0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO (OEM-Spec Replacement)

When a drilling rig works at full duty, the smallest friction point can become the loudest problem. The 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO is built to be the quiet hero in that story: a compact, high-load plain bearing element designed to support rotating or oscillating movement, reduce metal-to-metal contact, and keep alignment stable under vibration, dust, and repeated shock cycles.

At 3GEN Export, we supply this part as an OEM-spec replacement for Atlas Copco / Epiroc heavy rock drilling applications, and we deliver worldwide in 5 working days. No copied manufacturer text, no recycled catalog wording—just a clear, practical, buyer-ready explanation you can publish.

What the 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO Does in Real Operation

A plain bearing’s job sounds simple: carry load and allow motion. In rock drilling equipment, that “simple” job becomes harsh work:

• Continuous vibration from the drifter/hammer cycle

• Fine abrasive dust that tries to enter every clearance

• Heat from friction plus ambient jobsite temperatures

• Intermittent shock loads and misalignment forces

The 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO helps keep rotating interfaces smooth and controlled by creating a stable sliding surface. The perforations and split-style geometry seen in the product images strongly suggest a design that supports lubrication flow and contamination management (oil distribution paths, grease migration, and debris escape), which is critical in drilling environments where lubrication is never “perfect,” only “managed.”

Key Design Traits You Can See From the Product

Even without a datasheet in hand, the physical design tells a lot:

Split / Slotted Body

A split plain bearing can be installed more easily in certain housings and can accommodate slight tolerance variations. It also helps maintain a consistent seat and reduces installation stress in tight assemblies.

Oil/Lube Holes and Ports

The multiple round perforations are not decorative. They support:

• Lubricant distribution across the sliding interface

• Grease/oil retention pockets that reduce dry starts

• Channels for flushing micro-debris away from the contact zone

Bronze-Tone Bearing Surface

The visual finish is consistent with bronze or bronze-alloy bearing materials commonly selected for sliding wear resistance, load capacity, and compatibility with steel shafts.

Why This Part Matters More Than People Think

A worn bearing rarely fails dramatically at first. It fails quietly, then expensively.

When the 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO is near end-of-life, you typically see:

• Increasing play or “looseness” in the supported component

• Irregular wear marks on the shaft or mating surface

• Heat discoloration, scoring, or polishing lines

• Vibration that appears “random” but repeats under load

• Secondary damage: seals, housings, and shafts suffering because the bearing stopped protecting them

Replacing a plain bearing on time is often the cheapest way to protect the most expensive parts in the assembly.

Technical Overview (Buyer-Friendly)

Material and Construction

While exact metallurgy can vary by production batch, the 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO is typically selected for:

• High wear resistance in sliding contact

• Good load handling under shock and vibration

• Stable performance with grease or oil lubrication

• Compatibility with steel shafts and housings

Operating Role

This part is commonly used wherever Atlas Copco / Epiroc rock drilling assemblies require:

• Support of a rotating or oscillating shaft

• A controlled sliding interface with predictable clearance

• Reduced friction under mixed lubrication conditions

Dimensional Fit

Plain bearings are dimension-sensitive. Best practice is always to confirm:

• Inner diameter (ID) vs shaft OD

• Outer diameter (OD) vs housing bore

• Length / width vs seating depth

• Any flange, lip, or locating features (if applicable in your assembly)

If you share the assembly location (or machine serial range), 3GEN Export can help double-check fit before shipping.

Applications and Compatible Atlas Copco / Epiroc Models

Public listings for this part number show it used across several Atlas Copco drilling platforms. Depending on configuration and serial range, the 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO is referenced for machines such as:

• ROC D7, ROC D9C, ROC D11

• FlexiROC T35, FlexiROC T40

• SmartROC T35

• Simba S7D

Additional part references also associate the same part number with various Atlas Copco / Epiroc drifter and rig families, including listings that mention COP-series rock drills and multiple rig models.

Because drilling fleets are often upgraded over time (and part usage can vary by build spec), the safest approach is to confirm with your parts book or serial number before purchase—even when the part number matches.

Installation Notes for Long Service Life

A plain bearing can be “new” and still fail early if installation is rushed. Here’s a field-smart approach.

Pre-Installation Checks

• Clean the housing bore completely (no old grease lumps, grit, or burrs)

• Inspect the shaft for scoring, taper wear, or out-of-round

• Verify the bearing seat is not ovalized

• Check that seals (if present) are still doing their job—seals protect bearings as much as lubrication does

Installation Best Practices

• Press-fit evenly (avoid hammering directly on the bearing surface)

• Maintain correct orientation (if the assembly requires holes aligned with lube passages)

• Use a proper driver tool that contacts the bearing’s stronger edge, not the thin mid-wall

• After installation, rotate/fit-check the mating part slowly to confirm smooth movement

Lubrication Guidance

• Use the recommended grease/oil grade for your rig environment

• Purge old grease if contamination is suspected

• Establish a routine: frequent, small lubrication intervals typically outperform rare, heavy greasing in dusty drilling conditions

Maintenance: How to Spot Wear Before It Spreads

Think of the bearing as a “sacrificial layer” designed to protect the expensive components around it. Monitor it like you would monitor a filter.

Early Warning Signs

• Slight increase in clearance (measurable play)

• Uneven contact pattern or localized polishing

• Noise that appears only under load, not at idle

• Grease turning dark quickly after service (a contamination clue)

What to Do When You See Wear

• Replace the bearing before the shaft starts wearing

• Inspect housing alignment and seal condition

• Check lubrication delivery points (blocked channels are common in dusty operations)

Practical shipping guidance for the 0500450061, 0500 4500 61 PLAIN BEARING ATLAS COPCO (based on typical plain-bearing size/material in this category):

• Estimated net weight: 0.10 – 0.30 kg (varies by exact dimensions/material batch)

If you want, tell me your preferred carrier (DHL/FedEx/UPS) and destination country, and I’ll format a realistic shipping weight suggestion (net + packing) you can use on the product page without overstating.

Frequently Asked Questions

Is 0500450061 the same as 0500 4500 61?

Yes—these are commonly shown as the same part number formatted differently. You should publish both formats on the page so customers can find it with either search style.

Is this only for Atlas Copco or also Epiroc?

Many Atlas Copco rock drilling lines were transitioned under Epiroc branding; parts are often referenced across both naming conventions. Always confirm by serial range and parts book.

What happens if I run it until it “fails”?

It often doesn’t fail suddenly—it wears, creates play, and then damages shafts/housings. Replacing the bearing early is usually cheaper than repairing the assembly.
