There are clear standards for mechanical parts and components, including Chinese National Standards (GB), American Institute of Mechanical Engineers (ANSI/ASME), and other Japanese (JIS), German (DIN), and other standards widely used around the world. Mechanical components and parts with high standardization and strong industry universality are also known as universal parts. Generalized standard components include fasteners, connectors, transmission components, seals, hydraulic components, pneumatic components, bearings, springs, etc., all of which have corresponding national standards and strong cross industry universality.
Industry standard parts are a commonly accepted term within the industry and are not explicitly defined. Common industry standard parts include mold standard parts, automotive standard parts, etc. When a product is widely used in the industry, it is a universal component; General component standards are usually formulated by industry leaders and widely accepted within the industry, making enterprise standards the de facto industry standards, which can be referred to as industry standard components.
