The LOVEJOY L series jaw coupling is a flexible shaft connector that transmits torque between two rotating shafts while compensating for misalignment and reducing vibration. It is commonly used in pumps, gearboxes, compressors, and other industrial machinery where a maintenance-friendly coupling is required. MR supplies this line to customers across the US, Canada, Mexico, and South America and can help you select the right model.

The L series uses a size code: the letter L followed by a number such as L035, L150, L190, L225, or L276. This number does not indicate a direct measurement but groups together specific hub and spider combinations. Each size accommodates a range of shaft diameters and torque capacities, so the full part number often includes the hub bore and spider type. When requesting a quote, send the part number from your equipment or provide the shaft dimensions.

These couplings are found in a wide range of industrial applications: food and beverage plants, chemical and petrochemical facilities, water treatment, mining, and general manufacturing. Typical installations include centrifugal pumps, screw compressors, gearboxes, agitators, conveyors, and fans. The flexible jaw design handles angular and radial misalignment and dampens small vibrations, which helps extend the life of bearings and seals. They are also easy to assemble and disassemble without moving the connected machines.

To select the correct coupling, consider the equipment's nominal and maximum torque, rotational speed, shaft diameters, and load type. The standard spider is made of polyurethane, but different hardness options are available depending on the required rigidity and damping. During installation, align the shafts as accurately as possible; even though the coupling tolerates some misalignment, poor alignment accelerates wear on the spider and hubs. Check axial and radial play, and lubricate only if the manufacturer specifies it for the chosen spider.

LOVEJOY L series jaw couplings can be interchanged with similar couplings from other brands that follow the same design, such as KTR, Ruland, or Boston Gear. Compatibility depends on the size, hub bore, and spider type. If you have a part number from another brand or an unidentified piece, MR can identify a compatible alternative or quote the exact LOVEJOY part you need.

For a quote, send the coupling part number (for example, L035, L150, L190, L225, or L276) along with shaft diameters and spider type if known via WhatsApp or email. A photo of the part or equipment can also help identify the series. MR will respond promptly with the best option for your application.
