Miniature MR rails with a size of as little as 2 mm are available for the miniature guide rails. Miniature guides are made in three accuracy classes: precise (P), high (H) and normal (N). The series of miniature MR rails can be divided due to the width of the guide for narrow and wide, and for short and long trucks.
Various types of seals are available for all sizes of the carts, enabling the designers to choose the most optimal fit for their application. Miniature MR series guides are composed of a 2-row ball system.
The balls move on a gothic profile track with a 45-degree contact angle, which allows the truck to be equally loaded in all directions. This design also provides more space for larger rolling elements, which improves load capacity and the ability to transfer sharply moments.
