2V4876 BEARING CATERPILLAR

2V-4876 BEARING CATERPILLAR

Heavy-duty bearing solution for CAT construction and mining fleets

The 2V4876 BEARING CATERPILLAR is a compact but critical component designed to keep high-load systems running smoothly in wheel loaders, construction loaders and other CAT machines. Wherever rotating motion, shock loads and continuous vibration come together, this bearing takes on the role of stabilizing the shaft, reducing friction and protecting the surrounding parts from premature wear.

On busy jobsites, even a small bearing failure can stop an entire machine. That is why fleet managers and service technicians rely on robust parts such as the 2V-4876 BEARING CATERPILLAR. When installed in the correct position and maintained with clean lubrication, it helps the drivetrain and linkage assemblies operate quietly, efficiently and with less downtime.

3GEN Export supplies this part as an OEM-level replacement and ships worldwide within 5 working days, supporting workshops, contractors and distributors who need reliable availability and fast delivery.

What the 2V4876 bearing does inside your machine

A bearing in a Caterpillar assembly has two main tasks: carry the load and guide the movement. The 2V4876 BEARING CATERPILLAR is positioned to support a rotating or oscillating shaft. Its hardened inner surface allows the shaft to move freely, while the outer surface fits tightly in the housing, holding the whole assembly in correct alignment.

When a loader is pushing into a pile of rock, or when a machine is climbing over uneven ground, the parts connected to this bearing are exposed to:

• Strong radial and axial forces

• Constant changes in direction

• Sudden impacts and shock loads

• Dust, moisture and temperature changes

The design of the 2V-4876 BEARING CATERPILLAR allows it to handle these conditions without deforming or overheating. With low internal friction, it reduces energy loss and helps the machine transfer more power from the engine to the working components.

Construction, materials and key technical features

Optimised geometry

The bearing has a cylindrical outer surface and a precisely machined inner raceway. This geometry keeps the load distributed around the full circumference, avoiding concentrated stress points that could cause cracks or early failure. The tight dimensional tolerances are matched to Caterpillar housings and shafts, so the part fits correctly without modification.

High-strength steel and heat treatment

To give the bearing its strength and long life, it is manufactured from high-quality alloy steel. Heat treatment processes increase surface hardness and improve resistance to fatigue and pitting. The result is a raceway that can withstand repeated rolling contact under heavy load for thousands of operating hours.

Surface protection

The outer and inner surfaces are finished to a smooth, corrosion-resistant state. This finish helps maintain a stable lubrication film and protects the metal from rust in humid or muddy environments. It also makes installation easier, as the bearing can be pressed into position without scoring the housing.

Weight

The approximate weight of the 2V4876 BEARING CATERPILLAR is 0.42 kg. This compact size allows it to be used in relatively tight spaces while still carrying significant loads.

Typical applications and working environments

The 2V-4876 BEARING CATERPILLAR appears in assemblies where a rotating element must stay accurately guided despite vibration and dirt. Common applications include:

• Drivetrain support points in wheel loaders

• Linkage or pivot positions in loading systems

• Powertrain components with continuous rotation

• Structural joints subject to oscillating movement

In these positions the bearing faces:

• Abrasive dust in quarries and aggregate plants

• Mud and water on construction and forestry sites

• Large temperature swings between cold mornings and hot afternoons

• Continuous start-stop cycles during loading, hauling and dumping

Because of its robust design, the part maintains its performance even when maintenance intervals are long and working conditions are severe, as is often the case in mining and earthmoving operations.

Compatible Caterpillar machines

The 2V4876 BEARING CATERPILLAR is used across several CAT machines and assemblies. It is commonly associated with the following models and series (usage may depend on specific serial numbers and configurations):

• CAT 950 wheel loader family

• CAT 966 wheel loaders

• CAT 970 and 972 series loaders

• CAT 980 production loaders

• CAT 938 loaders and similar construction loaders

• Selected drivetrain and powertrain groups in comparable CAT equipment

Service technicians should always confirm application details using the machine’s parts manual or electronic parts catalog, but this list provides a practical guide for identifying where the 2V-4876 BEARING CATERPILLAR may be required in a fleet.

Installation guidelines for long bearing life

Correct installation is essential for unlocking the full life of any bearing. When replacing or fitting the 2V4876 BEARING CATERPILLAR, technicians should follow these best practices:

1. Prepare the housing and shaft

• Clean the housing bore and shaft thoroughly to remove dirt, rust and old grease.

• Inspect for scoring, out-of-round conditions or other damage.

• Check that dimensions match the bearing specification to avoid loose or excessively tight fits.

2. Use proper tools and methods

• Press the bearing into the housing using an appropriate mandrel or installation tool that contacts only the outer race.

• Avoid hammering directly on the bearing, which can bruise the raceways or create internal stresses.

• Ensure that the part is seated squarely and fully in the bore.

3. Lubricate correctly

• Apply the lubricant recommended by the machine manufacturer.

• Fill the cavity or grease channel as specified – too little lubrication accelerates wear, too much can cause overheating at high speed.

• After assembly, rotate the shaft by hand to distribute lubricant and verify smooth movement.

4. Check alignment and clearances

• Confirm that there is no binding, roughness or unusual noise when the shaft is turned.

• Measure any specified end-play or radial clearance and compare with service limits.

• If the machine is equipped with additional bearings in the same line, ensure they are all aligned to prevent axial loading outside the design envelope.

When these steps are followed, the 2V-4876 BEARING CATERPILLAR can deliver a long operating life, reducing unplanned shutdowns and saving on repair costs.

Maintenance tips to protect your investment

After installation, regular inspection and lubrication are the keys to protecting the bearing and the associated components:

• Follow the lubrication interval from the CAT service schedule, shortening it for extremely dusty or wet environments.

• Monitor the area around the bearing for oil leaks, unusual noise, vibration or temperature rise.

• Check for misalignment or loose fasteners in the surrounding structure, as these can transfer extra load into the bearing.

• Replace seals promptly if they show damage, since contaminated lubricant is one of the main causes of early bearing failure.

By combining correct installation with disciplined maintenance, fleet managers can significantly extend the life of the 2V4876 BEARING CATERPILLAR and reduce the total cost of ownership for their machines.
