Upgrade your grid coupling.
Get a lubrication-free and easy replacement coupling that allows visual inspection, has higher misalignment tolerance and vibration damping capacity without gradual imbalance.
Even if your grid coupling is not breaking, it might be damaging your system.
Grease points
add failure modes and human errors
Tight alignment
pushes stress into bearings and seals
Hidden wear
becomes leaks, hot bearings, and rework
What you gain upgrading to AT Coupling Monobloc
No lubrication
Less downtime, more reliability.
High misalignment tolerance
Works with real-life conditions and not only perfect set-ups.
Greater vibration damping
Protects shafts, gears, seals, and bearings.
Change without moving.
The AT Monobloc coupling is designed so the elastomer can be replaced without moving the assembly.
Without gradual imbalance
The monobloc structure keeps the coupling balanced during operation.
Visual inspection
Check conditions quickly, even during operation with a stroboscope light.
Multiple applications
Replace a grid coupling with great advantages in most applications.
Yes, the more aligned the better.
But you don't need the drama.
Parallel misalignment tolerances
Yes, we know that the most the alignment, the better. However, with the AT line you spare the drama.
With misalignment tolerances up to 974% (parallel ) and 1640% (angular) greater than grid couplings, it’s much simpler to achieve (and maintain) the required shaft alignment without damaging the system.

Failure point elimination
strengthens your FMEA plan.
Frequently Asked Questions
Having 100% metallic structure, the grid coupling generates greater reactionary forces than the AT Monobloc Coupling. This means gear coupling transmits more vibrations and shocks to the system. Also, the greater spring coefficient, it stiffness increases with speed.
No. These models are better than grid couplings, but have lower torque capacity. Also, the AT Monobloc coupling does not generate gradual imbalancing, a chronic problem of traditional tire couplings.
After installation, the AT Monobloc coupling doesn’t require moving the equipment to change the coupling. It is a simple operation like changing a tire.
For extreme application, such as environments with acids, solvents or bases, we developed the ANTAC line, with a special formulations that will resiste these harsh environment conditions.
Yes. US-based local stock and quick response through phone (786) 866-2899.
