Smooth operation with arbitrary stop positioning: The damping shaft rotates smoothly to the desired angle, enabling precise control with minimal effort. Longlasting reliability: Tested for 5000 rotations with damping loss staying under 20%, providing dependable performance over time. Sturdy metal design: Thickened carbon steel core with nickel plating for strength and durability. Wide application range: Suitable for brackets, chassis cabinets, and automation equipment. Use scenarios 1) Equipment enclosures and control panels: install on doors or access flaps to prevent slams and allow controlled, adjustable opening angles. 2) Industrial automation assemblies: integrate into moving brackets or guide arms to provide smooth, repeatable damping and precise stops. 3) Chassis and rack systems: use in chassis cabinets to hold lids at userfriendly angles for maintenance and operation.
