ANWOK Ballscrew SFU1605-1050mm with A Ball Nut - Antibacklash

In this review of the ANWOK Ballscrew SFU1605-1050mm, the bottom line is simple: this is a precision, low-noise ballscrew for machine builders and retrofitters who need accurate linear motion over a 41.33in travel. The reviewer found the unit useful where consistent axial force, reduced drive power and minimal stick-slip are priorities. Built from CF54 steel and finished with anti-backlash machining and standard BK10/BF10 end faces, it targets applications that demand durability and repeatable positioning rather than consumer-level price sensitivity.

Key Features

• Antibacklash design: The machined anti-backlash ball nut reduces end play for more accurate positioning and less stick-slip during slow moves.
• CF54 steel shaft: Durable material delivers good wear resistance for longer service life in industrial use.
• Low operating noise: The finished screw runs quietly, which helps when the assembly is exposed in small workshops or control cabinets.
• High transmission efficiency: The low friction profile converts rotary input to axial motion with reduced drive power and less heat buildup.
• Standard end machining: BK10/BF10 standard end faces and a coupler inner hole sized 6.35mm x 10mm simplify integration with common motors and couplers.
• Wide application range: The SFU1605 form factor is suitable for aerospace-style control actuators and automotive steering-type translation tasks in prototyping and light industrial systems.

Who It's For

The ANWOK SFU1605-1050mm is aimed at engineers, CNC hobbyists and machine builders who need a compact, accurate ballscrew with anti-backlash characteristics for positioning tasks up to 41.33in. It fits retrofit projects where a 16mm fixed side diameter and a 6.35mm x 10mm coupler hole match existing hardware.

It is less suitable for applications that require off-the-shelf complete actuators, integrated limit switches, or metric thread pitches outside the SFU1605 family. Buyers seeking the longest possible travel should note alternative lengths are available on request rather than relying on this single-stock length.

Pros & Cons

Pros

• Anti-backlash nut and precise machining give repeatable positioning and reduce end play.
• CF54 steel construction provides good wear resistance for sustained industrial use.
• Low operating noise and high transmission efficiency reduce heat and required motor power.

Cons

• Sold as the screw and nut assembly only; no integrated motor, bearings or limit switches are included.
• Length options exist but require contacting service for non-standard sizes rather than immediate selection.
