Search this category by sizeJoint and pivot elements are precision-turned connecting parts that carry the rotational, oscillating and angular motion of a mechanism. They work under load in automotive tie-rod and steering links, agricultural and construction machinery, hydraulic-pneumatic cylinder eyes, robotic arms and general machine joints. This category holds 7 families and 63 types: Rod End Pin, Ball Stud, Spherical Pin, Clevis Pin, Pivot Pin, Knurled Press-Pivot Pin and Double-Threaded Ball Pin. We machine steel, stainless steel, brass and aluminum; spherical surfaces and bearing diameters are typically held to h6/g6, mating bores to H7; ±0.01 mm is targeted on critical diameters. Production is completed in a single operation on the Goodway SW-20 Swiss-type lathe across a ⌀1–20 mm bar range. Beyond the 63 standard types we also manufacture to your technical drawing in custom sizes and thread specs. Pricing is by quote — tell us the part, material and quantity, and send your drawing for a quote.
Across 63 variants the operation mix is 30× thread turning, 4× hex flat milling, 8× axial bore, 8× taper turning, 9× knurling. Parts run 15–69 mm long; the longest, MAFA-RDP-12L at 69 mm, still finishes in a single setup.
Tolerances span 5 classes (6g, h6, h7, h8, h9) and 55 variants carry a DIN or ISO reference. The highest length-to-diameter ratio in the category belongs to MAFA-KPV-03 at L/D 6 — slender enough to need tailstock support on a conventional lathe.
Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.
Frequently Asked Questions
We turn them from bar in a single operation on the Goodway SW-20 Swiss-type lathe. The spherical head and the stud body are machined in the same setup; threaded ends (e.g. M5–M12) and any knurl or chamfer are completed in the same cycle. The sliding-headstock design keeps runout low on slender, long geometries, which is ideal for pins and studs.
Steel, stainless steel, brass and aluminum. Load-bearing joint and pivot pins are usually steel or stainless; stainless for corrosive environments; brass for conductivity, wear and decorative uses; aluminum where light weight matters. We can advise on material choice based on your application.
Bearing and spherical diameters are typically held to h6/g6, mating bores to H7; ±0.01 mm is targeted on critical diameters. On request we share a measurement/inspection report for the relevant dimensions. If your requirement is unclear, we suggest tolerances based on the part's function in your drawing.
Yes. The 63 standard types are a starting point; we manufacture to your technical drawing (DWG/PDF/STEP) in custom diameters, lengths, threads and ball-head sizes. Most joint and pivot geometries within the ⌀1–20 mm bar range are covered on the SW-20.
Pricing is by quote and depends on quantity, material, tolerance and the drawing. We have manufactured in Düzce, Turkey since 2009 and serve both domestic and export orders. Sample/first-article approval and the series-production plan are confirmed during the quote stage.
