Heavy Duty Ball Bearing Linear Slide SDC43N-0690-290 C-Shaped Guide Rail 43x690mm, 290mm Internal Carriage

Ball bearing linear slide with a 43mm width, 690mm length and 290mm internal carriage for high-load guided motion with a maximum stroke of 350mm. This SDC Series linear guide uses hardened steel drawer slide technology in a fixed C-shaped rail profile, keeping the internal carriage captured inside the rail rather than telescoping outward like a full-extension drawer slide. A precision ball cage assembly travels between the carriage and rail surfaces, usually about half the carriage distance, providing low-friction bearing action and guidance while distributing load through the steel balls. The enclosed C-shaped geometry helps protect internal components from debris and keeps motion contained within the rail envelope, making this slide well suited for large platforms, heavy access doors, robotics staging systems, machine access systems, and modular motion designs requiring high load capacity, durability, and controlled linear travel.
