Features

・Combineation of aluminum hubs and a polyacetal slider to handle shaft diameters up to φ35.
・High-precision slider groove for light press-fitting and zero backlash, enabling servo operation.
・Sliders can also be made of chemical-resistant or heat-resistant materials.

・Key groove shape complies with new JIS standards.Special key grooves should be shown in separate drawings.
・For d1 and d2,ordera for hole diameters other than the standard values can be made.
・Feel free to consult us about custom orders.
・Combinations of set screw and clamp styles can also be costomized.
