Linear optical axes, as fundamental and crucial linear motion components, are primarily classified based on their core structural features and dimensional standards to meet the diverse needs of different applications regarding rigidity, weight, cost, compatibility, and installation methods.
The core classifications are as follows:
By Core Structure
Solid Linear Optical Axles: Such as the HS/SF series (metric) and SI series (imperial). Made from solid round steel through precision machining and hardening, they possess excellent rigidity and load-bearing capacity, with a robust structure. They are the most widely used and versatile standard optical axes.
Hollow Linear Optical Axles: Also known as the SP series. Manufactured using hollow tubing, their core feature is lightweight design. While ensuring sufficient rigidity, they significantly reduce the weight of moving parts and provide space for internal cabling, air pipes, or the installation of other components. They are suitable for weight-sensitive or integrated wiring applications such as automation equipment and robotics.
By Dimensional Standards
Metric Standard Optical Axles: Such as the HS/SF series (solid) and SP series (hollow). Its key dimensions, such as diameter and tolerances, adopt the internationally recognized metric (millimeters) standard, which is currently the mainstream choice in the domestic market, facilitating compatibility with most domestic and international mainstream brand linear bearings, supports, and other accessories.
Imperial Standard Optical Shafts: Also known as SI series (solid). Their key dimensions, such as diameter, adopt the imperial (inch) standard, primarily serving applications requiring direct replacement and compatibility with specific imported European and American equipment, existing designs, or special components.
The selection of linear optical shafts first requires a trade-off between the high rigidity of solid shafts and the lightweight of hollow shafts, and then specification matching based on the design standard system (metric/imperial) of the equipment to ensure optimal performance adaptation and installation compatibility.
