Product Introduction

This circlip is a critical fastener for the clutch actuation system, ensuring the release bearing remains securely attached to the clutch fork during operation.

• Structure & Material: Manufactured from high-strength spring steel, with a U-shaped design and a rounded loop for flexibility. The steel is hardened for high tensile strength and corrosion resistance.

• Precision Fit: Engineered to match the profile of the release bearing and clutch fork, providing a secure snap-fit that resists vibration and disengagement.

• Durability: The spring steel construction maintains its retaining force even under high vibration and temperature fluctuations, ensuring long-term reliability.

• Compatibility: Direct OE replacement, fully matching the interface and retention specifications of the HW19710 transmission clutch system.

Core Function

1. Secure Retention: Clips the release bearing to the clutch fork, preventing separation during clutch actuation and gear shifts.

2. Vibration Resistance: Maintains a tight fit under high vibration conditions, preventing component loosening and potential mechanical failure.

3. Easy Installation: The spring-loaded design allows for quick and secure assembly, requiring only simple tools for installation and removal.

Features and Benefits of Right Circlip-Release Bearing AZ2214260015

This circlip is far more than a simple retaining ring. It plays a vital role in holding the release bearing securely within the SINOTRUK HW series gearbox housing. Without a properly functioning right circlip, the release bearing can shift out of alignment, leading to premature wear, gear engagement issues, and costly downtime.

Technical Specifications

The following table outlines the key parameters for the Right Circlip-Release Bearing AZ2214260015. These specifications align with SINOTRUK OEM standards for the HW series gearbox.

Application Scenario

The Right Circlip-Release Bearing AZ2214260015 is specifically designed for the clutch release mechanism within the SINOTRUK HW series gearbox. Here is where it fits and why it matters:

Compatible Vehicles and Gearboxes

• SINOTRUK HOWO A7 / T7H / T5G heavy-duty trucks equipped with HW series transmissions
• SITRAK C7H / C5H models running HW15710 and HW19710 gearboxes
• SINOTRUK HW Series Manual Transmissions: HW15710, HW19710, HW19712, and related variants

During clutch engagement and disengagement cycles, the release bearing slides along a guide sleeve. The right circlip (AZ2214260015) acts as a retaining element that prevents the bearing from dislodging laterally. In heavy-duty transport applications — think long-haul logistics, mining haul roads, and construction site operations — this part endures thousands of clutch cycles daily. A worn or missing circlip can result in bearing misalignment, abnormal clutch noise, incomplete disengagement, and ultimately gearbox failure.

That is exactly why fleet maintenance teams and parts distributors keep this item in stock as a preventive maintenance essential.

Customer Case Study

In early 2024, a truck parts distributor based in East Africa reached out to Mettlead looking for a reliable source for SINOTRUK HW series gearbox parts — particularly the Right Circlip-Release Bearing AZ2214260015. Their previous supplier had been delivering inconsistent quality, resulting in customer complaints about premature circlip failure and release bearing misalignment in SINOTRUK HOWO fleets.

After receiving samples and verifying dimensional accuracy against OEM specifications, they placed an initial order of 2,000 pieces. Our quality control team conducted 100% dimensional inspection and hardness testing for that batch. The result? Zero returns over six months of distribution, and their end-user workshops reported noticeably better fitment compared to previous supplies.

Today, this distributor orders the AZ2214260015 right circlip-release bearing from us on a monthly basis, along with a growing list of complementary SINOTRUK HW series gearbox components. They benefit from consolidated shipping, consistent quality, and pricing that keeps their margins healthy in a competitive aftermarket.

Frequently Asked Questions

What exactly does the Right Circlip-Release Bearing AZ2214260015 do in the gearbox?

This circlip serves as a retaining clip that holds the release bearing in its correct axial position within the SINOTRUK HW series gearbox clutch housing. It prevents lateral movement of the bearing during clutch engagement and disengagement, ensuring smooth, consistent shifting performance.

Which SINOTRUK gearbox models does AZ2214260015 fit?

The AZ2214260015 right circlip-release bearing is designed for SINOTRUK HW series transmissions, including the HW15710, HW19710, and HW19712 gearbox variants commonly found in HOWO A7, T7H, T5G, and SITRAK C7H/C5H trucks.

What material is this circlip made from, and how durable is it?

It is manufactured from high-carbon spring steel (typically 65Mn grade) with a phosphate anti-corrosion coating. The hardness ranges from HRC 44 to 51, which provides excellent elasticity and fatigue resistance — critical properties for a component that endures thousands of compression cycles over its service life.

How can I tell if the right circlip-release bearing needs replacement?

Common signs include unusual rattling noises from the clutch housing, difficulty in gear disengagement, visible deformation or cracking of the existing circlip during gearbox inspection, or the release bearing sitting off-center. Experienced mechanics typically replace this circlip whenever the release bearing itself is serviced.

Is AZ2214260015 an OEM-equivalent part?

Yes. The Right Circlip-Release Bearing AZ2214260015 supplied by Mettlead is manufactured to match SINOTRUK OEM dimensional and material specifications. Every production batch is verified through hardness testing and precision measurement to ensure direct interchangeability with the original factory part.
