1. Automotive Cylinder Block Honing Control
Used by engine rebuilders to measure the inner diameter of cylinder bores after machining. The 100–160 mm range perfectly accommodates standard passenger car and light truck engine blocks. Technicians can measure along different depths of the cylinder to identify taper and roundness errors.
Problem SolvedEnsures pistons fit with optimal clearance, preventing engine blow-by or piston seizure by detecting minute taper or ovality errors down to 0.5 µm.

2. Hydraulic Cylinder Seal Interface Inspection
Manufacturers of industrial hydraulic actuators utilize this bore gauge to verify the internal barrel diameter matches design tolerances. This ensures the elastomeric piston seals seat correctly under high operating pressures.
Problem SolvedPrevents internal fluid bypass and pressure loss in high-pressure hydraulic cylinders by ensuring the inner diameter stays within a 2 µm tolerance band.

3. Heavy Machinery Bearing Journal Fitting
In gearboxes and large electric motor housings, bearing seats must be machined to a precise interference fit. The 511-704 is used to measure the machined ID before pressing in bearings with outer diameters between 100 mm and 160 mm.
Problem SolvedAvoids bearing spin or housing damage by ensuring bearing housing bore dimensions are within specified ISO tolerance limits.
