The AZ4071410052 Spacer Ring is a precision‑engineered component designed to maintain accurate axial positioning and load distribution in heavy‑truck driveline assemblies. Manufactured from high‑strength alloy steel with a corrosion‑resistant finish, this spacer ring ensures consistent bearing preload, reduces wear, and extends the service life of transmissions and axle systems. As a critical part of genuine Howo/Sitrak truck parts, the AZ4071410052 is produced to exact OEM specifications, guaranteeing a perfect fit and superior performance in HOWO, SITRAK, and SHACMAN heavy‑duty trucks. Whether you are rebuilding a transmission, overhauling a differential, or replacing worn components during routine maintenance, this spacer ring delivers the precision, strength, and reliability required to maintain gear alignment, reduce backlash, and prevent premature bearing failure, minimizing downtime and operational costs.
The AZ4071410052 is not a simple shim; it is a precision‑machined spacer ring that provides accurate axial spacing and load distribution in critical driveline assemblies. Manufactured from high‑grade alloy steel with a uniform hardness and microstructure, this spacer ring offers exceptional resistance to deformation under high clamping loads and dynamic forces. The surfaces are precision‑ground to a fine finish, ensuring parallel faces that distribute clamping pressure evenly across the bearing or gear face. The inner and outer diameters are machined to exacting tolerances, providing a precise fit that eliminates excessive clearance and reduces the risk of component movement.
The spacer ring’s geometry is optimized to accommodate thermal expansion and contraction, maintaining consistent preload across a wide temperature range. Its design incorporates chamfered edges to facilitate installation and reduce stress concentration. Every AZ4071410052 is inspected for dimensional accuracy, including thickness, parallelism, and surface finish, guaranteeing that it meets the strictest OEM standards. This attention to detail ensures that the spacer ring performs flawlessly in demanding applications, from heavy‑haul transmissions to off‑road axle assemblies.
High‑Strength Alloy – The AZ4071410052 is forged from high‑grade alloy steel, providing exceptional strength and resistance to plastic deformation under load.
Precision Ground Faces – The parallel ground faces ensure uniform load distribution, preventing stress concentration and minimizing wear on bearings and gears.
Corrosion Resistance – The durable surface coating provides superior protection against rust and chemical attack, ensuring long‑term reliability.
Thermal Stability – The material maintains its dimensional stability from cold starts to full operating heat, preserving critical clearances.
The AZ4071410052 spacer ring is dimensionally identical to the original equipment part used in a wide range of HOWO, SITRAK, and SHACMAN transmissions, axle housings, and differentials. It is specifically designed for applications that require a spacer ring with an inner diameter of 65 mm, an outer diameter of 85 mm, and a thickness of 6 mm, matching the OEM specifications for many heavy‑duty driveline components. The ring’s precise dimensions ensure a drop‑in replacement that requires no modification, reducing installation time and eliminating the risk of fitment errors.
By choosing this genuine OEM spacer ring, you avoid the risks associated with aftermarket alternatives that may have incorrect thickness, poor parallelism, or inadequate material hardness, which can lead to improper bearing preload, accelerated gear wear, and premature driveline failure. The AZ4071410052 has been validated through extensive testing in real‑world fleet operations, confirming its ability to maintain correct spacing and load distribution over hundreds of thousands of kilometers, even under high‑torque and high‑speed conditions.
Proper installation of the AZ4071410052 is essential to achieve the correct bearing preload and to avoid damaging the ring or the mating components. Begin by thoroughly cleaning the shaft and the housing bore to remove all debris, old sealant, and corrosion. Inspect the spacer ring for any nicks, burrs, or deformation; if any damage is found, replace it. Apply a thin, even layer of clean oil or assembly lubricant to the inner and outer surfaces to facilitate installation and prevent galling.
Position the spacer ring onto the shaft or into the bore, ensuring it is squarely seated against the shoulder or bearing face. When assembling the components, tighten the retaining nut or housing bolts to the manufacturer’s specified torque using a calibrated torque wrench. After assembly, check the bearing preload or gear backlash according to the service manual to confirm that the spacer ring provides the correct spacing. Regular inspection of the AZ4071410052 during routine maintenance is recommended—look for signs of wear, scoring, or deformation. With proper installation, this spacer ring will provide reliable, long‑lasting performance.
Each AZ4071410052 spacer ring is manufactured in an ISO 9001‑certified facility, ensuring the highest levels of quality and consistency. The raw steel is sourced from approved mills and tested for chemical composition and mechanical properties. The ring is machined on precision CNC lathes and grinders, with critical dimensions verified using air gauges and coordinate measuring machines. After machining, each ring is inspected for thickness, parallelism, surface finish, and hardness to confirm it meets the specified tolerances.
Random samples from each batch are subjected to accelerated wear testing and press‑fit force testing to verify that the ring meets the design criteria. A corrosion resistance test is also performed to validate the protective coating. This comprehensive quality regimen guarantees that every AZ4071410052 delivers the same reliable performance as the original OEM component, giving you full confidence in your driveline repair.
Fleet maintenance teams and driveline specialists have come to trust the AZ4071410052 because it consistently provides the correct spacing and load distribution required for reliable driveline operation. The ring’s precise thickness and parallelism eliminate the guesswork associated with selecting aftermarket shims, reducing assembly time and ensuring consistent results. Many workshops report a significant reduction in bearing and gear failures after switching to this genuine OEM spacer ring.
Moreover, the AZ4071410052 is supplied in protective packaging to prevent damage during storage and handling. Its clear OEM number and application data simplify parts identification. When you choose this spacer ring, you are selecting a component that has been engineered and tested to the highest standards, offering the perfect balance of strength, precision, and value.
In summary, the AZ4071410052 Spacer Ring is a precision‑engineered component that ensures accurate axial positioning and load distribution in HOWO, SITRAK, and SHACMAN driveline assemblies. Its high‑strength alloy construction, exact OEM fitment, and rigorous quality control guarantee consistent performance and long service life.
