Product Introduction

This heavy-duty bearing housing is a core structural component of the rear axle differential, designed to securely mount the drive pinion bearings and seal assemblies. It provides a rigid, aligned interface that ensures the active bevel gear maintains precise meshing with the differential ring gear, even under extreme torque loads.

Structure & Material

• Material: High-strength cast alloy steel, selected for its exceptional rigidity, impact resistance, and ability to maintain dimensional stability under thermal stress.

• Design: A one-piece cast housing with precision-machined bores for the inner and outer drive pinion bearings, integrated seal seats, and a flange for differential carrier attachment. The housing features mounting points for the axle seal and bearing preload adjustment components.

Performance

• Precision Alignment: The precision-machined bores ensure the drive pinion bearings are perfectly aligned, maintaining optimal gear meshing and reducing wear.

• Load Support: Provides a rigid structure to handle the high radial and axial loads from the active bevel gear.

• Seal Integration: The integrated seal seats ensure proper lubricant retention and contamination protection for the differential bearings.

Durability

• Cast alloy steel construction resists deformation and fatigue under continuous heavy torque and thermal loads.

Core Function

1. Bearing Mounting: Secures and aligns the inner and outer bearings of the active bevel gear.

2. Precision Alignment: Maintains the drive pinion’s correct position for optimal meshing with the ring gear.

3. Lubrication & Contamination Protection: Integrates with seals to retain differential lubricant and block external contaminants.

Bearing Housing 810W35601-0040 for Sinotruk Sitrak – Factory Direct Supply

When your Sinotruk Sitrak heavy-duty truck demands reliable rear axle performance, every component matters — especially the bearing housing. The Bearing Housing 810W35601-0040 is engineered to precisely locate and secure the axle bearing in place, ensuring smooth load-bearing rotation under the most demanding operating conditions. At Mettlead, we supply this genuine-spec part directly from our factory in China, which means you get OEM-grade quality without the inflated middleman markup.

Whether you’re managing a fleet maintenance program or sourcing replacement parts for your workshop, this bearing housing delivers the dimensional accuracy and material strength that Sitrak trucks require. Let’s walk you through exactly what makes this part the right choice for your operation.

Key Features and Benefits of Bearing Housing 810W35601-0040

This isn’t just a chunk of metal — it’s a precision-machined component that plays a critical role in your truck’s rear axle assembly. Here’s what sets it apart:

• Precise Bearing Positioning: The housing is manufactured to tight tolerances, ensuring the axle bearing sits exactly where it should. This eliminates play and prevents premature wear caused by misalignment.
• Heavy Load Capacity: Designed specifically for Sinotruk Sitrak heavy-duty trucks, this bearing housing withstands the continuous rotational loads and shock forces that come with long-haul freight and construction site operations.
• Durable Material Construction: Cast from high-strength alloy with heat treatment processing, the housing resists deformation and fatigue cracking even under sustained thermal and mechanical stress.
• Direct OEM Replacement: Part number 810W35601-0040 matches the original equipment specification, so installation is straightforward with no modifications required.
• Extended Service Life: Thanks to precision machining and quality material selection, this bearing housing reduces maintenance frequency and keeps your trucks on the road longer.

In other words, choosing the right bearing housing protects not just the bearing itself, but the entire rear axle system — saving you costly downtime and unplanned repairs down the line.

Application Scenario: Where This Bearing Housing Works

The Bearing Housing 810W35601-0040 is specifically designed for the following application:

• Compatible Truck: Sinotruk Sitrak (汕德卡) heavy-duty truck series
• Installation Position: Rear axle assembly
• Primary Function: Locating and fixing the axle bearing in its correct position, supporting the bearing under operational loads, and ensuring stable rotational movement
• Working Conditions: High radial and axial loads, continuous rotation, exposure to road vibration and thermal cycling

If your Sitrak truck is showing signs of rear axle noise, bearing play, or uneven tire wear, a worn or damaged bearing housing could be the root cause. Replacing it with a factory-spec part restores the axle geometry and eliminates the source of the problem.

Frequently Asked Questions About Bearing Housing 810W35601-0040

What exactly does the bearing housing do in the rear axle?

The bearing housing serves as the structural seat for the axle bearing. It holds the bearing in its precise position within the rear axle assembly, absorbs radial and axial loads during operation, and ensures the bearing rotates smoothly without shifting. Without a properly functioning housing, the bearing can become misaligned, leading to accelerated wear, noise, and eventually axle failure.

How do I know if my bearing housing needs replacement?

Common signs include unusual humming or grinding noises from the rear axle area, visible cracks or wear marks on the housing surface, excessive bearing play that persists even after bearing replacement, and uneven tire wear patterns. If you’ve replaced the bearing but the problem returns quickly, the housing itself is likely the culprit.

Is this bearing housing an exact fit for my Sitrak truck?

Yes. Part number 810W35601-0040 is manufactured to match the original Sinotruk Sitrak specifications exactly. It’s a direct drop-in replacement — no machining, shimming, or modification is needed during installation.

What material is the Bearing Housing 810W35601-0040 made from?

This housing is cast from high-strength alloy steel and undergoes heat treatment to enhance its hardness and fatigue resistance. The surface receives an anti-corrosion coating to protect against moisture and road salt exposure over the part’s service life.

Can I order this bearing housing in bulk for fleet maintenance?

Absolutely. Mettlead specializes in bulk supply for fleet operators and parts distributors. We offer volume-based pricing, consistent stock availability, and can arrange scheduled shipments to match your maintenance calendar. Simply reach out with your quantity requirements for a tailored quote.

How is quality controlled during manufacturing?

Each bearing housing goes through a multi-point inspection process that includes raw material composition testing, dimensional measurement against OEM tolerances, surface finish evaluation, and final visual inspection. Parts that don’t meet specification are rejected before packaging — so what arrives at your door is guaranteed to perform.
