| Shock loads (Impulsive Torques) | Rubber limits transmitted torque by absorbing torque peaks and damping subsequent vibration. High overload capacity. | Low torsional stiffness very effectively limits high transmitted torque peaks of short duration. |
| Water Contamination | Immune | Immune |
| High Ambient Temperature | Limited to 60 Deg C. | Limited to 60 Deg C for natural rubber or 80 Deg C for neoprene. |
| Regular maintenance | None | None |

| Torsional Vibration | High amplitudes can be tolerated and controlled by inherent damping. Hysteresis heating imposes definable maximum vibration amplitude. | Low torsional stiffness and high damping properties provide a powerful method of control. Hysterisis heating imposes definable maximum vibration amplitude. A range of block hardness is available. |
| Life | Unlimited when used within design ratings. | Unlimited when used within design ratings. |
| Spares | Replacement link assemblies can be fitted without disturbing shafting balance. | Replacement blocks can be fitted in sets. |

| Reversing Loads | No problem since there is no backlash and the compressive pre-load in the rubber prevents stress reversal within design limits. | No problem since there is no backlash and the compressive pre-load in the rubber prevents stress reversal within design limits. |
| Cost of ownership | In most cases this is little more than the cost of the original installation. | In most cases this is little more than the cost of the original installation. |
| Acoustic Environmental Pollution | Rubber couplings provide very effective transmitted noise attenuation (which is why, for example, they are used in minesweepers). | Rubber couplings provide very effective transmitted noise attenuation (which is why, for example, they are used in minesweepers). |

| Design Flexibility | The modular linkage design, using rubber bushings having a wide variety of properties, lends itself to custom-designed solutions to almost any transmission need. | A range of block hardnesses and sizes and a variety of constructions can meet most demands within its power range. |
| Wear Due to Shaft Misalignment | The rubber bushings are pre-compressed and bonded in their housings so that there is no sliding contact and wear. | The blocks are compressed into their housings to eliminate wear when they are used within their design rating. |
| Mineral Oil Contamination | The low exposed rubber surface area allows this coupling to operate in air borne oil mist, but it is not suitable for total immersion. | Neoprene blocks are used for heavily oil polluted environments. |
