Prismatic Rail

Prismatic rails with bearings and induction hardened v-shaped raceways.

The Prismatic Rail family is composed of linear bearings sliding on V-shaped rails made of hardened steel. These linear guides with rollers also have high self-alignment properties.

V-shaped rails are induction hardened and polished, available in three sizes: 28, 35 and 55 mm. Antioxidation treatment is available upon request on every version. Rails can be machined with two straight cuts, one straight and one slanting cut or two slanting cuts. These options allow to create joinable versions, and thus obtaining longer strokes.

The aluminium slider can be configured with a variable number of rollers with steel pins, ranging from 2 to 6. Rollers are in turn available in two variants, cylindrical or V-shaped, with variable diameter from Ø30 a Ø62 depending on rail size.

Characteristics of Prismatic Rail linear bearings:

  • Long life thanks to hardened raceways
  • Optimal reliability in dirty environments
  • Self-aligning system
  • Simple mounting
  • High dynamics
