Precision Shafts, Gears & Threaded Fittings

Shafts, gears, couplings and threaded fittings usually fail when tolerance, concentricity, material or surface finish is ignored. These examples show the types of parts EKINSUN can review from drawings or samples.

Who Gets Quotes From Us?

Common situations where maintenance teams, gearbox shops and machine builders send us a shaft, gear or fitting instead of waiting on an OEM.

// Maintenance / Reliability Engineer

"A drive shaft sheared — the OEM part is obsolete or quoted at 12 weeks"

Send us the broken or worn shaft. We reverse-engineer it from the sample (no drawing needed), re-cut the keyways, splines, tapers and threads, machine it in 4140 / 4340 / 17-4 or stainless and heat-treat to match. MOQ 1, quoted in 24 hours from photos and key dimensions.

// Gearbox / Power-Transmission Repair

"I need one replacement gear to mesh with my existing set — no part number"

Send the worn gear (or the mating gear). We count teeth, measure the module/DP, pressure angle and bore, and cut a new spur, helical, bevel or worm gear by hobbing or gear milling — often saving well over half the cost of a new gearbox or assembly.

// Machine Builder / OEM

"Small batch of custom shafts — keyways, splines and ground journals to drawing"

We machine custom shafts, spindles and pinion shafts with keyseats (broached), internal/external splines, retainer grooves, tapers and threads, then grind journals and thread-grind to tight tolerance. First article inspection, then repeat batches at tiered pricing.

// Equipment / Fluid-System Engineer

"Custom threaded fittings and couplings — non-standard threads, certs needed"

We machine custom threaded fittings, couplings, adapters and worm/worm-wheel sets in brass, bronze, 304/316L or alloy steel, to any thread standard (BSP, NPT, metric, UN). EN 10204 3.1 material certs and inspection reports supplied on request.
