The Atlas Copco 2903101601 (=1613958500) Coupling Element serves as a critical power transmission component designed and manufactured by Atlas Copco in Slovakia. This genuine part supersedes the earlier part number 1613958500 and delivers the same factory-engineered performance and reliability that industrial operators worldwide expect from Atlas Copco equipment.
We supply this coupling element as a brand-new, original genuine part sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. Every unit arrives in original Atlas Copco packaging and meets all original factory specifications for material composition, dimensional accuracy, and torque capacity.
Product Introduction
In a screw air compressor, the coupling element forms the mechanical bridge between the electric motor shaft and the compressor air end. It transfers rotational torque from the drive motor to the male and female screw rotors while absorbing minor shaft misalignments, dampening vibration, and cushioning torque spikes during startup and load changes. A worn, cracked, or degraded coupling element causes excessive vibration, elevated noise levels, reduced energy efficiency, and — if left unaddressed — permanent damage to bearings, shaft seals, and the air end itself.
Operators who choose genuine Atlas Copco replacement parts protect their equipment investment, preserve factory warranty conditions, and maintain consistent compressed air output quality. The 2903101601 coupling element fits a range of Atlas Copco GA-series oil-injected screw compressors and delivers a service life that outperforms aftermarket alternatives by a significant margin under identical operating conditions.

Core Functions of Coupling Element
Torque Transmission
The coupling element transfers rotational power from the motor shaft to the compressor air end with minimal energy loss. Its toothed elastomer profile maintains constant contact under load, ensuring smooth power delivery across the entire operating speed range.
Misalignment Compensation
During normal operation, thermal expansion, frame settling, and vibration introduce small amounts of axial, radial, and angular misalignment between the motor and the air end. The flexible rubber compound of the 2903101601 coupling element absorbs these deviations without generating additional mechanical stress on adjacent bearings and seals.
Vibration Damping and Shock Absorption
Every compressor startup produces an instantaneous torque spike. The elastomeric material of the coupling element cushions this shock, reduces mechanical resonance, and lowers overall noise emission. This damping effect directly extends the service life of precision components such as bearings, shaft seals, and rotor profiles.
Overload Protection
Under unexpected overload conditions, the coupling element acts as a mechanical fuse. Its designed failure threshold protects the more expensive motor and air end from catastrophic damage, reducing downtime cost and simplifying repair work.
Product Advantages
1. Factory-Engineered Precision
Atlas Copco designs and manufactures the 2903101601 coupling element in Belgium under strict ISO 9001 quality management systems. Each unit matches the exact dimensional profile, tooth geometry, and material hardness specified for the original compressor build. This precision guarantees a perfect fit, correct torque transfer, and long service life.
2. Premium Elastomer Material
The coupling element uses a high-grade, oil-resistant rubber compound formulated to withstand sustained temperatures inside the compressor cabinet. The material maintains its elasticity, tensile strength, and damping properties across thousands of operating hours, even when exposed to compressor lubricant mist and elevated ambient temperatures.
3. Extended Service Life
Genuine Atlas Copco coupling elements deliver significantly longer service intervals compared with generic aftermarket alternatives. Field experience shows that original parts routinely achieve 8,000 to 12,000 operating hours before scheduled replacement, reducing annual maintenance cost and production interruptions.
4. Full Compatibility Assurance
Because part number 2903101601 directly supersedes 1613958500, operators can install it without modification to existing coupling hubs, shafts, or alignment settings. This drop-in compatibility simplifies maintenance work and eliminates the risk of engineering errors during replacement.
5. Protection of Adjacent Components
A high-quality coupling element preserves the integrity of expensive surrounding parts. By absorbing vibration and misalignment, the 2903101601 reduces wear on motor bearings, air end bearings, and shaft seals. Over the full lifecycle of the compressor, this protection yields substantial savings in repair and replacement expenses.
Installation Steps
Proper installation ensures optimal performance and maximum service life. Follow this recommended procedure when replacing the coupling element.
Step 1: Prepare the compressor for service
Lock out and tag out the main power supply. Release all internal system pressure and allow the compressor to cool to a safe handling temperature. Remove the relevant service panel to access the coupling assembly between the motor and the air end.
Step 2: Inspect the coupling hubs
Clean both the motor-side and air-end-side coupling hubs. Check for cracks, wear on the tooth profiles, corrosion, or loose fasteners. Replace any hub that shows signs of damage or excessive wear.
Step 3: Remove the old coupling element
Slide the old coupling element out from between the two hubs. Inspect it for signs of uneven wear, cracking, or oil degradation. Document the failure pattern to help identify underlying alignment or lubrication issues.
Step 4: Verify shaft alignment
Before installing the new 2903101601 coupling element, check radial and angular alignment between the motor shaft and the air end shaft. Correct any misalignment that exceeds the manufacturer’s tolerance. Proper alignment is the single most important factor for long coupling life.
Step 5: Install the new coupling element
Lubricate the tooth profiles lightly with the recommended assembly compound if specified. Seat the new coupling element evenly onto both hubs. Ensure full engagement on both sides and confirm that the element sits centered in the gap.
Step 6: Reassemble and test
Reinstall any retaining hardware and service panels. Restore power and run the compressor under load for a minimum of 30 minutes. Monitor vibration levels and listen for unusual noise. Normal operation should be smooth and quiet.

Anonymous_buyer –
Worth every penny for the reliability we gain.
After trying a cheaper aftermarket coupling that lasted only three months, we switched to this original Atlas Copco part. It has now been running for over nine months without any issues. The rubber compound feels much more durable, and the tooth profile matches perfectly.
Shawn –
Excellent quality and fast delivery from the supplier.
We replaced a failing coupling on our GA55 compressor with this genuine 2903101601 unit, and the difference was immediately noticeable. Vibration levels dropped significantly, and the machine runs much quieter. Installation was straightforward, and the part arrived in original packaging.
Deods –
Highly recommended for industrial maintenance teams.
Our maintenance team ordered this coupling element for a scheduled service on two Atlas Copco compressors. Both units fit without any modifications, and the cross-reference from old part number 1613958500 was correct. The supplier provided clear documentation and responded quickly to our questions.
