Design:

The Sipma Baler Length Adjustment Sleeve 17x26x0.9 with part numbers 522308117, 202308011700 and 2023-080-117 is a core spacing positioning, clearance compensation and transmission auxiliary fastening component specially customized for the Sipma Z224 series square balers. Adopting thin-wall high-precision bushing integrated structural design optimized exclusively for the baler’s knotter transmission and roller assembly clearance system, it acts as a critical foundational functional part in the equipment’s transmission component spacing calibration, axial clearance compensation, assembly preload adjustment, linkage travel limitation and cyclic straw baling workflow operation process. This engineered thin-wall integral adjustment sleeve structure delivers outstanding axial spacing control and radial buffer positioning performance, effectively solving common failures of ordinary adjustment sleeve accessories including assembly gap deviation, transmission axial play, linkage component travel dislocation, surface extrusion deformation and fastening clearance failure after long-term high-speed cyclic rotary and reciprocating operation. Manufactured with high-density high-strength cold-rolled alloy steel materials and one-piece stamping plus precision edge trimming craftsmanship, the product undergoes strict surface passivation, oil immersion anti-rust, acid and alkali anti-corrosion and friction wear-resistant treatment. It features superior structural toughness, compression anti-deformation performance and extreme farm environment adaptability, fully adapting to harsh field working scenarios with mechanical alternating extrusion load, dust and straw debris erosion, high-speed continuous reciprocating linkage movement and frequent equipment start-stop impact. It maintains long-term stable clearance control and spacing buffering performance, ensures standardized linear travel and coaxial linkage operation of the knotter shaft, feeding roller assembly and bundling executive components, calibrates the overall operating stroke of the baler’s core transmission and knotting system, and perfectly matches the original assembly, clearance control and transmission system design of the Sipma Z224 Baler.

Dimensions:

All core dimensional parameters, including 17mm inner diameter, 26mm outer diameter, 0.9mm wall thickness, overall sleeve axial length, end face flatness tolerance, radial roundness tolerance, assembly interference fit datum and peripheral chamfer specification of this replacement length adjustment sleeve strictly comply with international mechanical precision standards and original factory OEM Sipma Z224 specifications, with core matching and stamping machining errors controlled within ±0.025mm. It achieves 1:1 full original equipment compatibility with the Sipma Z224 square baler, precisely fitting all reserved bushing mounting grooves, axial spacing assembly cavities, transmission shaft matching gaps and component locking datum surfaces of the host machine. The product supports direct plug-and-play press-fit and bolt auxiliary locking installation without secondary cutting, grinding, shimming or dimensional modification. Standardized thin-wall wall thickness uniformity and high-precision end face assembly datum ensure stable gap compensation and buffer limiting performance of the adjustment sleeve during continuous large-batch straw and hay baling work; accurate overall dimension and datum calibration realize flush, interference-matched and gap-standard assembly, avoiding transmission axial play, linkage stroke offset, adjacent mechanical component friction jamming and sleeve extrusion displacement during long-term uninterrupted high-speed cyclic operation. Its full set of dimensional and assembly datum parameters are completely consistent with original factory standard parts, perfectly adapting to the Z224 baler’s transmission operating speed, assembly preload pressure and periodic bundling linkage stroke rhythm, and retaining the long-term clearance calibration accuracy of the baler’s knotter and feeding transmission system.

Performance:

This heavy-duty field-grade length adjustment sleeve is professionally developed to adapt to the Z224 baler transmission system’s continuous high-frequency reciprocating linkage load, alternating radial and axial extrusion pressure, frequent start-stop vibration impact and all-day long-duration high-load field baling operation. Optimized with exclusive high-toughness anti-fatigue cold-rolled alloy steel formula and local edge stress dispersion reinforcement technology, it boasts prominent compression resistance, radial shear resistance, vibration fatigue resistance, friction wear durability and impact deformation resistance. During continuous straw, hay and forage baling operation with cyclic mechanical linkage and extrusion load, the component keeps stable spacing calibration capacity and consistent clearance compensation effect without thin-wall bulging, end face collapse, inner and outer surface abrasion, crack propagation and assembly displacement loosening. Its overall service life is 45% longer than ordinary universal adjustment sleeve replacement accessories on the agricultural machinery spare parts market. Authoritative cyclic vibration and heavy-load extrusion bench tests verify that its ultimate compression bearing capacity and structural mechanical stability far exceed the daily working load and full-load operation frequency of the Sipma Z224 baler’s matching adjustment assembly. It thoroughly eliminates frequent typical equipment malfunctions caused by inferior sleeve fatigue deformation and clearance calibration deviation, including irregular bundling knot formation, transmission linkage jitter, feeding roller uneven operation, knotter travel overrun, baler intermittent shutdown and unqualified density of finished square bales, supporting long-term non-stop high-efficiency field baling operation of the Sipma Z224 square baler.
