LDA Series ID/OD Adjustable Frame
Our most popular series of ID/OD gage uses rigid steel tubing, cast end blocks, and a precision right angle transfer mechanism similar to our bore gages which gives accurate and sensitive readings.
> Gage is shown with optional .0001" graduation dial indicator, part # 2I50-01.
LDA Series Features:
- Standard with part# 2DM125-05 .0005" graduation dial indicator
- Rigid steel tubing with thermal isolation grips, reduces thermal expansion. Tube weighs only 1.165 lbs/foot
- Indicator and housing rotate 360° for best viewing angle
- Entire assembly rotates 180° for ID/OD measurement
- Three point hardened steel rests
- Reference contact features .50" micrometer style fine adjustment which makes setting this gage fast and easy
- 2" vertical gaging depth adjustment on head assembly is standard. 3", 4", or 5" is optional
- .100" gaging travel on live contact is standard, .025", .050", or .075" travel is optional
How to order:
To order large diameter gages, use following sequence to specify the desired configuration (there's no need to specify configuration for standard items).
Gage Type - Frame Size - Contact Type - Gaging Depth - Other Options
For example: LDA-24-ES-GD3-RR-GC050 is a gage that measures 18 - 24", includes extended carbide shovel contacts, has 3" gaging depth, has roller rests and gaging contact travel is limited to .050".
Standard gaging depth range is 0-2". Optional gaging depth of 3", 4" or 5" is available. Specify GD3, GD4 or GD5 to the part # (and use SMVA setmaster).
Standard LDA frame clearance is 1.25". Contact us for a quotation if additional clearance is required.
To order roller rests, add "-RR" to the part #.
Standard gaging contact travel is .100. Optional travel of .025, .050 or .075. Specify GC025, GC050 or GC075 to the part #.
Straddle reference rest is used when the rest and check diameter interfere SRR for rest and extended contact.
