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.
