The accurately located shoulder provides for positive positioning, re-positioning, or replacement. • Material: Type 440-C Stainless Steel hardened • Eccentricity, ball to shank, 0.0002 T.I.R. maximum • Two Piece Welded Construction Tooling Balls • Material: Type 440-C Stainless Steel hardened • 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 • Eccentricity, ball to shank, 0.0002 TIR max. • Two Piece Welded Construction 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 ne nish of the balls.
