3/4″ to 1″ L090 3-Piece L-Jaw Coupling Set & Buna-N NBR Rubber Spider for Log Wood Splitter

Description

Product Overview

The AUTOJARE L090 L‑Jaw Coupling Set is engineered for demanding power transmission applications where reliability and durability are paramount. This three‑piece kit includes two precision‑machined alloy steel coupling halves and a high‑performance NBR rubber spider that together accommodate both 3/4″ and 1″ bore sizes. Constructed from HT250 alloy steel, each half offers exceptional tensile strength, resistance to wear, and a long service life even under heavy cyclic loads. The NBR rubber spider provides flexible torsional damping, reducing shock loads and protecting downstream equipment from sudden torque spikes. All components are finished in a sleek black coating that resists corrosion and enhances visual identification during installation. The set is compact, measuring just 2.72 x 2.44 x 2.40 inches, and weighs only 1.43 pounds, making it easy to handle and store. With a part number LZQ‑019 and UPC 713153729956, this coupling set meets industry standards for flexible multi‑flex couplings and is listed as a top‑ranked product in its category.

Usage

This coupling set is ideally suited for log wood splitters, small to medium‑size industrial machinery, and any application that requires a secure yet flexible connection between shafts. The 3/4″ bore version features a 3/16″ keyway, while the 1″ bore version includes a 1/4″ keyway, each with a set screw for quick and secure mounting. Installers can easily align the coupling halves with the shaft, insert the NBR spider, and tighten the set screws to achieve a firm, vibration‑damped connection. The design is interchangeable with popular brands such as Lovejoy, Martin, Browning, and TB Woods, allowing seamless integration into existing equipment without the need for additional adapters. Whether used in a workshop, on a construction site, or in a manufacturing line, the L090 set delivers consistent performance, minimizing downtime and maintenance costs. Its robust construction also makes it suitable for outdoor environments where exposure to moisture and temperature fluctuations is common.
