Configuration Guide

How to choose within this collection

Step 1: Choose technical variant

Type I and Type II stay on separate series paths where the integration interface differs.

Step 2: Choose frame size

Frame size narrows the size-level product family. Larger sizes do not always carry the same ratio set as smaller sizes.

Step 3: Choose ratio

Ratio options filter the public SKU workspace and update the known torque, speed, backlash and weight context.

Step 4: Open exact size page

The size page carries the lowest public product context for variant selection, controlled files and RFQ review.

SKU Selection Workspace

Filter by frame size, technical variant, and ratio

Use the data-backed filters to reduce the matrix to matching public SKUs. Each row links to one size-level product page for controlled file and RFQ review.
