Hardened Steel Rails for Heavy Duty Applications

Product catalog summary
Overview: The document provides technical specifications and options for SMITH-RAIL hardened steel rails, designed for heavy-duty applications in material handling systems. These rails are used in conjunction with SMITH-TRAX® bearings to facilitate the design and fabrication of precision systems.
Specifications: SMITH-RAILS are made from 180,000 PSI tensile strength steel, available in three profiles with a maximum length of 12 feet. The contact surfaces are hardened to 60-65 Rc to match SMITH-TRAX® bearings. They support maximum rail loadings of up to 71,500 lbs per roller. Rails are straight and twist-free, and can be customized in length and drilled for mounting as per specifications.
Mounting Options:
  • Option 0: No mounting holes.
  • Option 1: Clearance holes for cap screws, spaced 12 inches apart (300mm for metric).
  • Option 2: Clearance holes with counterbore for socket head cap screws, spaced 12 inches apart (300mm for metric).
  • Option 3: Tapped holes for cap screws, spaced 12 inches apart (300mm for metric).
Each option requires adding a specific suffix to the part number.
Profile Dimensions: The document includes detailed dimensions for various rail profiles (SRV, SRP, SRHP) and their corresponding mounting options, with specifications for both imperial and metric measurements.
Part Numbering System: The part number is determined by the rail profile, length, and mounting option. Lengths are specified in whole and fractional inches or millimeters. Examples are provided for both imperial and metric systems.
Customization: Customized rails are available in any length upon request, and the document encourages contacting the factory for specific needs.
