- Starrett S668CZ is a shaft alignment clamp set that includes two chain clamps, two Starrett 196B5 back-plunger dial indicator gauges, two stainless steel snugs to hold the gauges in measuring position, two extension plates for extra radial clearance and 3/8 inch diameter, stainless steel indicator posts (5, 7-7/16 and 9 inch lengths.
- The indicator gauges are used to measure alignment distortions and have a configurable armature to secure the gauges in position on two axes.
- The two chain clamps have a black, anodised aluminium frame with heavy-duty roller chains to secure the clamp around a shaft, and can accommodate shafts up to 7.5 inches in diameter. The excess chain can be secured to the side of the chain clamp.
- This set provides precise radial and angular alignment of motors, pumps & compressors and is also capable of addressing radial and angular misalignments. It comes in a case for proper organisation and protection of the components.
Frequently Asked Questions:
Q. What is shaft alignment tolerance?
A. Shaft alignment tolerance is the maximum amount of misalignment the shafts can bear before they initiate transfer of axial & radial loads to seals, bearings, gears and other affected components of a machine.
Q. What causes shaft misalignment?
A. Relative and torsional movements sometimes lead to thermal growth or expansion that results in moving one piece of equipment to another. Also, initial high torque during startup can also force shafts out of alignment.
