Product Introduction

This deep groove ball bearing with a snap ring is a critical component for enabling smooth, low-friction rotation while providing secure axial positioning in heavy-duty vehicle drivetrain systems.

• Structure & Material: Constructed from high-strength chrome bearing steel, with a precision-machined inner and outer race, hardened steel balls, and a cage. It features an integrated snap ring groove on the outer race for axial retention.

• Performance: The deep groove design and high-quality steel construction ensure low friction, high rotational accuracy, and resistance to wear and fatigue. The snap ring groove provides a reliable method for axial positioning, preventing unwanted movement.

• Durability: The bearing steel and precision manufacturing ensure long service life even under high vibration and temperature fluctuations.

• Compatibility: Direct OE replacement, fully matching the dimensional, load-bearing, and retention specifications of Sinotruk heavy-duty vehicle drivetrain components.

Core Function

1. Radial Load Support: Provides low-friction support for rotating shafts, reducing wear and enabling efficient power transmission.

2. Axial Retention: The integrated snap ring groove allows for secure axial positioning, preventing the bearing from moving along the shaft.

3. Smooth Rotation: The precision-machined races and balls ensure consistent, vibration-free rotation, contributing to a smooth driving experience.

Customer Case Study – Rolling Bearing 6213N AZ9003326213 for Fleet Maintenance

Earlier this year, a fleet maintenance company based in East Africa reached out to Mettlead with a recurring problem. They managed over 120 SINOTRUK HOWO dump trucks operating in mining regions, and gearbox bearing failures were causing costly unplanned downtime. Specifically, the Rolling Bearing 6213N (AZ9003326213) inside their HW series gearbox units was wearing out faster than expected due to dust contamination and heavy load cycles.

After reviewing their requirements, our technical team recommended a bulk supply plan for the AZ9003326213 rolling bearing with customized sealed packaging to protect against storage contamination. We shipped 500 units within 12 days of order confirmation. The result? Their gearbox rebuild turnaround time dropped by 40%, and bearing-related failures decreased significantly over the following six months. Today, they reorder the Rolling Bearing 6213N AZ9003326213 from Mettlead every quarter as part of their preventive maintenance program.

This is exactly the kind of partnership we build — practical, reliable, and focused on keeping your trucks on the road.

Frequently Asked Questions – Rolling Bearing 6213N AZ9003326213

What does the “N” in 6213N mean for this gearbox bearing?

The “N” suffix indicates that the outer ring of the bearing has a snap ring groove. This feature allows a retaining snap ring to be fitted, which helps position the bearing axially inside the SINOTRUK HW gearbox housing. It simplifies assembly and ensures the bearing stays securely in place during operation.

Is the Rolling Bearing 6213N AZ9003326213 an exact replacement for the original SINOTRUK part?

Yes, absolutely. The bearing we supply is manufactured to the exact OEM dimensions and tolerances specified by SINOTRUK for the HW series gearbox. The inner diameter (65 mm), outer diameter (120 mm), and width (23 mm) all match the original part, so it installs as a direct drop-in replacement without any machining or modification.

What material is used in this 6213N rolling bearing?

The bearing is made from high-carbon chrome steel (GCr15), which is the industry-standard material for precision rolling bearings. This material offers excellent hardness, fatigue resistance, and dimensional stability — all essential for long service life inside a heavy-duty gearbox.

How long does the Rolling Bearing 6213N AZ9003326213 typically last in a SINOTRUK HW gearbox?

Under normal operating conditions with proper lubrication and maintenance, this bearing typically lasts between 150,000 and 300,000 kilometers. However, service life varies depending on load conditions, operating temperature, contamination levels, and maintenance practices. For mining or heavy-haul applications, more frequent inspection intervals are recommended.

Can I order this bearing in large quantities with custom packaging?

Yes. Mettlead supports bulk orders with white-label or custom-branded packaging. Whether you need neutral boxes for aftermarket distribution or fully branded packaging with your logo and part number, we handle it. Just let us know your requirements when you send your inquiry.
