Product Introduction

This deep groove ball bearing is a critical component for enabling smooth, low-friction rotation in heavy-duty vehicle drivetrain systems.

• Structure & Material: Constructed from high-strength chrome bearing steel, with a precision-machined inner and outer race, and hardened steel balls separated by a cage. The design allows it to handle high radial loads and moderate axial loads.

• Performance: The deep groove design and high-quality steel construction ensure low friction, high rotational accuracy, and resistance to wear and fatigue. It is lubricated for life, requiring no maintenance under normal operating conditions.

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

3. Long-Term Reliability: The hardened steel construction and sealed design (where applicable) ensure reliable performance over long service intervals.

Customer Case Study – Rolling Bearing 6020 AZ9003326020 in Action

In early 2024, a wholesale distributor based in Lagos, Nigeria, reached out to Mettlead with a recurring challenge. Their customers — fleet operators running SINOTRUK HOWO dump trucks — were experiencing premature gearbox failures. After investigation, the root cause traced back to substandard rolling bearings sourced from unverified local suppliers.

The distributor decided to source the Rolling Bearing 6020 AZ9003326020 directly from Mettlead. We shipped an initial order of 200 units with full quality certificates and traceability documentation. Within three months, the feedback was clear: gearbox service intervals extended by approximately 40%, warranty claims dropped significantly, and the distributor’s reputation in the local market improved noticeably.

By the second quarter, this partner scaled their orders to 800 units per shipment, adding custom-branded packaging to build their own aftermarket brand identity. Today, they remain one of our consistent repeat buyers for SINOTRUK HW gearbox rolling bearings and related transmission components.

This is the type of partnership we build at Mettlead — grounded in product quality, transparent communication, and mutual growth.

Frequently Asked Questions – Rolling Bearing 6020 AZ9003326020

What is the exact fitment for Rolling Bearing 6020 AZ9003326020?

This rolling bearing is designed specifically for the SINOTRUK HW Series gearbox. It fits models including HW19710, HW19712, HW15710, and HW25712 transmissions. The bearing sits on the shaft assembly inside the gearbox housing, handling both radial and light axial loads during power transmission.

Is this Rolling Bearing 6020 the same as a standard 6020 deep groove ball bearing?

While the dimensional profile (100mm × 150mm × 24mm) follows the standard 6020 specification, the AZ9003326020 version is manufactured to SINOTRUK’s OEM tolerances and material requirements. This means tighter clearance control, specified heat treatment parameters, and quality benchmarks that generic industrial bearings may not meet. For gearbox applications under heavy-truck loads, using the OEM-specified version is always recommended.

How can I verify the quality of this bearing before placing a large order?

We encourage all new partners to start with a sample order. Each bearing ships with dimensional inspection reports, and we can provide hardness testing certificates and material composition data upon request. Additionally, you’re welcome to visit our facility in China for an on-site quality audit — we support factory inspection visits for serious wholesale partners.

What is the typical service life of Rolling Bearing 6020 AZ9003326020 in a working gearbox?

Under normal operating conditions — proper lubrication, standard load profiles, and regular maintenance — this bearing typically lasts between 150,000 to 250,000 km before requiring inspection or replacement. However, actual service life varies depending on operating environment, load severity, and maintenance practices.

Can I order this bearing with my own brand name and packaging?

Absolutely. Mettlead offers complete white-label and custom packaging services for the Rolling Bearing 6020 AZ9003326020. You provide your brand design, and we handle printing, labeling, and packaging — making it ready for direct resale in your market.

What causes premature failure of gearbox rolling bearings like the 6020?

The most common causes include contaminated or insufficient lubrication, misalignment during installation, excessive load beyond rated capacity, and using low-quality aftermarket bearings that don’t meet OEM hardness or tolerance specs. Sourcing genuine-spec bearings like AZ9003326020 from a verified supplier significantly reduces premature failure risk.
