The accurately located shoulder provides for positive positioning, re-positioning, or replacement. • Material: Type 440-C Stainless Steel hardened to Rc 58-62 • Eccentricity, ball to shank, 0.0002 T.I.R. maximum • Two Piece Welded Construction B Part A +0.0000 C Number ±0.0001 -0.0003 ±0.005 29001 0.2500 0.1247 0.560 29002 0.3750 0.1872 0.750 29003 0.5000 0.2497 0.940 29004 0.6250 0.3122 1.060 29005 0.7500 0.3747 1.250 29006 0.8750 0.4372 1.440 29007 1.0000 0.4997 1.620 *Metric available if requested Tooling Balls • Material: Type 440-C Stainless Steel hardened to Rc 58-62 • Eccentricity, ball to shank, 0.0002 T.I.R. maximum • Two Piece Welded Construction Checking Balls (with reference shoulder and tapped shank) This Checking Ball can be pulled into a hole or bushing from below without applying pressure on the ball (accomplished by using a cap screw in the tapped hole in the shank). • Material: Type 440-C Stainless Steel hardened to Rc 58-62 • Eccentricity, ball to shank, 0.0002 TIR max. • Two Piece Welded Construction Part Number 29021 NOTE: The weld between the ball and the shank is made so that the ball will drop off if subjected to unusually heavy lateral forces. This prevents setup and inspection errors that might occur because of accidental bending of the shank. Fixture Balls (plain shank) These Tooling balls are assembled by a welding technique that retains the initial high precision and fine finish of the balls. *29010 is supplied with tungsten carbide ball only, with Rockwell hardness 91.5 - 92.5 **Metric available if requested B Part +0.0000 C D Number A -0.0002 ±0.0002 -0.005 *29010 0.1250 0.1255 0.0938 0.375 29011 0.2500 0.1247 0.2000 0.560 29012 0.3750 0.1872 0.3000 0.750 29013 0.5000 0.2497 0.4000 0.940 29014 0.6250 0.3122 0.4500 1.060 29015 0.7500 0.3747 0.5000 1.250 29016 0.8750 0.4372 0.6000 1.440 29017 1.0000 0.4997 0.7000 1.620 29003 TOOLING BALLS FIXTURE BALLS (PLAIN SHANK) PG 2.29 PART NUMBER A ± .0001 B +.0000 -.0003 D ± .005 29001 .2500 .1247 .560 29002 .3750 .1872 .750 29003 .5000 .2497 .940 29004 .6250 .3122 1.060 29005 .7500 .3747 1.250 29006 .8750 .4372 1.440 29007 1.0000 .4997 1.620 D Ø B ØA 29013 CHECKING BALLS WITH REFERENCE SHOULDER PG 2.29 PART NUMBER A B +.0000 -.0002 C ± .0002 D ± .005 29010 .1250 .1255 .0938 .375 29011 .2500 .1247 .2000 .560 29012 .3750 .1872 .3000 .750 29013 .5000 .2497 .4000 .940 29014 .6250 .3122 .4500 1.060 29015 .7500 .3747 .5000 1.250 29016 .8750 .4372 .6000 1.440 29017 1.0000 .4997 .7000 1.620 C D ØB A DIM 1/8 thru 5/8 ±.00002 3/4 thru 1" ±.00005 Ø.5000 ±.0002 .3125 ±.0002 .96 Ø.2499±.0001 Ø1/2" 6-32 UNC-2B TAP 3/16 DEEP
