Various Models for Diverse Industrial Scenarios
Various models, suitable for diverse industrial scenarios
To meet the needs of different equipment and working conditions, we offer a rich product range, covering various installation methods and material options:
Cylindrical Retractable Spring Pin: A smooth cylindrical shell without threads, which can be directly pressed into the installation hole, suitable for workpieces and fixtures requiring interference fit. Made of stainless steel, it is wear-resistant and rust-proof, maintaining stable elasticity and positioning accuracy even under high-frequency extension and retraction actions.
Threaded Spring Indexing Pin: With external threads, it can be quickly locked in place through a nut, making disassembly and maintenance more convenient. Widely used in equipment indexing plates, fixtures, etc., where the positioning position needs to be frequently adjusted. Some models feature a brass shell combined with a stainless steel ball head, balancing conductivity and wear resistance, suitable for special usage requirements of electronic equipment.
Engineering Plastic Model Spring Loaded Retractable Pins: Using a chemically resistant engineering plastic shell and ceramic/nylon balls, it is lightweight and has good insulation properties, suitable for industries such as food, medicine, and electronics that are sensitive to metal contamination.
All products feature high-hardness stainless steel balls, combined with precisely machined springs, with smooth extension without jamming, and repeat positioning accuracy of ±0.02mm, ensuring precise and reliable positioning every time.
