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.

Long service life and high rigidity

Compared to the current Model VR, the Cross-Roller Guide with Cage Alignment System has more rollers and drastically improved basic load rating and rigidity.

Interchangeable mounting dimensions

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

Structure of the Cross-Roller Guide with Cage Alignment System

This lightweight, finite stroke linear guide product is composed of precision rollers held in an orthogonal orientation by a cage that is assembled onto a dedicated rail. As a result, it can bear loads in every direction. It also has a high degree of rigidity and, being made of stainless steel, is extremely corrosion- resistant. Additionally, this product achieves accurate motion and maintains cage alignment through the use of a rack and pinion system.

Lineup

Standard type

The standard type can replace the Model VR because their mounting dimensions are interchangeable. It can also be installed with the desired spacing, making it a product that offers a high degree of design flexibility.

Center rail type

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.
