About This Product

■What is a friction fastener?

Friction fasteners are mechanical elements used to connect the rotating shafts of various industrial machines to pulleys, gears, etc. Friction fasteners are also called keyless bushings depending on their use, and are widely used in industrial machinery, machine tools, semiconductor manufacturing equipment, food machinery, etc. Typical methods include the wedge method (mechanical method), which uses the wedge principle, and the hydro method (hydraulic method), which uses Pascal's principle. By understanding the characteristics of each type well and incorporating friction fasteners that match the purpose and location of use, we can demonstrate various powers such as reducing man-hours and improving maintainability.

■Types and characteristics of friction fastening methods

- Wedge method (mechanical method): Cheap and highly versatile, but requires time and effort to install and remove. ・Hydro system (hydraulic system): Although slightly more expensive than the wedge system, it is easy to maintain, and installation and removal are easy, quick, and highly accurate.

■Features of the ETP-A model

The shaft and hub can be connected easily and quickly by tightening the clamping bolts placed on the flange surface. It can be tightened with fewer bolts than the mechanical type, and since there are no slots like the mechanical type, it is possible to connect with concentricity of 0.05 and high precision.

■A wide variety of variations

Steel is standard, and there are many variations such as simple anti-corrosion specifications, stainless steel specifications, and short specifications.
