Rollon bearings presents telescopic rails. These rails are used in fields where high load capacities, reliability, low deflection and smoothness of movement are important. Hardened raceways guarantee that the slides offer smoothest and stiffest movement, even under maximum capacity with the least amount of deflection. In addition, they ensure that the slides work well even with vibrations. These telescopic rails find wide application in train battery extraction, vehicle handicap step, electromedical beds, product exposition units, telescopic press arms, etc.
