized as a limited company in China. This directly confirms that it operates as a manufacturing supplier rather than only a trading entity.

CertificationsThe supplier reports ISO9001:2008 and OHSAS18001:2007 certificates, along with other unspecified certifications. These stated management-system certifications provide explicit evidence supporting this field.

R&D capabilityThe supplier reports high-precision and advanced production and testing equipment and has four R&D engineers. These facts support technical development and process capability, but no information confirms patented products, proprietary technologies, or new-product development outcomes.

Production capacityThe supplier has 75 employees, a 3,000 m² manufacturing plant, more than 10 production lines, and stated coupling production of 3,000 tons. These explicit capacity indicators support an established production operation for coupling-related products.

Product Q&A

Q:How does the shaft locking device work?

It uses screw tension converted into radial pressure via an inclined plane to expand the device, eliminating gaps between the hub and shaft for a zero-backlash connection.

Q:Is the locking device easy to install?

Yes, it allows for easy installation and removal using common tools. A torque wrench is only needed for precise torque requirements.

Q:What happens during an overload?

The locking device will slip when the pre-set torque is exceeded, protecting connected elements from breaking. Note: It is not a friction coupling.

Q:Can the hub be positioned accurately?

Yes, the design allows the hub to be clamped at any position along the shaft, eliminating the need for lock washers, spacers, or stop rings.

Q:What materials and certifications are available?

The device is made of steel with polishing surface treatment. ISO9001 certification is available for customized orders.
