Motion Without Limits

SL2-Stainless Steel Based Slide System The HepcoMotion® SL2 system from Bishop-Wisecarver offers the user basic interchangeability with GV3 components1 consisting of stainless steel bearing assemblies, flat slides and spacer slides. A complementary range of light-weight aluminum carriage plates and flange clamps is also available, with special surface treatment providing corrosion resistance better than most stainless steels. This process is approved by the U.S. Department of Agriculture for use in food processing machinery. A variety of applications, including food processing and...

Motion Without Limits About Bishop-Wisecarver Corporation® Bishop-Wisecarver, a family owned manufacturing company incorporated in 1950, is the recognized market leader for guided motion technologies. In 1967, Bud Wisecarver invented and patented DualVee Motion Technology® (DMT) to provide a solution for harsh environment applications where existing technologies were ineffective. DualVee® also proved excellent for long length, smooth motion and low noise requirements. Three main components define DMT – the DualVee guide wheel, its mating vee profile track with patented mounting shoulder,...

System Composition SL2 offers excellent performance through a quality manufacturing process and careful selection of materials, and has been designed to provide the ideal combination of corrosion resistance and long service life even in the most arduous application. The SL2 range of slides is very extensive, comprising seven flat slide sections and four spacer slide sections. This very wide range ensures that the most suitable slide can always be specified for any application. All except the smallest are available in 4 meter lengths, ground on all main surfaces with hardened ‘V’ running...

Carriages can be supplied fitted with: Bearing Assemblies only - for dry or minimum friction applications Cap Seals - to shroud the bearing assemblies - for excellent lubrication and sealing quality Lubricators - for the application of lubricant with lower friction All components are available individually for customers who wish to construct their own carriage plates, or where the carriage may be part of the machine structure. All bearing assemblies are of stainless steel construction, in either twin bearing or double row format, and are supplied lubricated for life. They are hardened...

Application Examples Industrial Applications SL2 system is used for vertical and horizontal guidance on a bottle tilling machine in the cosmetics industry. Spacer slides are shown fixed to the machine structure on the horizontal axis. Short undrilled spacer slides are used on the vertical axis supported one end only by long type flange clamps. Carriage plates are shown used throughout. Alternatively, bearing assemblies and cap seals can be mounted direct to the moving components of the machine. Care should be taken to ensure parallelism of opposing slides during installation. Twin...

Motion Without Limits Scientific/Test Applications SL2 system is used for telescopic horizontal guidance in a nuclear industry drum handling application. Vertical movement is provided by a scissor lift. The environment experiences a low level of radiation. Therefore the bearing assemblies are supplied with special grease lubrication internally. Because the system is required to be all stainless steel, the standard coated aluminum carriage plates have been replaced by specials, manufactured to the customer’s drawings. External lubrication of the slides is not possible in this application....

Data & Dimensions Assembled Systems SL2 can be ordered as individual components or as a factory assembled system. Ready-assembled carriages are available with just the bearing assemblies fitted, or with the addition of either cap seals or lubricators (see Stock SL2 Carriage table, page 9). The following three pages show important reference dimensions between assembled components, as well as the maximum overall sizes of the assemblies. Other dimensions will be found on the pages relating to the specific components (10 - 17). Assembled Systems Incorporating Carriage Plates, Through Hole...

CONTINUED FROM PREVIOUS PAGE CONTINUED ON NEXT PAGE Notes (continued) 2. Customers constructing their own carriage plate should drill the bearing assembly hole centers according to ‘D’ dimension, to a recommended tolerance of ±0.2mm. Holes should be drilled and reamed to size and tolerance per ‘R’ dimension, page 15. 3. Although dimension ‘E’ is expressed as minimum values, it is recommended wherever possible to have E > D for rigidity purposes. Dimension ‘E’, Min CS and Min LB refer to the minimum bearing assembly spacing when customers are using Cap Seals (CS) or Lubricators (LB)...

Data & Dimensions Assembled Systems Blind hole fixing bearing assemblies are for use where access to the back of the mounting plate is not possible or where the thickness of the mounting plate prevents use of the through hole fixing bearing assemblies. These circumstances are not relevant to the use of carriage plates. Therefore systems using blind hole fixing bearing assemblies are not available factory assembled. Assembled Systems Incorporating Blind Hole Fixing Bearing Assemblies and Lubricators Blind Hole Fixing Bearing Assembly - Eccentric (see note 5 & page 13) Blind Hole Fixing...

Ordering Assembled Systems The table below shows the combinations of components available to make up a factory assembled carriage. Pages 10 to 17 detailing individual components will aid the selection of assembled systems, and will explain the relative merits of various component choices, e.g. cap seals versus lubricators, twin versus double row bearing assemblies. Once the component combination for an assembled system has been decided upon, the table below can be consulted for availability and a part number specified according to the table and the ordering details shown. Ordering Details...
