Product Overview

The Lovejoy L‑series jaw coupling is a widely‑used fail‑safe flexible shaft jaw‑type coupling for motor power transmission. It consists of two metal jaw hubs and an L‑type elastomer spider insert. The spider insert works as a buffer component to absorb shock, damp vibration and compensate minor angular & parallel shaft misalignment. We supply complete L‑series jaw couplings as well as replacement spider inserts in stock, OEM custom‑molded service is supported according to drawings or samples. For enquiries, please confirm coupling size number and quantity for accurate quotation.

Key Features & Benefits

• Fail‑safe design: equipment still runs even if elastomer spider insert is damagedLovejoy
• Outstanding shock‑absorbing and vibration‑damping performance, protects motor and driven machinery
• Easy assembly & disassembly, no lubrication required, low‑maintenance cost
• Dimensionally interchangeable with standard Lovejoy L‑series, direct drop‑in replacement

FAQ

Q1: What is fail‑safe feature for Lovejoy L‑jaw coupling? 

A: Even the elastomer spider insert breaks, metal jaws will interlock and keep transmitting torque to avoid sudden equipment shutdown.

Q2: Can you supply only replacement spider insert (without metal hubs)? 

A: Yes, both complete coupling sets and separate replacement L‑spider inserts are available.

Q3: What information should I offer for quotation? 

A: Please provide L‑size number and purchase quantity; specify material if special requirement.
