Product Description
L Type Elastic Coupling – Replace Lovejoy L070-L150, NBR Spider, 1000 RPM, Oil Resistant
Factory direct | Powder metallurgy hubs | NBR rubber spider | Oil, dirt, sand, moisture & grease resistant | 1000 RPM | Fail-safe design | No lubrication required | Lovejoy L070-L150 compatible | OEM/ODM/OBM
The Apexcoupling L Type Elastic Coupling is a cost-effective, high-performance jaw coupling designed as a direct replacement for Lovejoy L-series couplings (L070 to L150) . Featuring a three-piece design – two powder metallurgy hubs and one NBR (Nitrile Butadiene Rubber) spider – this coupling delivers reliable torque transmission, vibration damping, and misalignment compensation at an economical price point. The NBR rubber spider provides excellent resistance to oil, dirt, sand, moisture, and grease, making it ideal for harsh industrial environments. With easy disassembly, lightweight construction, and no lubrication required, the L Type coupling is the perfect solution for wave soldering machines, pumps, compressors, conveyors, fans, and general industrial machinery.
✅ Economical and practical – simple construction, lightweight, easy to disassemble, and maintenance-free. Commonly used in wave soldering machines and general industrial drives.

Product Structure
Two Powder Metallurgy Hubs – Sintered iron construction (L035-L150) – precision-machined, economical, and durable.
One NBR Rubber Spider – Solid center design – Nitrile Butadiene Rubber (Buna-N) with excellent oil resistance and resilience.
Set Screw Fastening – Secure shaft connection – quick and easy installation.
💡 How it works: The L Type coupling consists of two standard L Type hubs and one elastomeric spider. The spider sits between the jaws of the two hubs, transmitting torque while absorbing shock, dampening vibration, and compensating for angular and parallel misalignment.
