Lovejoy L-190 1 1/4″ Hytrel/Bronze Jaw coupling alternative, the TSC500.
TSC500 1 1/4″ T6061 T6 Aluminum jaw coupling replacement, replace your L-190 jaw coupling with a maintenance free alternative.
Couplings in the industrial sector traditionally are broken into two sectors, jaw couplings that can only run at angles of 1° or less otherwise they wear out, as they cannot physically flex beyond that. The other are universal joints.
Lovejoy L-190 Jaw couplings are a 3 piece elastomeric coupling, an input and output hub and a spider insert, the insert made of Hytrel and Bronze means it can only flex to 1/2°.
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 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 couplings 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° of misalignment before they start to wear out. With Hytrel or Bronze its only 1/2° so even less.
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.
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.
TSC500 how it’s different to the Lovejoy L-190.
The one piece design means no greasing, no replacing components just a annual checkup, vital in industrial 24/7 applications.
Twin Spring Coupling (TSC) 500 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 25 degrees.
Constructed of High strength, corrosion resistant T6061 Aluminum.
