What is Supported Linear Shaft?
Supported Linear Shaft, also known as SBR or TBR linear guide rail, is a precision round shaft mounted on a full-length aluminum support base. This design prevents shaft deflection, enhances rigidity, and ensures stable linear motion over long spans, making it ideal for CNC machines, automation equipment, and other industrial applications.
DLY is a direct manufacturer of supported linear shafts, supplying standard SBR and TBR models in bulk with consistent quality, fast delivery, and custom machining services for distributors, OEMs, and industrial buyers worldwide.
