3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO
If you run an Atlas Copco/Epiroc Boomer-class underground drill, sealing performance isn’t a “nice to have” detail, it’s what keeps hydraulic power stable, keeps contamination out, and keeps expensive cylinder surfaces from turning into scrap. The 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO is a purpose-built seal ring / guide ring–type sealing element used in Boomer-related hydraulic assemblies (commonly in cylinder sealing stacks where low friction + tight control matter).
In practical terms, 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO helps your machine hold pressure, move smoothly, and resist dust/mud ingress that’s typical in drifting, tunneling, and production drilling, where every cycle is hard work and downtime is expensive.
What the 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO does
A seal ring in a Boomer environment usually has three jobs:
Seal hydraulic pressure so the cylinder can generate force consistently
Control leakage (internal bypass + external seepage) to preserve efficiency
Protect metal surfaces (rod/tube) by stabilizing alignment and reducing scoring
The design you shared (ring form with banded outer surface) is consistent with a wear/guide ring + sealing ring stylecomponent used inside hydraulic cylinder packs, especially where side-loads and vibration are common on booms and feeds.
Where this type of seal ring is typically used
Depending on the Boomer/Simba configuration, 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCOmay appear in assemblies such as:
Boom cylinders (lift/tilt/extension, depending on rig)
Feed/guide or telescopic cylinder applications on certain rigs
Linkage cylinders where smooth movement and anti-stick-slip behavior matter
A parts listing for Boomer L1C references this part number as a seal in the bill of materials, indicating its role inside a sealing set rather than being a simple external rubber ring.
Why this seal ring matters in underground drilling
In underground drilling, seals fail faster because conditions are tougher than standard mobile hydraulics:
Fine abrasive dust migrates everywhere
Pressure spikes happen during percussion/boom movement and sudden stops
Side loads increase when the boom works off-center or at full reach
Heat cycling accelerates seal hardening and extrusion over time
When 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO is fresh and correctly installed, you normally see:
More stable feed/boom response
Less “spongy” cylinder feel
Reduced oil film/weep around cylinder areas
Better long-term protection of cylinder bore and rod finish
When it’s worn, you’ll often notice slower response, drift, chatter, or hydraulic oil contamination that gets worse each week.
Design and material logic behind the 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO
Most Boomer-class cylinder seal rings are engineered around low friction + high wear resistance + extrusion control. While exact compound varies by supplier and application, seal rings in this family are commonly built from:
Polyurethane (PU) or engineered polymer for wear resistance
Composite fabric-reinforced polymer for stability under side load
PTFE-based sliding layers (in some designs) to reduce stick-slip
The banded appearance in your images is typical of reinforced wear/guide style elements, where the material is designed to carry load, stay dimensionally stable, and protect metal-on-metal contact.
How that translates to performance
A well-made 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO is designed to:
Keep friction controlled so the boom moves smoothly at low speed
Resist edge wear from vibration and micro-misalignment
Prevent scoring on rods/bushings by maintaining guidance
Reduce the chance of seal “roll” or twisting during pressure reversals
Key benefits (what buyers actually care about)
1) Pressure stability and predictable motion
Boom control is your productivity. When 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO is doing its job, the cylinder seals efficiently, which means:
Faster response
Less lag under load
Less drift when holding position
Less energy waste (and less heat)
2) Longer component life
This is where seal rings pay for themselves. A worn ring can cause:
Rod scoring
Bore wear
Metal debris in oil
Premature pump/valve wear
Keeping the 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO in good condition protects the entire hydraulic loop.
3) Better contamination resistance
Underground dust is brutal. Good sealing reduces:
Ingress of abrasive particles
Oil contamination
Accelerated wear on adjacent seals and bushings
Technical details (practical specs you can list on your product page)
Because exact dimensions and compound can vary by equipment configuration and revision, the most useful “website-ready” technical spec section is one that states function + material class + operating realities, while prompting customers to confirm by part number.

Installation guide for 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO
Below is a clean, field-realistic installation section you can publish (and it also helps your conversions because it signals expertise).
Tools and prep
Clean bench and lint-free cloth
Plastic pick tools (avoid metal that can nick sealing edges)
Calipers (to verify groove and ring condition if needed)
Correct hydraulic assembly lubricant (compatible with seal material)
Torque tools for cylinder reassembly
Step-by-step installation (best practice)
Confirm the part number on your job card and packaging: 3128209301 / 3128 2093 01.
Inspect the groove and mating surfaces for burrs, scoring, or embedded debris.
Clean and dry the area, no grit, no metal shavings, no cloth fibers.
Lubricate lightly with a compatible lubricant (too much grease can trap abrasives later).
Install without twisting. If the ring is a guide/wear style, keep it seated evenly along the groove.
Check free movement before final assembly: the component should not pinch or bind.
Reassemble and pressure-test gradually. Start with slow cycles, then normal duty.
Common mistakes to avoid
Forcing the ring over sharp edges (creates micro-tears that fail early)
Installing dry (increases startup friction and heat)
Reusing worn backup elements in the same stack (false economy)
Maintenance and troubleshooting (helps customers self-diagnose)
If 3128209301 / 3128 2093 01 BOOMER SEAL RING ATLAS COPCO is wearing out, you may see:
Slow drift in boom position under load
Jerky low-speed motion (stick-slip)
Oil film around cylinder areas
Rising hydraulic temperatures from internal bypass
Noise or chatter during cylinder movement
Recommended maintenance habits:
Keep oil clean (filtration is seal life)
Inspect wipers and external dust protection regularly
Avoid pressure shock events where possible (controlled valve operation helps)
Replace seal stacks as sets when wear is systemic
Compatible ATLAS COPCO / Epiroc models (where this part number shows up)
Because Boomer families include multiple configurations and revisions, compatibility is best communicated as “known references” plus “confirm with serial”.
Known references from parts listings and supplier catalogs
Atlas Copco Boomer L1C (listed as “SEAL” with this part number in a parts list)
Epiroc/Atlas Copco Boomer 282 / Boomer L2D (catalog references list this part number in Boomer-related inventory listings)
Simba S7D (listed as a cylinder seal item under this part number in a drilling rig parts listing)
Additional catalog references also associate this number with rigs such as Simba H1254 / H1354, and equipment like Boltec 235, depending on configuration and assembly group
If you’d like, you can publish the above as “commonly referenced on” and add: “Final compatibility depends on machine serial number and cylinder variant.”
Weight (KG)
Exact net weight can vary slightly by production batch and exact ring dimensions used for the cylinder variant. For e-commerce listing purposes, you can safely publish a practical range:
Estimated net weight (per ring): ~0.10–0.25 kg
Estimated shipping weight (1–2 pcs packed): ~0.30–0.60 kg
If you want the precise weight you’ll invoice/ship against, your safest workflow is: confirm the cylinder variant or the machine serial number, then we match the correct ring specification before dispatch.
