SUPPORT UNIT

Support Unit

SCREWTECH Automation

Offers nine series of ball screw support units: EK, EF, BK, BF, FK, FF, AK, AF, WBK

For shaft diameters 5–40 mm, ensuring high-precision, stable rotation of ball screws—from general environments to cleanrooms

Core Features

FULL COVERAGE

Nine Series · Shaft Ø 5–40 mm Full Coverage

Convex (EK/EF), square (BK/BF), round (FK/FF), compact (AK/AF), and heavy-duty (WBK); support and fixed sides pair up to meet diverse design needs.

DUAL SURFACE TREATMENT

Black-Oxide / Electroless-Nickel Finishes

Black oxide for general environments, electroless nickel for cleanrooms; bearings use dual iron-shield or dual plastic-shield sealing—two finishes cover all conditions.

PREMIUM BEARING

Brand Bearings · Preloaded, Maintenance-Free

Fixed side uses preloaded angular-contact ball bearings (JIS5/P0); support side uses deep-groove ball bearings. EK/BK/FK/AK types are pre-lubricated and specially sealed for long-term maintenance-free use.
