SANY Hydraulic Cylinder Seal Kit for SANY STC250

Hydraulic parts

SANY Hydraulic Cylinder Seal Kit

Seal kit matching for SANY boom, arm, bucket and outrigger cylinders. Seal kits are identified by the cylinder, not by the machine: bore diameter, rod diameter and the seal groove arrangement decide the kit, and a single excavator carries boom, arm and bucket cylinders in three different sizes, while a truck crane adds outrigger and telescoping cylinders again different. This listing spans a 21.9 t excavator, a 35 to 38.1 t excavator and a 25 t class truck crane, which have nothing in common at cylinder level. Measure the rod diameter and the bore and send those with the machine serial number. Two things worth knowing: a cylinder that has been resealed twice and still leaks usually has a scored rod or a worn gland bore, and no seal kit will fix that; and it is better to buy the kit for the cylinder you are opening than a set for the machine, because a cylinder that is not leaking is best left closed.

SANY Crane Outrigger Cylinder Parts

Cylinder components and seals for SANY truck crane outrigger systems. Outriggers are a structural safety system and the parts scale with the crane: the STC250 sits at 32.1 to 33.1 t operating weight on a 6.4 by 5.35 m outrigger span with 7 t of counterweight, while the STC500 hybrid builds carry 8.5 to 11 t of counterweight on spans up to 8.0 by 6.42 m. Nothing interchanges across the range, and the suffix matters even within one model — the STC250C5-1 and the STC250C5-8 already differ from each other in outrigger span. Outrigger cylinders carry load-holding valves and those must be replaced like for like: substituting a valve with a different cracking pressure on a load-bearing circuit is not a saving worth making. Send both the chassis nameplate and the superstructure serial number, since crane parts are documented in two separate books.

How STC250 Differs From the Rest of the Range

  • The C5-8 is a measurable step up from the C5-1, not just a badge change: 9 kW more power at a lower rated speed, a full second off the boom extend cycle (70 s against 80 s), a faster winch and a wider outrigger span. Hydraulic pump, valve and winch parts are the ones most likely to differ between the two — quote by the full suffix.
  • Rated lifting capacity, load moment and maximum lift height are deliberately not listed: no source publishes them for this model. The figure shown as "maximum capacity" on Chinese equipment listings is a category band, not a rated value, and load-bearing parts must never be selected from a guessed rating.
  • Truck crane part numbers are split between chassis and superstructure, which are documented in separate parts books — send both the chassis nameplate and the superstructure serial number when requesting a quote.

Compiled from a Chinese used-equipment specification database. The engine model is not recorded for truck cranes in that source, so it is omitted rather than guessed. Published figures for the C5-8 Pro and the C5-8 plug-in build are identical, which is unlikely to be correct — confirm the exact build against the machine nameplate before ordering.
