Cross-Roller Guide Lineup Expanded with New Center Rail Type

THK CO., LTD. (Location: Minato, Tokyo; CEO: Akihiro Teramachi; hereinafter referred to as “THK”) has expanded its lineup of Cross-Roller Guide with Cage Alignment System products, adding a center rail type as a regular catalog offering in addition to the standard type.

Cross-Roller Guide Lineup Expanded with New Center Rail Type

The lightly moving cross-roller guide is a finite stroke linear guide composed of precision rollers held in an orthogonal orientation by a cage that is assembled onto a dedicated rail. This product achieves accurate motion and maintains cage alignment through the use of THK's proprietary rack and pinion system. It is suited for use in semiconductor and other electronic component manufacturing equipment as well as optical measuring instruments, and a high level of demand is expected in fields even beyond traditional OA equipment and peripheral devices.

The standard type allows customers to freely design how far apart each rail is installed, and this type has been the main focus up to now. However, we have now added a new center rail type* that simplifies installation and keeps equipment compact. Compared to the current Model VR, this product has more rollers, drastically improved basic load rating and rigidity, and a longer service life.
* The center rail type combines the two inner rails of the standard type into one.

To meet a wide range of needs, we will significantly expand our cross-roller guide lineup with a diverse array of models for both our standard and center rail types.

We will continue to develop and supply products that meet the needs of a variety of fields and contribute to heightened levels of performance in a broad range of equipment.

Features

Prevents cage misalignment

THK’s proprietary rack and pinion mechanism prevents cage misalignment caused by impacts and the vibrations and inertia of running equipment.

Standard type has interchangeable dimensions with the Model VR

The standard Cross-Roller Guide with Cage Alignment System can easily replace the current Model VR, as it has the same mounting dimensions.

Center rail type reduces installation work and makes equipment more compact

The center rail type combines the two inner rails of the standard type into a single rail.
This makes installation easier and allows for the construction of a table unit with a more compact width.
