8G-0010 BEARING CATERPILLAR (8G0010) – Sleeve Bearing / Bushing

When your undercarriage and chassis assemblies work every day in dust, mud, rock, and extreme heat, the smallest wear surface can decide the uptime of the entire machine. 8G-0010 BEARING CATERPILLAR is a precision sleeve bearing (bushing) designed to support rotating or oscillating movement while protecting higher-cost components from direct metal-to-metal wear. This is the kind of part that quietly absorbs load, maintains alignment, and helps moving joints stay stable, until it wears out. Then clearances grow, vibration increases, seals start to suffer, and the repair becomes bigger than it needed to be.

At 3GEN Export, we supply 8G-0010 BEARING CATERPILLAR as an OEM supplier alternative for fleet owners, workshops, and international buyers who want reliable fitment and fast logistics. We deliver worldwide in 5 working days, helping you keep maintenance plans on schedule and machines earning instead of waiting.

What 8G-0010 BEARING CATERPILLAR Does in Real Work Conditions

A sleeve bearing is a simple-looking component, but its job is demanding. 8G-0010 BEARING CATERPILLAR sits between a shaft/pin and a housing, creating a controlled bearing surface. Instead of expensive structural parts wearing down, the bushing becomes the sacrificial interface, easy to replace, cost-effective, and critical for maintaining correct geometry.

In heavy equipment, bushings like 8G-0010 BEARING CATERPILLAR are commonly used anywhere there is:

• High radial load (weight and shock transferred through joints)

• Repeated oscillation (back-and-forth movement)

• Dirt contamination risk (harsh environments)

• The need to protect pins/shafts and bores from scoring

Catalog listings show 8G-0010 BEARING CATERPILLAR used in undercarriage-related groups such as idler/track roller frame assemblies on certain track loader configurations.

Identifying the Part from the Images

Your photos show a robust, machined, cylindrical ring-style bearing with a smooth outer surface and a finished inner bore. This geometry matches what you expect from 8G-0010 BEARING CATERPILLAR as a sleeve-type bearing: consistent wall thickness, controlled inside diameter for correct running clearance, and an outer diameter designed for a firm press-fit into its housing.

This shape supports stable alignment under load and helps distribute contact pressure across a wider surface, especially important in tracked machines where impacts and vibration are constant.

Technical Specifications of 8G-0010 BEARING CATERPILLAR

Below are the dimensional and material specifications commonly listed for 8G-0010 BEARING CATERPILLAR:

Key Dimensions

• Outer Diameter: 51 mm

• Inner Diameter: 38 mm

• Length (Width): 28 mm

Material

• Hardened steel

These dimensions matter because even a small mismatch can lead to improper press-fit, spinning in the bore, uneven wear, heat buildup, and early failure. With 8G-0010 BEARING CATERPILLAR, correct OD/ID/length ensures load is carried where it should be and lubrication (if used in the assembly) behaves predictably.

Estimated Weight (KG)

Caterpillar part listings don’t always publish net mass for every small wear component. Based on the published dimensions (OD 51 mm, ID 38 mm, length 28 mm) and a typical steel density, the estimated weight of 8G-0010 BEARING CATERPILLAR is:

• Approx. 0.20 kg

This is an engineering estimate for planning and shipping calculations. Actual packed weight can vary depending on protective packaging.

Compatible Caterpillar Models Using 8G-0010 BEARING CATERPILLAR

The following machine models are commonly listed as compatible with 8G-0010 BEARING CATERPILLAR:

• Caterpillar 508

• Caterpillar 973

• Caterpillar 973C

Additional parts-catalog references also show 8G-0010 BEARING CATERPILLAR appearing in undercarriage/idler-related group diagrams for 973 track loader configurations.

Because compatibility can vary by arrangement number, serial-number range, and undercarriage configuration, the safest practice is to match:

• Part number (8G-0010 / 8G0010)

• Assembly group where it’s installed (idler/roller frame group, etc.)

• Machine serial number or arrangement code

If you share the machine model + serial prefix (e.g., “973C XXY”), I can format a tighter compatibility section for your product page without inflating keyword density.

Why Correct Fitment Matters for 8G-0010 BEARING CATERPILLAR

A sleeve bearing is only “simple” when it’s correctly installed and correctly matched. The wrong tolerance or surface finish can create problems that look like bigger failures:

1) Preventing Bore Damage

If the outer diameter is not correct, the bearing can rotate inside the housing. That “spinning bushing” effect quickly enlarges the bore and turns a straightforward service job into a housing repair.

2) Protecting Pins/Shafts

The inner surface of 8G-0010 BEARING CATERPILLAR is the intended wear interface. When it’s correct, it protects higher-cost shafts, pins, or spindles from scoring.

3) Controlling Vibration and Alignment

Wear clearance affects alignment. Excess clearance can introduce vibration, noise, and uneven loading, especially noticeable in undercarriage components under constant track tension and shock.

4) Supporting Seal Life

In many assemblies, seals depend on stable alignment. A worn bearing can cause seal lips to run off-center, increasing contamination ingress and accelerating the entire wear cycle.

Where 8G-0010 BEARING CATERPILLAR Is Commonly Used

While exact placement depends on the machine arrangement, catalogs indicate 8G-0010 BEARING CATERPILLARappears within undercarriage component groups such as idler-related assemblies on track loaders.

In practical terms, that means it may be part of systems that see:

• Constant shock loads from rough ground

• Abrasive contamination (sand, gravel, rock dust)

• Water exposure and washdown

• High duty cycles where lubrication intervals are tested

This is why selecting a correctly specified 8G-0010 BEARING CATERPILLAR matters: undercarriage wear components fail faster when clearances drift or hardness is inconsistent.

Installation Guidance for 8G-0010 BEARING CATERPILLAR

Below is a field-friendly approach used in professional workshops. Always follow your machine’s service manual and safety procedures.

Preparation

• Clean the housing bore thoroughly (remove rust, old adhesive residue, and debris)

• Inspect the bore for ovality, scoring, or fretting

• Check the mating shaft/pin for wear steps or heat discoloration

• Verify you are installing 8G-0010 BEARING CATERPILLAR and not a visually similar bushing

Press-Fit Best Practices

• Use a proper press tool that contacts the bearing evenly

• Press straight, avoid cocking the bearing into the bore

• Do not hammer directly on the bearing surface (this can deform edges and change clearances)

After Installation Checks

• Confirm the bearing sits square and flush to the specified depth

• Verify the shaft/pin slides or rotates as expected (depending on assembly)

• If lubrication is present in the design, confirm passages are clear and grease flow is normal

A well-installed 8G-0010 BEARING CATERPILLAR should feel “tight but correct”, no binding, no looseness, no rough spots.

Maintenance Tips to Extend Service Life

To keep 8G-0010 BEARING CATERPILLAR performing longer in harsh conditions:

• Maintain lubrication intervals (if the assembly is grease-serviced)

• Watch for early symptoms: squeal, vibration, uneven track behavior, or heat around joints

• Replace bushings before they destroy pins/shafts and housings

• Keep contamination out: seals and caps matter more than people think

In fleet operations, replacing a wear bearing early often costs less than the downtime and secondary damage caused by pushing it too far.
