Set of 50/60-45-290 471 – Precision, Durable, In Stock

Hands-on look at the Set Of 50/60-45-290 471 hydraulic cylinder

Out in Hebei’s Xingtai—specifically East Village, Dongzao Village, Huanmadian Town—you’ll find an unassuming cluster of workshops that punch well above their weight. One of the better-known exports is a welded hydraulic cylinder package that, to be honest, I initially underestimated. Then I ran through the build, pressure notes, and real-world feedback. It’s solid.

What it is, in plain terms

The assembly uses a 50/60 honed/rolled tube in 20# carbon steel, a 45 mm 45# carbon-steel piston rod with hard chrome, and ear-type ends with universal bearings and 22 mm pin holes. Porting is G 3/8, and the tank’s finished in blue paint. In fact, it’s the kind of straight-ahead spec that fits agricultural tippers, compact loaders, presses, and lift tables. Many customers say it’s “plug-and-play” with European hose sets—handy if you’re retrofitting.

Quick spec sheet

Process flow and testing (how it’s built)

- Materials: 20# tube is rolled/honed; 45# rod is ground and chrome-plated. Bearings are standard metric universal type.
- Methods: CNC turning, induction eye welding, stress relief, polishing; chrome to ISO 6158; paint bake.
- Tests: Hydrostatic proof at ≈1.5× rated; leakage test to ISO 10100; rod chrome checked for thickness and adhesion; paint salt-spray on request (ISO 9227).
- Cleanliness: Assemblies flushed to fluid cleanliness ≈ ISO 4406 18/16/13 or better (real-world use may vary).
- Service life: Commonly >1–2 million cycles at moderate load, provided alignment and filtration are in spec.

Where it’s used (and why)

Agricultural tippers, silage balers, shop presses, dock lifts, and compact industrial fixtures. The G 3/8 porting plays nicely with European assemblies. And the clevis ends? They forgive a bit of misalignment, which, honestly, saves seals in the field.

Customization options

Stroke and closed length changes, alternate mounting (trunnion/flange), port orientation, low-temperature seals, plating upgrades, and even in-rod position sensing if your control system calls for it. That’s been the industry trend—more sensors, cleaner plating chemistries, and ISO 9001/14001-backed traceability. If you need that on Set Of 50/60-45-290 471, ask for the drawing pack early.

Real-world notes and a quick case

One ag customer swapped in Set Of 50/60-45-290 471 on a 3-ton tipper cart. Pressure set at 16 MPa, fluid kept at ISO 4406 17/15/12 (close enough), and alignment shims added. After a muddy spring (the worst!), seals were still dry. A maintenance lead told me, “Surprisingly forgiving on side load—just don’t push your luck.” That tracks with the universal bearing ends helping with minor misalignment.

Compliance and documentation

Common paperwork includes ISO 9001 QA scope, material certs, pressure test report (ISO 10100), and plating specs referencing ISO 6158. If you’re building to ISO 6020-2 dimensional envelopes, request the mounting drawings to confirm interface details.

Bottom line

If you need a medium-duty, metric, clevis-mounted cylinder that won’t overcomplicate your BOM, Set Of 50/60-45-290 471 is an honest, field-proven choice. Verify stroke/length against your fixture, mind your filtration, and it’ll just work.
