uxcell 5pcs L75 Jaw Coupling Insert Red Urethane Flexible Solid Center

Description

Product Overview

The uxcell L75 jaw coupling insert set is engineered to meet the demanding requirements of modern industrial power transmission applications. Each package contains five precision‑machined urethane center inserts, finished in a vibrant red color for easy visual identification during installation and maintenance. The inserts feature an inner diameter of 19.6 mm (0.77 in) and an outer diameter of 44 mm (1.73 in), providing a perfect fit for standard L‑type jaw couplings. Constructed from high‑grade urethane, the inserts combine the flexibility needed to absorb shock and vibration with the rigidity required for accurate torque transfer, ensuring smooth operation across a wide range of speeds and loads.

Designed as a solid‑type center piece, the insert eliminates the common issues associated with split‑type designs, such as misalignment and uneven wear. The solid construction enhances torsional rigidity, reducing the risk of backlash and improving overall system efficiency. In addition, the urethane material offers excellent resistance to oil, chemicals, and temperature variations, making it suitable for harsh industrial environments. The red coloration not only aids in quick part identification but also serves as an indicator of wear, allowing maintenance personnel to replace inserts before performance degradation occurs.

Usage

This coupling insert is ideal for a broad spectrum of rotating equipment, including but not limited to gearboxes, motor drives, conveyor systems, pumps, and compressors. Its universal design ensures compatibility with most L‑type jaw couplings used in the manufacturing, material handling, and processing sectors. Whether you are retrofitting an existing system or building a new line, the insert provides a reliable connection that minimizes vibration transmission to adjacent components, thereby extending bearing life and reducing maintenance costs.

Installation is straightforward: align the splines of the insert with the corresponding slots on the coupling halves, press the insert firmly into place, and verify that the jaws are fully engaged. The process requires no special tools, and the solid design prevents the insert from rotating independently, guaranteeing consistent alignment during operation. Once installed, the coupling can handle shock loads and transient torque spikes without compromising the integrity of the drive train.

Because the insert is made from urethane, it performs well in environments where temperature ranges from -30 °C to +80 °C, and it resists degradation from common industrial fluids such as hydraulic oil, coolant, and lubricants. This makes the product a dependable choice for applications in food processing, chemical manufacturing, automotive assembly, and other sectors where exposure to aggressive media is routine.

FAQ

What size L‑type jaw couplings are compatible with this insert?

The insert is sized for L‑type jaw couplings with an inner diameter of 19.6 mm (0.77 in) and an outer diameter of 44 mm (1.73 in), which corresponds to the standard L75 series used in most industrial applications.

Can the urethane insert be used with high‑speed motor drives?

Yes. The urethane formulation is engineered to maintain its flexibility and damping characteristics at speeds up to 3,600 rpm, making it suitable for high‑speed motor drives when paired with the appropriate coupling hardware.

How often should the inserts be inspected or replaced?

Inspection frequency depends on operating conditions, but a visual check during routine maintenance is recommended every 6 months. The red color provides a clear indication of wear; if the insert shows significant discoloration, cracking, or deformation, it should be replaced promptly to maintain optimal performance.

Is this product suitable for food‑grade applications?

The urethane material complies with many food‑grade standards, but for strict sanitary requirements, users should verify that the specific formulation meets the relevant FDA or equivalent certifications for their region.

What warranty does uxcell offer on this coupling insert?

uxcell provides a one‑year limited warranty covering material defects and workmanship. Should any issue arise within the warranty period, contact our support team for a replacement or repair solution.
