Precision vs. Compensated Mini-Rail® Linear GuidewaysMini-Rail Compensated vs Precision

Mini-Rail® Miniature Linear Guides are available with two classes of running clearance in all sizes.  The 7, 9, 12, 15, and 20mm rails are all available in either a precision version for tighter tolerances or compensated version to tolerate greater misalignment.

  • Precision Mini-Rail Linear Guides
    • Use the prefix “MR” in the carriage part number  (MR12C)
    • Has the tightest running clearance (.025 - .051mm)
    • Recommended for applications that require tighter tolerances and stiffened assemblies
    • Not recommended for parallel shaft applications where misalignment can lead to binding issues.

 

  • Compensated Mini-Rail Linear Guides
    • Use the prefix “MRC” in the carriage part number  (MRC15C)
    • All dimensions are the same as the precision carriages except the running clearance (.064 - .089mm)
    • Ideally suited for parallel shaft applications because of increased ability to deal with misalignment and eliminate binding issues.

The precision vs. compensated feature is utilized in the Simplicity® round shaft self-lubricating linear bearings providing the same performance characteristics and ability to handle shaft misalignement.
