“I need the hydraulic damper function, but I don’t need self-closing. I can’t find this solution in the market. Can Waterson help?” Donovan Teo, Hardware Distributor.
Traditional hydraulic hinges generally include both self-closing and damper control, which can be beneficial for users who want self-closing and no slamming doors at the same time. However, these two functions can’t be separated in traditional door-closing systems.
Recently, Mr. Teo contacted Waterson to locate a hydraulic door hinge that wouldn’t slam while in use . He hoped to avoid slamming that was not only hazardous to guests, but sounded terrible and tended to damage the door frames and other high-end components related to the entryways.
Anti Slam Hydraulic Door Hinge Design
To solve Teo’s problem, a heavy-duty soft close hydraulic hinge is an ideal option because of its oil buffer control and mechanical braking system. This hinge can be easily adjusted to slow a door and avoid violent slamming as needed. Each soft closing hinge is an innovative design with dual function that is located on opposite ends of the barrel. For example, the HA type provides a hydraulic damper (H) to close the door and a swing speed (A) to reduce the closing speed. Waterson offers six distinct types — DS, SA, SA1, HS, SB & HA (noted on the inside leaf). These can be configured to meet your particular needs.

Hydraulic Hinges Weight Capacity vs Traditional Hinges
Weight capacity should be the next consideration when you apply an anti-slam door hinge. Most customers when they reached Waterson, they all mentioned that “my old hinges just dropped out and a whole door collapsed”. Therefore, here are some weight feature comparisons between heavy duty hydraulic hinges and traditional hinges.
| Feature | Hydraulic Hinges | Traditional Hinges |
|---|---|---|
| Load-Bearing Capacity | High – Designed for heavy doors, load distribution | Moderate to Low – Suitable for standard doors |
| Support for Door Weight | Handles up to 260-440 lbs (varies by model) | Typically supports up to 100-150 lbs |
| Wear & Durability | Enhanced – Reduced strain due to hydraulic damping | Higher wear over time with increased strain |
| Best Applications | Heavy-duty industrial, commercial, residential doors (e.g., metal, wooden, glass, etc.) | lightweight doors |
| Maintenance Needs | Low – Hydraulic system reduces impact on the hinge | Moderate – More frequent adjustments over time |
Heavy-duty hydraulic hinges are truly a game-changer if you need a special load-bearing for your door. Not only will the hinge save your budget, it also saves your time in maintenance and energy to install and adjust. Read hydraulic door closer vs spring hinge comparison here.
