Lovejoy NB-8 universal joint replacement with TSC300 Industrial 3/4″ shaft power transmission couplings replace universal joints in any industrial power transmission application
Couplings in an industrial power transmission setup have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology, industry has evolved but the technology that makes up the universal joint has not. Twin Spring Coupling offers something different.
Industrial power transmission is broken into two main areas, high speed low angle of misalignment and lower speed higher angle of misalignment. Traditionally these two needs have been service by two different couplings – Motion control couplings like beam, bellows, jaw, elastomeric type couplings and the universal joint.
The problem with both couplings are their fundamental design weaknesses, for motion control coupling they can run fast but cannot work at over 4 degrees of misalignment before they start to wear out. The Lovejoy NB-8 universal joint can run at more than 4 degrees but needs constant maintenance to keep the bearings and pivot point greased or they too will wear out quickly.
On top of that they traditionally cannot run over 8 degrees before technical issues like balancing and bearing wear become issues. In a 24/7/365 situation like industrial power transmission that’s going to create interruption and a increased annual maintenance bill.
TSC300 how it’s different to a Lovejoy NB-8
The one piece design means no greasing, no replacing components just a annual checkup, vital in industrial 24/7 applications
Twin Spring Coupling (TSC) 300 has no internal components so no annual maintenance and can run at high and low speed as needed.
Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM.
