The Single Edge format allows two Slide V’s to be mounted wide apart, thus providing a considerable increase in moment load capacity, stiffness and stability. The space between the two Slides can be made sufficient to allow central positioning of the drive, whether by means of ball screw, air cylinder or other type of actuator.
Single Edge Spacer Slides are available with a rack cut into the back face, providing a convenient means of driving. Rack teeth are machined to a high degree of precision and conform to ISO 1328 grade 8. The large face width of the racks makes these the best choice for applications which require high driving forces (see drive Calculations). Pinions which suit the Racks are also available. Shaft type pinions can be coupled directly to the UBM Geared Motor or Gearbox, which can be mounted using the Drive Flange to the customer’s own carriage plate.
Although not hardened, the rear face of the Slide is sufficiently durable to act as track for UBM Track Rollers.
