Dual Rod Guided Air Cylinder

XCTR double rod pneumatic cylinders integrate the guide function directly into the cylinder body, eliminating the external guide rail most side-load applications would otherwise need. Bore Ø6–Ø32mm, three rotation accuracy grades, multi-surface mounting.

Product Introduction

Skip the External Guide Rail Entirely

The usual way to give a cylinder side-load resistance is to add a guide rail alongside it - a separate component to source, align to the cylinder's travel, and maintain as a second wear surface over the machine's life. XCTR takes a different approach: the twin-rod structure that drives the load is also what guides it, so the guiding function lives inside the cylinder body instead of bolted on next to it.

For machine builders, that mostly shows up as a simpler bill of materials and a faster build: one part instead of a cylinder-plus-rail assembly, one alignment step instead of two, and one component to maintain instead of a pair that can drift out of alignment relative to each other over time.

Three Rotation Accuracy Grades, Not One Fixed Spec

Most guided cylinders publish a single accuracy figure and leave it at that. XCTR is rated across three tiers - ±0.2°, ±0.15°, and ±0.1° - which means the accuracy level can be matched to what the application actually needs rather than over- or under-specifying a single fixed tolerance.

That matters because tighter tolerance typically comes with a cost and lead-time tradeoff. An application that just needs to keep a workpiece from rotating during a transfer doesn't need the same guarantee as a precision assembly fixture - XCTR's tiered rating gives you room to match the spec to the job instead of defaulting to whichever single number a simpler product line happens to offer.

Multi-Surface Mounting for Retrofits and Tight Layouts

The mounting plate includes hole patterns for top, bottom, and side mounting, so the same cylinder can be installed in whichever orientation the surrounding machine structure actually allows - useful when retrofitting into an existing frame where the "ideal" mounting face isn't necessarily the one that's accessible.

Combined with flexible air port routing (multiple port position options rather than one fixed configuration), XCTR is built to fit around existing machine geometry rather than requiring the machine to be designed around it.

Where XCTR Is Typically Used

Retrofit and space-constrained builds - where multi-surface mounting lets the cylinder fit an existing frame rather than requiring a redesign.
Applications currently using a cylinder-plus-external-guide setup - where consolidating to one integrated component simplifies the bill of materials and installation.
Tasks with varying precision requirements across a product line - where the three rotation accuracy tiers let the same base cylinder cover both loose-tolerance transfer work and tighter-tolerance positioning without switching product families.
General automation - assembly machines, positioning systems, material handling, feeding mechanisms, and clamping devices where side-load resistance without an external rail is the deciding factor.

Frequently Asked Questions

What makes XCTR different from a cylinder with an external guide rail?

The guiding function is built into the twin-rod structure itself, so there's no separate guide rail to source, align, or maintain - one integrated part instead of a cylinder-plus-rail assembly.

What do the three rotation accuracy ratings mean?

XCTR is available across three accuracy tiers (±0.2°, ±0.15°, ±0.1°), letting the tolerance be matched to the application rather than defaulting to a single fixed spec. Confirm the specific ordering code for your required tier when specifying.

Does XCTR eliminate the need for external guides in every application?

In many applications, yes - the integrated twin-rod structure provides the guiding function directly. For very heavy or highly off-center loads beyond the rated capacity, an external guide may still be worth evaluating; share your load conditions for a specific recommendation.

What mounting orientations are supported?

Top, bottom, and side mounting, using a plate designed with multiple hole patterns - useful for fitting into existing machine structures rather than requiring the equipment to be built around one fixed orientation.

What bore sizes and stroke ranges are available?

Six bores from Ø6 to Ø32 mm, with stroke ranges up to 200 mm depending on bore (see the stroke table above), plus a 0–5 mm fine adjustment for final position tuning.

[Note] For non-standard strokes within the 100mm range, increments are set at 5mm; these units are modified from the next higher standard stroke, and their external dimensions match those of the cylinder with that higher standard stroke. For example, a cylinder with a non-standard stroke of 35mm is modified from a standard cylinder with a 40mm stroke, and its external dimensions are identical to the latter.
