This product is an ultra-thin metal washer used in high-precision mechanical and electronic assembly applications. The key features of these washers are their “extreme thinness, small size, and high precision” – typically with a thickness of only 0.03mm to 0.5mm and an outer diameter as small as a few millimeters. They ensure reliable mechanical support and positioning accuracy in microscopic assembly structures. Manufactured using high-precision stamping, turning, or chemical etching processes, they achieve thickness tolerances in the micrometer range, meeting the stringent requirements of precision assembly for "micro-gap compensation" and "precise positioning."
Structural features and advantages:
Ultra-thin design: Thickness can be as low as 0.03mm to 0.5mm, suitable for precision assembly in confined spaces.
High-precision dimensional control: The outer diameter, inner diameter, and thickness tolerances are strictly controlled within ±0.01mm, ensuring stable assembly.
Excellent flatness and surface quality: achieving Ra≤0.4μm, effectively reducing friction and wear.
Available in a variety of materials:
Brass: Excellent electrical conductivity and strong corrosion resistance, suitable for electronic contacts;
Carbon steel: High strength and good hardness, suitable for structural support and compression applications;
Stainless steel: Corrosion-resistant and high-temperature resistant, suitable for optical and medical instruments.
Optional surface treatments:
Nickel plating, zinc plating, oxidation, passivation, etc., to enhance rust resistance and wear resistance.
Main uses:
It is widely used in fields such as digital cameras, optical instruments, precision electronic products, communication equipment, medical devices, automated instruments, and miniature motors.
Digital cameras and optical lens assemblies: Used for lens group positioning, lens barrel gap adjustment, and optical axis correction.
Optical instruments and measuring equipment: Ensures balance and stability between lenses, prisms, and optical mounts.
Precision electronic and communication equipment: Used for circuit board support, conductive spacing, and heat sink component fixing.
Automation equipment and precision machinery: Adjusts assembly tolerances of mechanical parts and controls axial or radial clearance.
Medical instruments and precision testing equipment: Provides positioning in small drive units, miniature motors, or measuring heads.
Micro motors, drive systems, and transmission structures: Balances rotational accuracy and reduces vibration and noise.
These precision washers, although extremely small in size, play a crucial role in high-precision assembly. They are "seemingly insignificant yet indispensable" components, providing vital assurance for the stable operation and precision control of precision instruments!
