When it comes to designing products that demand reliable, controlled rotational motion—from household appliances to industrial equipment—choosing the right damper is make-or-break for user experience and long-term performance. The PR-T115G Rotary Damper stands out as a engineered solution, built to meet strict technical standards for torque, durability, and environmental resilience. Let’s dive into what makes this damper a top choice for projects requiring precision motion control.
Core Specs: Torque, Force, and Controlled Motion
At the heart of the PR-T115G’s performance is its ability to balance power and smoothness—critical for applications where both "easy operation" and "reliable control" matter.
Torque Range & Closing Time
The PR-T115G operates within a 1–8 N·m torque range, for medium-duty applications (think lid mechanisms, adjustable panels, or storage compartments). Under this specified torque, the damper delivers a nominal closing time of 11±4 seconds on standard test setups—with the flexibility to adjust this timing to match your product’s unique needs .
Even in low-angle scenarios, it maintains control: when the test machine begins free deceleration at a small 15° opening angle, the PR-T115G ensures a closing time of at least 0.5 seconds—preventing sudden, jarring motion that could damage components or risk user safety .
Lid Opening Force & Lift Assistance
User-friendliness is a priority: the PR-T115G requires less than 15N of force to open lids or panels, making it easy to operate for all users . For heavier loads, it goes a step further: the damper can provide up to 50% of its torque as lift assistant force (exact values calculated based on your selected specifications), reducing the effort needed to raise or adjust parts .
Rigorous Durability: Built to Last Through Thousands of Cycles
The PR-T115G isn’t just precise—it’s tough. It undergoes two key durability tests to ensure it performs consistently, even in high-use environments:
1. Free Fall Durability (30,000 Cycles)
This test simulates real-world wear: the damper is opened from 0° to 110° in 2 seconds, closed to 70°, then allowed to free descend to 0°—repeated 30,000 times. Afterward, it’s left to stand at room temperature for 24 hours. Even after this intense cycle, the PR-T115G still maintains a closing time of ≥3 seconds—no loss of performance 🔶10-15.
2. Forced Durability (10,000 Cycles)
For applications with faster motion demands, the PR-T115G is tested with reciprocal motion from 110° to 0° (each cycle completed in under 4 seconds). After 10,000 cycles and a 24-hour room-temperature rest, it still meets the ≥3-second closing time standard—proving its resilience in high-frequency use cases 🔶10-17.
Environmental Resilience: Perform Across Temperatures
Products often face diverse environments, and the PR-T115G is engineered to adapt:
- Recommended Operating Temperature: 0°C to 60°C—ideal for indoor, climate-controlled settings like kitchens, offices, or manufacturing floors .
- Maximum Storage Temperature: -20°C to 80°C (-4℉ to 176℉)—safe for shipping, warehousing, or short-term exposure to extreme conditions without compromising performance .
Quality & Compliance: Materials You Can Trust
The PR-T115G prioritizes both durability and environmental responsibility, with every component selected for performance and compliance with global standards (RoHS):
| Component | Material | Key Features |
|---|---|---|
| Back Cover | PA66-GF40 | Reinforced plastic; color-coded for different torque levels |
| Pin (Ph) | SUS304 | Corrosion-resistant stainless steel; natural finish |
| Compression Spring | SWP-B | Zinc-plated; passes 24-hour salt fog test for rust resistance |
| Linear Damper | SUS316 + POM | High-corrosion-resistance stainless steel + durable plastic |
| Camshaft & Bottom Case | POM | Strong, wear-resistant plastic; natural finish |
| Grease | PG08HB | Off-white, RoHS-compliant lubricant for smooth motion |

Visually, the damper is designed for function (not just appearance)—it should be free of damage and oil stains to ensure uncompromised performance 🔶10-22.
Who Should Use the PR-T115G?
This damper shines in applications where:
- Smooth, controlled closing/opening motion is non-negotiable (e.g., appliance lids, storage compartments).
- Durability through thousands of cycles is required (e.g., high-use industrial panels, consumer goods).
- Compliance with RoHS standards and temperature resilience are musts (e.g., global market products).
Final Thought: Precision That Delivers Peace of Mind
The PR-T115G Rotary Dampers isn’t just a component—it’s a guarantee of consistent, reliable motion control. From its carefully calibrated torque range to its rigorous durability testing and compliant materials, every detail is engineered to make your product safer, smoother, and longer-lasting.
Whether you’re designing a household appliance, industrial equipment, or a specialty device, the PR-T115G is built to meet the demands of precision motion control.
