Description


High-Rigidity Open-Type Linear Motion Unit Engineered for Stable, Smooth, and Long-Stroke Precision Movement
Product Overview
The TBR…UU Linear Slide Block uses an open-structure ball bearing design that allows the block to run directly on a supported linear shaft. The bearing’s internal double-row ball circulation provides smooth motion with low friction, while the aluminum housing greatly improves rigidity. This combination makes the TBR series suitable for systems that require high stability during long-stroke movement.
Key Features
High Precision Motion
With precision-ground ball bearings and optimized internal ball tracks, the TBR…UU block delivers consistently smooth, low-noise, and low-friction linear travel.
Enhanced Rigidity & Load Support
The rigid aluminum base reduces shaft deflection and increases load capacity, making TBR systems more stable than standard unsupported linear shaft systems.
Easy Installation & Alignment
Each block is designed with standardized mounting holes for quick integration into CNC machinery and automation frames.
Installation requires minimal adjustment, improving assembly efficiency.
Durable Bearing Steel Construction
The bearing components are made from hardened bearing steel, providing excellent wear resistance and long service life even under continuous-duty motion.
Wide Range of Sizes
Available models include TBR12UU, TBR16UU, TBR20UU, TBR25UU, TBR30UU, TBR35UU, TBR40UU, TBR50UU, and custom specifications to meet different machine requirements.
