Technical Data:
Series: 215
Product: Cast Iron Base Comparator Stand
Anvil: 150 x 150 mm square semi-serrated anvil
Clamping range on column: 0 to 275 mm
Micromotion mechanism: Micromotion screw
Stem hole: Dia.20 mm; Dia.0.375 in with bushing; Dia.8 mm with bushing

Application:
Designed for comparison measurements of size using a dial indicator or Digimatic Indicator.
Semi-serrated anvil prevents very flat workpieces from wringing to it.

Dimensions:
Anvil flatness: 2.3 um or better. Drawing dimensions: 150 mm; 255 mm; 179 mm; Dia.50 mm; 115 mm; 400 mm; 64 mm; 100 mm.

Remark:
Perpendicularity of stem hole to anvil is better than 0.4 mm/100 mm.
High-accuracy Linear Gages with resolution 0.1 um or better may be affected by mounting-hole perpendicularity due to cosine effect.
Compact dial indicators with bezel Dia.31 mm or Dia.36 mm are not suitable.

Optional:
21JAA331: Dia.15 mm bushing; catalogue states for 215-156-10 and 215-505-10.
