1100-48 Heavy-Duty Dial Indicator Diameter Gage 53138

Dial Indicator Diameter Gages measure both outside and inside diameters by comparing dimensions to gage blocks or an adjustable setting master. Each gage consists of a strong rectangular box beam with a sensitive gaging contact at one end and a reference gaging contact at the other. The 1110 gages combine heavy-duty construction features with adaptability for a wide range of internal and external measurements. The adjustable dowel rest legs ride on slotted mounting plates for horizontal adjustment. Each of the legs are vertically adjustable to obtain the proper rest position on the work and correct alignment on the gaging contacts. 2" or 50 mm range vertical adjustment. Radiused gaging contacts. The indicator can be rotated through to 360 Deg for a convenient gage should be checked against our 1126 Master for a precise reference standard during production gaging. Range: 42-48", Graduation: .0005"

  • There are two gage feet at the reference end and one foot at the sensitive end of the gage to set the gage on the work and align the contacts
  • Gage depth is set by adjusting the gage feet up or down
  • A lever-actuated reverse mechanism loads the gage for either inside or outside diameter measurements
  • The gage contacts are easily changed to I.D. or O.D. gaging by turning them end for end
  • Unless otherwise specified, the dial indicator sent with the gage reads in .0005" increments with a total range of +/-.030"
  • The dial has a double row of graduations reading in opposite directions - minus in red and plus in black
