TOCO ETH Series Linear Guide Block | High-Precision Square Flange Carriage

The TOCO ETH series guide carriages are designed for industrial precision and heavy-duty reliability. Featuring a square-type flange and a robust recirculating ball system, this block provides smooth, low-friction motion for high-end automation and CNC applications.

Key Features:

  • High Load Capacity: Engineered to handle heavy dynamic and static loads with ease.

  • Four-Way Equal Loading: Delivers consistent performance by absorbing loads from all directions (top, bottom, and sides).

  • Self-Aligning Capability: Minimizes friction and compensates for minor mounting misalignments.

  • Superior Dust Protection: Integrated end seals protect internal bearings from dust and debris.

  • Durable Construction: Made from high-carbon bearing steel for maximum longevity.

Technical Specifications:

  • ETH15CA – 15mm Rail Size | Square (Low Profile) | High Load / Standard Block

  • HTH20CA – 20mm Rail Size | Square (Low Profile) | High Load / Standard Block

  • ETH25CA – 25mm Rail Size | Square (Low Profile) | High Load / Standard Block

  • ETH30CA – 30mm Rail Size | Square (Low Profile) | High Load / Standard Block

Full Assembly Model Nomenclature

If you are looking at a full part number for a complete assembly (rails + blocks combined), TOCO expands the code into a longer string to dictate customization.

An example of a full model configuration code looks like this:

ETH25 CA 2 R 1000 - Z0 C - 20/20

Here is exactly how to decode that full assembly number string:

  • ETH: Series Designation (Low Profile, Square Carriage)

  • 25: Nominal Rail Width / Size (15, 20, 25, or 30 mm)

  • CA: Carriage Length/Load Code

  • 2: Number of blocks mounted on a single rail (e.g., 1, 2, 3...)

  • R: Signifies the Rail component

  • 1000: Total length of the linear rail (in mm)

  • Z0: Preload Code (ZF = Slight Clearance, Z0 = Zero Preload, Z1 = Light Preload)

  • C: Accuracy Classification (C = Normal, H = High, P = Precision)

  • 20/20: The pitch end distances (E1 / E2 hole placement in mm)

Ideal For:

  • CNC Routers and Milling Machines

  • Industrial Robotics and Automation

  • Precision Measuring Instruments

  • Packaging and Sorting Machinery

Note: Linear rails are sold separately.
