Introduction
TBR block is a new-generation lightweight linear motion component, designed with a high-strength aluminum alloy base and a precision-ground shaft, suitable for applications such as automation equipment, woodworking machinery, and packaging production lines. Its flange type structure supports multi-directional installation, and combined with a G6-grade precision shaft (hardness HRC58-64), it achieves a positioning accuracy of ±0.02mm.
product highlights
1.High Strength & Lightweight
Aluminum alloy housing reduces weight by 60% compared to steel sliders, while maintaining excellent torsional resistance.
High-carbon steel shaft is quenched to HRC58-64 with hard chrome plating, enhancing wear resistance by times 3
2.Precision Positioning
Guide rail precision class G6 with straightness error ≤0.02mm/m, ensuring accurate motion.
Four-row ball circulation design supports equal loads in four directions, with repeat positioning accuracy of ±0.005mm
3.Flexible Installation
Flange-type slider features through-threaded holes for bidirectional (top/bottom) installation, suitable for complex applications.
Compatible with SBR series sliders for interchangeability, reducing maintenance costs.
4.Longevity & Low Maintenance
Anodized aluminum rail resists corrosion in humid environments.
Built-in oil reservoir extends lubrication intervals to years, minimizing maintenance.

Secure slider with torque wrench (M6: 8-10N·m).
Adjust rail parallelism to ≤0.05mm/m.
2. Lubrication
Apply lithium-based grease (NLGI 2) before initial use.
Re-lubricate every 500 hours under high-speed operation.
3. Maintenance
Regularly clean rail surface to prevent particle wear.
Check slider clearance and replace ball components if necessary.
FAQ
Q1: How to select the right TBR block for my equipment?
A: Focus on shaft diameter and load requirements:
Small devices (3D printers, small engravers): Choose TBR16UU/20UU (Φ16/20mm shaft, load ≤1000N).
Medium machinery (woodworking, packaging equipment): Choose TBR25UU (Φ25mm shaft, load ≤2000N).
Heavy equipment (industrial robots, CNC machines): Choose TBR30UU (Φ30mm shaft, load ≤3000N).
Extended models TBRLUU are suitable for longer stroke needs.
Q2: What installation methods does the TBR block support? Any precautions?
A: It supports bidirectional (top/bottom flange) installation via through-threaded holes. Key steps:
Clean contact surfaces to remove debris for precision;
Tighten with a torque wrench (M6: 8-10N·m);
Adjust rail parallelism to ≤0.05mm/m for smooth motion.
