Description
Product Overview
The Uxcell L090 jaw coupling insert set is engineered to meet the demanding requirements of modern industrial power transmission systems. Each package contains two identical red urethane center inserts that serve as the heart of L‑jaw coupling assemblies. With an inner diameter of 20 mm (0.8 in) and an outer diameter of 53 mm (2.1 in), these inserts provide a precise fit for standard shaft sizes while delivering the flexibility needed to absorb misalignment and reduce vibration. The urethane material is selected for its combination of elasticity and durability, offering a solid‑type design that resists wear, maintains torsional rigidity, and extends the service life of both the coupling and the connected equipment. The vibrant red color not only aids in quick visual identification during installation and maintenance but also signals the high‑performance nature of the component. Designed for seamless integration, the inserts feature splined interfaces that align perfectly with the L‑jaw coupling housing, ensuring a secure, slip‑free connection that can handle a wide range of torque loads.

Usage
These urethane inserts are ideally suited for a variety of rotating machinery across multiple industries. In conveyor systems, they help mitigate the effects of shaft misalignment caused by long belt runs, reducing wear on bearings and extending overall equipment uptime. Pump installations benefit from the vibration‑damping properties of the urethane, which protect sensitive seals and maintain consistent flow rates. Machine drives that operate at high speeds or under variable loads find the solid‑type design advantageous for maintaining precise torque transmission while minimizing backlash. The inserts also perform well in applications such as mixers, crushers, and gearboxes where shock loads are common. Installation is straightforward: align the splines on the insert with those on the coupling housing, press the insert into place, and verify proper engagement. No additional tools or fasteners are required, making the process quick and reliable for maintenance personnel.

FAQ
What shaft sizes are compatible with the L090 insert?
The L090 insert is designed for a 20 mm (0.8 in) inner diameter, making it compatible with shafts that match this size. It is commonly used in applications where the shaft diameter falls within the 0.75‑0.85 in range, providing a snug fit without excessive play.
Can the insert be used in high‑speed applications?
Yes. The urethane material maintains its elasticity and strength at speeds up to 3,600 rpm, making it suitable for many high‑speed drives. However, for extremely high‑speed or high‑temperature environments, users should verify the specific operating limits with the manufacturer.
How does the red color affect performance?
The red pigment does not impact the mechanical properties of the urethane. Its primary benefit is visual, allowing technicians to quickly confirm that the correct part is installed and to spot any wear or damage during routine inspections.
Is additional lubrication required?
No additional lubrication is needed for the urethane insert itself. The material’s inherent low‑friction characteristics reduce the need for greases or oils, simplifying maintenance and preventing contamination of surrounding components.
What warranty does Uxcell provide?
Uxcell offers a one‑year limited warranty covering material defects and manufacturing errors. Customers can contact Uxcell technical support for assistance with any issues that arise within the warranty period.
