Description:
The C-Beam Linear Actuator Bundle Kit (400mm Profile) is a heavy-duty, precision linear motion sliding table designed for CNC routers, 3D printers, and industrial automation equipment. Constructed around a C-Beam aluminum extrusion (C-profile 40mm x 80mm), this linear module embeds the lead screw within the structural channel for added protection and compact performance. Driven by an ACME T8 lead screw rod, it offers an effective travel stroke of 308.85mm. The kit includes aluminum end mounts, a gantry plate mounted on smooth v-wheels, an anti-backlash nut block, and a 5mm to 8mm flexible shaft coupler for standard NEMA 17 motor integration.
Key Features:
- Concealed Lead Screw Structural Design: Utilizes C-shaped 40x80mm aluminum extrusion, housing the lead screw internally to prevent debris buildup and save space.
- 308.85mm Travel Stroke: Features a 400mm extrusion length providing 308.85mm of effective travel distance.
- Adjustable Tension Lead Screw Nut Block: Incorporates an adjustable anti-backlash nut block to maintain tension and eliminate axial play.
- Heavy-Duty Aluminum Gantry & End Mounts: Precision-machined aluminum gantry plate (77.15 x 77.15 x 6mm) and end mounts for rigid construction.
- Flexible Shaft Coupler Included: Comes with a 24.5mm x 19.5mm flexible coupler (5mm to 8mm bore) for standard stepper motor shaft attachment.
