Description


High-Rigidity Open-Type Linear Motion Unit Designed for Smooth, Stable, and Long-Stroke Precision Guidance.
Product Overview
The SBR…UU sliding block uses a double-row ball bearing structure, allowing the block to move smoothly along the supported shaft with minimal friction. The integrated support base increases rigidity and reduces deflection, making SBR units ideal for applications requiring stable and accurate linear travel.
Key Features
High Precision Motion
The SBR…UU block maintains smooth linear motion with low noise and low friction due to precision-ground bearing components.
Strong Load Capacity
Supported rails reduce bending, enabling higher load capacity compared to unsupported shaft systems.
Easy Installation
The aluminum support base includes pre-drilled holes for fast mounting on machine frames and automation equipment.
Durable Steel Bearings
Each block contains hardened steel balls and raceways that provide excellent wear resistance and long service life.
Multiple Sizes Available
SBR12UU, SBR16UU, SBR20UU, SBR25UU, SBR30UU, SBR35UU, and custom lengths are available to fit different machinery requirements.
Typical Applications
The SBR…UU linear sliding unit is commonly used in:
CNC machines and automation equipment
3D printers and DIY machinery
Packaging and cutting machines
Industrial robots and assembly lines
