Product Structure

1. T-Shaped Hexagonal Body – Six-lobe (hexagonal) design with T-shaped cross-section for secure engagement with coupling jaws.

2. Polyurethane Material – Premium PU elastomer provides excellent wear resistance, oil resistance, water resistance, and elasticity.

3. 95 Shore A Hardness – High hardness ensures stable mechanical performance, good wear resistance, and long service life.

4. Precision-Molded Dimensions – Consistent quality and dimensional accuracy for reliable fit.

💡 How it works: The T Series hexagonal cushion fits between the two hubs of a T-type coupling or water pump coupling. The six-lobe (hexagonal) design engages with the jaws of the coupling hubs, transmitting torque while absorbing shock, dampening vibration, and compensating for misalignment. The T-shaped cross-section provides secure axial retention. The polyurethane material flexes elastically to absorb shock loads, extend equipment life, and reduce maintenance costs.

FAQ

Q: What is a T Series hexagonal cushion?
A: A T Series hexagonal cushion (also called a T-shaped coupling buffer pad or water pump coupling cushion) is a polyurethane elastomer insert with a T-shaped hexagonal (six-lobe) design. It fits between the two hubs of a T-type coupling to transmit torque, absorb shock, and dampen vibration in pump and motor drive systems.

Q: What material is used?
A: The cushion is manufactured from premium polyurethane (PU) – offering excellent wear resistance, oil resistance, water resistance, high fatigue strength, and impact resistance.

Q: What is the hardness?
A: The standard hardness is 95 Shore A ± 2A – providing high wear resistance and stable mechanical performance.

Q: What sizes are available?
A: Available sizes range from T45/40 to T154 – covering most standard T-type coupling and water pump applications.

Q: What is the temperature range?
A: The standard operating temperature range is -40°C to +100°C.

Q: Does the cushion require lubrication?
A: No. The T Series cushion is maintenance-free – no lubrication required.

Q: Is the cushion oil and water resistant?
