Selection references for bearings, sensors, drives, relays, valves, pumps, transmitters and controls — what each parameter means and which ones decide the part.
What the markings on an industrial component actually tell you: date codes and shelf life, serial numbers for calibrated and safety-related items, a six-shot photograph protocol, and what to do when the marking has worn away.
Two different numbers that look identical, and why confusing them causes most wrong-part deliveries. What an MPN encodes, why a supplier catalogue number is only meaningful to that supplier, the fields every purchase order line needs, and how to keep a cross-reference record alive.
When reverse engineering is the right answer for an obsolete spare part and when it is a liability. The information package a workshop needs, why measuring a worn part gives the wrong nominal, and how to agree acceptance testing before the first item is made.
An industrial part number is a compressed specification. How the prefix, base code and suffix string are built, which characters change behaviour, how to identify a part from measurements alone, and how to write an enquiry that gets answered.
A robotic arm is defined less by its appearance than by three numbers: payload, reach and repeatability. Everything else — the number of axes, the mounting, the controller — follows from the task the arm has to perform. Configurations Articulated — the general-purpose 6-axis arrangement; the widest range of applications. Read more
Industrial robots perform the tasks that are dangerous, repetitive or beyond human consistency. Their value is not only labour substitution: in welding, painting and assembly they deliver repeatability that directly determines product quality. Common configurations Articulated (6-axis) — the general-purpose workhorse for welding, handling and assembly. SCARA — fast horizontal Read more
A touch-screen HMI (human-machine interface) replaces hard-wired buttons and lamps with a configurable display. Selecting the right one is about matching the environment, the controller and the software — not just the screen size. Types Basic text/graphic panels — small, low-cost, for simple machine control. Touch panels with PLC connectivity Read more
An electromagnetic (magnetic) flowmeter measures the flow of a conductive liquid using Faraday’s law of electromagnetic induction: a conductor moving through a magnetic field generates a voltage proportional to its velocity. Principle Coils around the pipe generate a magnetic field; electrodes in contact with the liquid pick up the induced Read more
The aerospace supply chain spans everything from raw material and fasteners to complete avionics and hydraulic systems. What separates it from general industrial sourcing is not the parts themselves but the traceability and documentation that must accompany them. Component categories Airframe and structure — fuselage frames, stringers, ribs, skins, fittings Read more
Bearing units and linear motion components are the parts that quietly determine whether a machine runs smoothly or vibrates itself apart. They are also among the most cross-referenceable items in the plant, which makes them easy to source — provided the dimensional and sealing details are right. Bearing units Flanged Read more
