Product Features

Ultra-compact and lightweight design

Smaller outline dimensions and simplified structure, ideal for space‑limited equipment.

Integrated precision bearing housing

High concentricity and rigidity, ensuring stable running accuracy.

Fixed side (EK) and supported side (EF)

EK serves as the fixed side with high axial rigidity; EF acts as the floating side to compensate for thermal elongation of the screw shaft.

Preloaded high-performance bearings

Built-in precision angular contact ball bearings, enabling high-speed, low‑noise operation.

Standardized dimensions

High interchangeability, easy to install, adjust and replace.

Built-in sealing and lubrication structure

Effectively prevents dust and coolant contamination, ensuring long service life.
