Product Description
Engineered for exceptional performance in demanding environments, our LT/TL Series Flange Coupler is a high-power, flexible coupling solution. This robust flange coupler is constructed from high-grade steel, making it an ideal choice for applications requiring the durability and corrosion resistance akin to a stainless steel coupling. Its gear-type structure with an elastic pin (pin-bush) design delivers outstanding torque transmission—rated up to 20,000 N.m—while effectively accommodating shaft misalignments, damping vibrations, and absorbing shock loads. This protects critical connected equipment like motors, pumps, and gearboxes from premature wear.
The coupling operates efficiently at high speeds up to 8500 r/min and is available in a comprehensive size range (TL1 to TL13) with customizable bore diameters. Its standard design ensures easy integration and maintenance, while options for OEM and ODM support provide the flexibility to meet your specific machinery requirements. Whether for heavy machinery, industrial fans, or complex processing systems, this flange coupler offers reliability and long service life, backed by a significant warranty.
Features
Robust Flange Design: Provides a secure and rigid connection for high-torque applications.
High-Strength Material: Manufactured from durable steel, suitable for demanding environments.
Elastic Pin/Bush System: Allows for flexibility to handle misalignment and dampen vibrations.
High Torque & Speed Capacity: Rated for up to 20,000 N.m torque and 8500 r/min speed.
Wide Model Range: Available in standard models from TL1 to TL13 to suit various power requirements.
Customizable: OEM/ODM support available for bore sizes (e.g., up to 300mm) and colors.
Long Warranty: Backed by a comprehensive warranty for assured reliability.
Description
The LT/TL Series is a flange-type flexible coupling designed to transmit power in middle to high-power machinery. It consists of two flanged hubs connected by a set of pins and elastic bushings (often nylon or rubber). This “pin and bush” configuration is the key to its flexibility, allowing it to compensate for minor shaft misalignments while transmitting high levels of torque. The flange connection makes it particularly suited for applications where a disconnection point is needed without moving the connected machinery. It is a versatile and reliable solution for industries ranging from mining and steel production to marine and power generation, ensuring smooth and continuous operation.
