2025 Sakai 84" (15 ton) SW994ND Vibe & Osc Roller

The SAKAI SW994ND is a specialized, high-performance double drum asphalt roller engineered for advanced paving where precision and adaptability are paramount. The operator can select between vibration and/or oscillation, with the unique ability to oscillate in both drums simultaneously. Our oscillation is uniquely gear-driven which reduces maintenance compared to some competitors’ belt-driven designs. Oscillation allows for achieving critical density and superior smoothness in specialized applications such as thin lift compaction, paving on bridge decks, near sensitive structures or utilities, and perfecting watertight joints, all without damaging underlying infrastructure. Powered by a reliable Cummins diesel engine, and weighing just under 15 tons with wide 84-inch drums, unlike most rollers on the market, its low center of gravity provides exceptional stability and a confident feel. Engineered for reliability, durability, and ease of use, the SW994ND is designed for maximum uptime and operator efficiency. The 180-degree operator station easily rotates via a convenient foot pedal for quick locking and unlocking. This design provides unmatched visibility and control, complemented by intuitive, physical switches and knobs that simplify operation. The heavy-duty hitch design contributes significantly to the machine’s robust construction and extended service life, a hallmark of SAKAI durability. A triple-filtered spray system with durable metal nozzles ensures consistent drum wetting, preventing asphalt pickup and contributing to a smooth, high-quality finish. Choose the oscillatory SW994ND for a powerful and dependable solution for your heaviest asphalt compaction needs.

Best Compaction Quality and Efficiency

• SAKAI’s new ECO Mode reduces fuel consumption up to 10%.

• SW994 standard model features 4,000vpm high frequency vibration, which achieves the desired density faster and more efficiently while creating a smoother finish.

• EXACT COMPACT METER matches speed for obtaining the correct number of IPF (impacts per foot)

• Frequency and amplitude modes can be switched from the seat

• Cross-mounted drive and vibration motors eliminate machine torque on the mat

• Counter rotation of eccentric weights in the drums cancel horizontal force

• Timer, auto or constant operated water spray system

Dual Drum Oscillation “Osc” & Vibration “Vibe”

• Versatility by switching on the fly from Vibe for high compaction efforts to Osc for smooth finish of the pavement surface

• Optimized dual drum Osc achieves target density of thin lift pavement (1-1.5”) in fewer passes and increases paving train speed

• Osc achieves density on no-vibe jobs where structural integrity is a concern

Operator Comfort

• 180? easy rotating operator station

• Lunch box table and cup holder

• Excellent drum edge visibility from the operator seat

• Digital programmable cruise control

Standard Safety Equipment

• ROPS

• SAKAI proprietary emergency brake pedal which kills the engine and stops the machine instantly.

• 3 inch retractable seat belt

• 39 inches of visibility to the front and rear from the operators seat

• Low profile design for low center of gravity

• Operator deck guard rails

• Horn and backup alarm

• Electric parking brake w/ interlock

Easy Maintenance

• Sprinkler system with plastic water tanks, triple-filtration, removable brass nozzles for ease of maintenance with pressurized winterization
