PR-T115G: A Patented Damper Solution for Heavy-Lid Washing Machines

Peir’s patented PR-T115G rotary damper addresses core pain points of heavy-lid top-load washing machines:

• Weak damping at small closing angles
• High opening resistance
  It maintains effective damping near the closed position, solving the issue of lids slamming shut. It also provides lift-assist force, reducing opening effort for a smoother user experience.

Key specs include a 20–80 kgf·cm torque range, -20°C to 60°C operating temperature, POM housing, and PA66-GF40 rotating shaft for durability. Available in left/right-hand versions, it enables easy assembly, supporting large-volume production.

Trusted by brands like Whirlpool, Midea, Panasonic, and Samsung, the PR-T115G enhances lid motion control, boosting appliance safety, usability, and premium perception—directly elevating brand value for manufacturers.
