Units may be purchased assembled for quick installation, or as individual components for custom designs. V slides and flat tracks come in two grades; commercial for lower cost, or precision ground for higher accuracy applications. Gear racks can be added to single edge V slides and narrow flat tracks for linear actuation. Back plates offer another option for mounting V slides and flat tracks on a stable frame without the height of a construction beam. Bearing assemblies come in V slide bearings, track roller bearings, and bearing blocks to meet load and performance needs. Carriage plates are machined to customers' specifications from either steel or aluminum according to specific application needs.
HDS systems can be shipped as assembled units ready for installation. Mounting options include back plates and construction beam for V slides and flat tracks. Specify which guide type is required in each location, and the corresponding bearings desired. Additional accessories include gear racks and cap wipers, which increase the assembled unit's versatility and life, respectively.
V Slides and Flat Tracks
V slides and flat tracks are made from bearing quality carbon steel and hardened on wearing surfaces. The balance of the material is left in the annealed state to allow for additional machining. All V slides and flat tracks are available as a precision ground grade or as a commercial grade. The commercial grade is accurate enough for most applications, and is etched to allow for greater retention of lubrication along bearing contact surfaces. V slides are available as double edge or single edge. The single edge V slide can have a gear rack added. Flat tracks come in wide flat track and narrow flat track formats. Narrow flat tracks, like single edge V slides, can have a gear rack added.
Back plates allow for easy mounting of V slides and flat tracks, and may be used to directly mount to the customer's base, or to a construction beam. Back plates may be aligned using dowel pins or jacking screws. All back plates are made to tightly controlled tolerances from high strength aluminum alloy extrusion.
Depending on the carriage configuration, bearing assemblies can be purchased as through-hole fixing type (TH) or blind hole fixing type (BH). Through-hole fixing type bearings feature V slide bearings and track roller bearings in wide and narrow formats. Blind hole fixing type bearing assemblies allow the selection of the same bearing types as do through-hole fixing type bearings, but do not require through holes in the carriage. Neoprene seals are optional on any bearing type for additional protection against small particulates and liquids.
* When used with precision ground slides and tracks and properly lubricated.
Cap wipers provide optimal performance of systems by properly lubricating the interface between the V slide and V bearing. Cap wipers provide a grease reservoir for continuous lubrication during system life.
Extruded aluminum alloy construction beams enable slides and flat tracks to be factory assemled directly to the corner faces of the beam or to be mounted at the many T-slot positions in conjunction with back plates and T-nuts. Construction beams are available in three sizes; HB33, HB25, and HB25C, which has been designed to accommodate a screw drive.
T-Nuts, Pinions, and Carriage Plates
T-nuts, pinions, and assembled carriage units all add value to the HDS2 system by providing quick and easy means of attachment, actuation, and customization, respectively. T-nuts come in flush T-nut style, location T-nut style, and adjustment T-nut style to meet different requirements when mounting to the construction beam. Pinions are available as bored pinion and shaft pinion for mounting versatility.Assembled carriages for all sizes of bearing are available to fit all sizes of beam incorporating corner mounted slides. Carriages are also available to fit double edge slides. Carriages are supplied with through hole fixing bearings to facilitate direct removal from the slide. Cap wipers and lubricators are available as options.
