THK Co., Ltd. FBW50110H+400L Slide Pack Heavy Load

Description:

The THK FBW50110H+400L Slide Pack is a heavy-load linear motion guide designed to provide smooth, low-friction linear travel while supporting higher loads and rigidity than the standard FBW series. It consists of one recirculating ball slider mounted on a 400 mm precision guide rail, delivering reliable linear motion and long service life in demanding industrial applications. Commonly installed in machine tools, industrial automation equipment, heavy-duty sliding mechanisms, packaging machinery, and material handling systems. Maintenance teams and system integrators use this slide pack for equipment repair, replacement, retrofit, and new machine construction.

Applications:

The THK FBW50110H belongs to the THK FBW Series Slide Pack heavy-load type. The "400L" designation specifies an overall rail length of 400 mm, while the assembly includes one slider with an effective travel (stroke) of 270 mm without seals. The FBW50110H was the original high-rigidity heavy-load design and has since been discontinued by THK in favor of the improved FBW50110XR series, which offers equivalent functionality with updated rail design.
