For the bearing journals that are ground, we achieve a bearing fit of diameter tolerances of ±0.0002 inches. Straightness tolerances of 0.001 inches per foot to prevent vibration is achieved, total indicator runout (TIR) tighter than 0.0005 inches for proper balance during rotation, concentricity of 0.0002 inches is achieved over multiple diameters for proper alignment, and surfaces of the bearings are finished to 0.4 Ra microns to reduce friction, while keyway dimensions are ensured to be within ±0.002 inches for proper coupling fit.

For shafts with varying profiles and multiple diameters, shoulders, and threads, Precision CNC turning within concentricity of 0.0002 inches is used. Tight diameter tolerances of ±0.0002 inches, straightness tolerances of 0.001 inches per foot, and surface finishes of 0.4 Ra microns are achieved on bearing journals through centerless grinding. Internal and external spline cutting to pitch precision is attained through spline cutting and hobbing. Control and precision are exercised in exaggerated key slot milling. Through induction hardening, selective surface hardening to 50-58 HRC on bearing and gear mounting areas is possible. Precision threads to specification are achieved through thread grinding. Hard chrome plating bearing journals are extending the wear life of the journals.

Automation shafts are components which passes on torque and aids in the rotation of robotic drives and motion control systems actuators. They are designed for the purpose of rotation with accuracy. There are different types of motor shafts (that join armatures to loads), splined shafts (that offers positive torque transmission), keyed shafts (that have key slots for coupling which are attachments on the opposite side), hollow shafts (that reduces weight and also allows through-shaft cabling), step shafts (that have multiple diameters for bearing and gear mounting) eccentric shafts (that creates reciprocating motion), cam shafts (for timing automation), drive-shafts (for high torque) and precision ground shafts (that mounts encoders and resolvers requiring minimal runout).
