Zero Backlash Connection: Creates a friction bond eliminating gaps between hub and shaft for precise torque transmission.
Superior Holding Power: Clamping cones generate shaft torque superior to normal keyed hubs for enhanced security.
Overload Protection: Device slips when pre-set torque is exceeded to prevent damage to connected elements.
Easy Installation and Removal: Saves time over traditional interference fits with common tools and no need for lock washers.
Multi-Feature Resistance: Flame-retardant, anti-static, oil-resistant, cold-resistant, corrosion-resistant, and heat-resistant.
Precise Positioning: Allows hub to be positioned accurately on shaft and facilitates angular timing adjustments.
Versatile Application: Suitable for textile, garment, conveyor, packaging, food, marine, mining, and agricultural machinery.
Customizable Certification: Available with ISO9001 certification upon request to meet specific quality standards.

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 locking device connect the hub to the shaft?
A:
It uses a keyless mechanical interference fit that converts screw tension into radial pressure to eliminate gaps.
Q:What happens if the torque exceeds the pre-set limit?
A:
The locking device will slip to prevent the connected elements from being broken, acting as an overload protector.
Q:Do I need special tools for installation?
A:
No, common tools are sufficient for locking and unlocking, though a torque wrench is recommended for precise torque.
Q:Can the hub be positioned at any point on the shaft?
A:
Yes, the design allows the hub to be clamped at any position along the shaft without needing spacers or stop rings.
Q:What materials and features does the device have?
A:
Made of steel with polishing surface treatment, it is flame-retardant, anti-static, oil-resistant, and corrosion-resistant.
