About this item

This kit gives you everything needed to build a precision linear axis: two 1200mm HGR20 guide rails with four HGW20CC carriage blocks, and a 1200mm SFU1605 ballscrew with matching ball nut. It comes complete with a DSG16H nut housing, BF12/BK12 end supports, and a 6.35x10mm coupler sized for a 6.35mm motor shaft. Made from Gcr15 steel with a chrome-plated finish, the assembly runs smooth and quiet while holding C7-grade accuracy — ideal for CNC routers, lathes, and other automated machinery. Mounting screws (M5x6mm) are included for easy installation.

Complete CNC linear motion kit: 2x HGR20 guide rails (1200mm) with 4 HGW20CC blocks, plus 1x SFU1605 ballscrew (1200mm) with ball nut
Ballscrew specs: 16mm diameter, 5mm lead, C7 accuracy grade for precise, repeatable positioning
Includes DSG16H nut housing, BF12/BK12 end support set, and a 6.35x10mm coupler (D25 L30) for 6.35mm motor shafts
Built from Gcr15 bearing steel with chrome-plated surface, hardness up to HRC62 for long service life
Smooth, low-friction ball movement avoids stick-slip creep, giving accurate positioning with less heat and lower drive power
Suited for DIY CNC routers, lathes, bending/laser machines, and other automation equipment needing precise linear travel
