Product Description

0.875TH Series SMR Adapter

For use with 0.875″ diameter SMR

The 0.875TH series of magnetic adapters provides an SMR nest which mounts in holes having diameters from 1/8″ to 5/8″ or from 4 mm to 15 mm. Shank diameters are held to very close tolerances for precision slip fits. The adapter holds the center point of a 0.875″ diameter SMR on centerline of the shank to a tolerance of ±0.0005″ (±0.013 mm). The adapter also holds the center of the SMR to a known offset height at a tolerance of ±0.0005″ (±0.013 mm). Refer to the table below for the available offset and shank diameter combinations. Choose any “A” value from the table below, and pair with any “B” value (table at right, below) to create the item number for the product that you want. For example, 0.875TH-.5-12MM.
