Arbitrary stop positioning: Stop at any angle you choose with smooth rotation for precise positioning and easy, controlled opening. Long service life: Rigorously tested for durability and capable of withstanding more than 5000 rotations with minimal damping loss. Thickened metal material: Made from carbon steel with nickel plating for strong, longlasting performance. Applications: Suitable for use in brackets, chassis cabinets, and automation equipment, making it a versatile choice for various projects. Use scenario 1: Install in adjustable brackets or machine covers where a precise stop angle is required for safe, predictable access. Use scenario 2: Integrate into chassis cabinet doors or panels to provide controlled, smooth opening with a reliable rest position. Use scenario 3: Employ in automation equipment to ensure a defined resting position for rotating components and to resist unintended movement when idle.
