Flexible Jaw Coupling Manufacturer in Pune
SSPTP is a flexible jaw coupling manufacturer in Pune, producing jaw couplings at our Bhosari MIDC works for industrial customers who need a low-maintenance, shock-absorbing way to connect two rotating shafts. Every flexible jaw coupling we manufacture uses a three-part design two metal hubs and a replaceable elastomeric insert sized to the torque and shaft-diameter requirements of your application.
- Industry’s standard shaft coupling
- Accommodates for angular and parallel shaft misalignment
- Fail-safe (will still perform if elastomeric “spider” fails)
- No metal to metal contact
- Resistant to oil, dirt, sand, moisture, and grease
- Industry’s largest available selection from stock
As a flexible jaw coupling manufacturer and supplier in Pune, SSPTP designs and machines every jaw coupling at our own Bhosari MIDC facility. Jaw couplings are one of the most widely specified coupling types in general industrial use, valued for their simplicity, low cost, and tolerance for shaft misalignment — and as a Pune-based manufacturer, we size and supply them both as single replacement units and as ongoing production-line requirements.
Whether you’re looking for flexible jaw couplings in Pune for a single machine repair or sourcing from a flexible jaw coupling supplier in Pune for a larger installation, our team works directly with you on shaft size, torque rating and elastomeric insert hardness to specify the right coupling for the job.
What Is a Flexible Jaw Coupling?
What Is a Flexible Jaw Coupling?
A flexible jaw coupling connects two rotating shafts using two metal hubs one mounted on each shaft with a flexible elastomeric insert, often called a “spider,” fitted between them. Unlike a rigid coupling, the elastomeric insert allows the coupling to absorb shock loads and vibration while still transmitting torque efficiently between the two shafts.
How a Flexible Jaw Coupling Works
Torque is transmitted from the driving hub, through the elastomeric spider, to the driven hub. Because the spider is flexible rather than rigid, it compresses slightly under load, which absorbs shock and cushions the connected equipment from sudden torque spikes. The jaw design also means there’s no direct metal-to-metal contact between the two hubs during normal operation the elastomeric insert is the only point of contact which reduces wear and eliminates the need for lubrication.
Flexible Jaw Coupling Components
A flexible jaw coupling manufactured by SSPTP consists of three main parts:
- Driving hub: mounted on the motor or driver shaft
- Elastomeric insert (spider): the flexible element that sits between the two hubs and absorbs shock and misalignment
- Driven hub: mounted on the load or driven shaft
Key Features of Our Flexible Jaw Couplings
- Industry-standard shaft coupling design – A widely used, well-proven coupling type for general industrial shaft connections.
- Accommodates angular and parallel shaft misalignment – The flexible elastomeric insert allows for a degree of both angular and parallel misalignment between the connected shafts.
- Fail-safe operation – Even if the elastomeric spider fails completely, the jaws of the two hubs can still make contact and continue transmitting torque, rather than causing an immediate, total loss of drive.
- No metal-to-metal contact under normal operation – The elastomeric insert is the only contact point between hubs, reducing wear and eliminating the need for lubrication.
- Resistant to oil, dirt, sand, moisture and grease – Suited to real industrial environments rather than only clean, controlled conditions.
- Available in a range of sizes and insert hardness options – The coupling can be matched to both the torque requirement and the amount of shock absorption needed.
How to Select the Right Flexible Jaw Coupling
- Shaft diameter — the coupling’s bore must match (or be machinable to) both the driving and driven shaft diameters.
2. Torque requirement — calculated from your motor’s horsepower and operating RPM, this determines the minimum coupling size needed.
3. Expected misalignment and shock load — applications with higher vibration or shock loading may need a softer elastomeric insert; applications needing maximum torque transfer may use a harder insert.
Frequently Asked Questions
SSPTP is a flexible jaw coupling manufacturer in Pune, based at Bhosari MIDC, producing jaw couplings for general industrial shaft-connection applications.
Flexible jaw couplings are fail-safe by design, if the elastomeric spider fails, the jaws of the two hubs can still make contact and continue transmitting torque, rather than causing a sudden, complete loss of drive.
No, because there’s no metal-to-metal contact under normal operation, flexible jaw couplings don’t require lubrication, unlike some other coupling types.
Yes, as a flexible jaw coupling supplier in Pune, we supply both single replacement units and ongoing bulk requirements for production lines.
Provide your shaft diameter, motor horsepower and operating RPM, and our team will recommend the correct coupling size and insert hardness. See the selection guide above for the full method.
