Lovejoy L-190 1 3/4″ Buna-N Jaw coupling alternative – The TSC300 1 3/4″.
TSC300 1 3/4″ jaw coupling replacement for industrial jaw coupling users. Replace your L-190 with a maintenance free, flexible shaft coupling alternative.
Couplings in the industrial sector traditionally are broken into two sectors, jaw couplings that can only run at angles of 1° or less, as they cannot physically flex beyond that. The other are universal joints.
L-190 Jaw couplings are 3 piece elastomeric couplings, an input and output hub and a spider insert, the insert can be made up of 3 different materials SOX – (NBR / Buna-N / Nitrile rubber insert), Urethane, Hytrel and Bronze.
Each insert gets progressively stiffer and less able to absorb vibration so the angular misalignment becomes smaller with each insert. This coupling is broken down across two Twin Spring Coupling models.
The Sox/Buna-N and Urethane models with the TSC300 and the Hytrel and Bronze with the TSC500 model.
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 standard jaw coupling.
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 Lovejoy L-190 jaw 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 1° degrees of misalignment before they start to wear out.
The 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. Either way bearings need to be replaced due to wear.
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 couplings that’s going to create interruption and a increased annual maintenance bill.
TSC300 how it’s different to the Lovejoy L-190 SOX.
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. Now available in Metric.
Flexible Up to 45 degrees.
Constructed from 4140 Alloy.
