7/16 to 7/8 Flexible L-Jaw Coupling Set L075 Saelno Multi-Flex

Description

Product Overview

The Saelno L075 Flexible L‑Jaw Coupling Set is engineered to deliver dependable power transmission across a wide range of industrial and agricultural machinery. Designed for shafts with bore sizes from 7/16″ to 7/8″, the set includes two cast‑iron HT250 coupling halves, each featuring a precision‑machined keyway—3/32″×3/64″ for the 7/16″ side and 3/16″×3/32″ for the 7/8″ side. The halves are joined by a high‑grade NBR rubber spider that absorbs shock and dampens vibration, extending the life of both the coupling and the connected equipment. A blackened surface treatment provides excellent corrosion resistance, ensuring the coupling remains rust‑proof even in harsh, moisture‑laden environments. The package also contains four set screws and a dedicated wrench, allowing for quick, tool‑free installation and adjustment. With a compact package dimension of 2.56 × 2.05 × 1.93 inches and a weight of just over one pound, the L075 set offers a balance of strength and portability that is rare among comparable multi‑flex couplings.

Usage

Designed for versatility, the L075 coupling excels in a variety of applications. In wood‑splitting equipment, the flexible joint accommodates slight misalignments between the motor and the splitting bar, reducing stress on the drivetrain and delivering smoother operation. Air compressors and pneumatic pumps benefit from the rubber spider’s ability to isolate vibrations, which helps maintain consistent pressure output and reduces noise levels. The coupling is also suitable for conveyor belts, blowers, and agricultural machinery such as grain augers and feed mixers, where reliable torque transfer is essential. Its interchangeable design makes it compatible with popular brands like Lovejoy and Martin, allowing users to replace worn couplings without the need for extensive re‑engineering. Whether installed in a workshop, a farm, or an industrial plant, the L075 provides a dependable link that can handle fluctuating loads and occasional shock loads without compromising performance.

FAQ

What shaft sizes are compatible with the L075 coupling?

The L075 is designed for shafts with bore diameters of 7/16″ (with a 3/32″×3/64″ keyway) and 7/8″ (with a 3/16″×3/32″ keyway). It can be used on any equipment that matches these dimensions.

Can the coupling be used with other brands such as Lovejoy or Martin?

Yes. The L075’s dimensions and keyway specifications are interchangeable with many popular brands, making it a suitable replacement for Lovejoy, Martin, and similar couplings.

Is the rubber spider replaceable if it wears out?

The rubber spider is a standard NBR component that can be ordered separately. Saelno provides part numbers for easy re‑ordering, ensuring the coupling can be maintained over its service life.

What is the torque capacity of this coupling?

While the exact torque rating depends on the specific application and operating conditions, the HT250 cast‑iron construction typically supports torque levels suitable for most wood splitters, compressors, and medium‑size industrial drives.

How do I install the set‑screw kit correctly?

Begin by aligning the two coupling halves on the shafts, ensuring the keyways match the shaft keys. Insert the rubber spider, then place the set screws through the designated holes and tighten them evenly using the supplied wrench. Verify that the coupling rotates freely without excess play before full operation.
