Component identification library

What to look for, what to measure and what a replacement must match — for the components engineers most often need to identify.

Mechanical

How to identify a rolling-element or plain bearing from its markings, dimensions and construction.

Identify O-rings, lip seals and mechanical seals by dimensions, profile and material.

Identify jaw, gear, disc and grid couplings from geometry, bore sizes and element type.

Identify gear reducers from the name plate, ratio, mounting and shaft arrangement.

Identify electromechanical and solid-state relays from coil ratings, pin layout and housing.

Identify motor-control contactors by frame size, coil voltage, AC-3 rating and auxiliary contacts.

Identify AC and DC motors from the rating plate, frame size and mounting.

Identify electrical connectors from pin count, pitch, keying and locking mechanism.

Identify fuses and breakers from current rating, curve, breaking capacity and format.

Identify proximity, photoelectric, pressure and temperature sensors from body form, cable and markings.

Identify industrial and hydraulic/pneumatic valves from body markings, ports and actuators.

Identify centrifugal, gear and diaphragm pumps from the name plate, casing and connections.
