Solution

MARINE CRANES



Slewing bearings can simultaneously bear axial force, radial force, and overturning moment, offering flexible operation. The double-row ball series slewing bearings, in particular, effectively increase load-bearing capacity and overall performance within similar dimensions.

The fully enclosed units of the series of slewing reducers offer an IP65 protection rating, effectively extending product lifespan in harsh environments. They are easy to install and highly reliable.

ARI SLEW RING offers a complete range of slewing bearings and reducers, with mounting diameters from 100-5000mm, suitable for small marine cranes. For heavy-duty cargo ships or crane bearings, ARI SLEW RING can also customize and manufacture them.

ACCESS PLATFORMS



For aerial work platforms or high-altitude window cleaning machines, absolute safety and minimal terminal sway must be guaranteed. ARI SLEW RING offers precision slewing drive with reverse self-locking, and rotation accuracy can be controlled within 0.03-0.1°.

ARI SLEW RING's proprietary reverse self-locking slewing drive effectively improves product stability and safety.

MODULAR TRANSPORTER



Steering system of large beam transport vehicle: In order to withstand large axial forces and overturning moments, it is also necessary to ensure the consistency of the simultaneous rotation of multiple wheels. The ARI SLEW RING dual worm gear slewing drive device, with its special tooth structure and transmission method, can meet these requirements. Sufficient torque and consistency ensure the accurate and stable operation of the steering mechanism.

OFFSHORE OIL & GAS



ARI SLEW RING’s products are widely used on offshore oil and gas platforms. Their three-row ball and double-row ball slewing bearings can withstand greater axial forces and overturning moments within the same volume, effectively ensuring platform maneuverability. ARI SLEW RING also offers customizable slewing drives and reducers with a fully sealed design, achieving an IP65 protection rating and a C3 H corrosion resistance rating, requiring no maintenance for ten years.

ARI SLEW RING boasts an excellent design team and superior manufacturing processes, producing a range of cost-effective products. We also supply shipyards worldwide for installation in davit cranes, ROV handling systems, and mooring systems.

WATER TREATMENT & PROCESS EQUIPMENT

The large slewing bearings and agitator slewing drives used in wastewater treatment equipment feature special design, processing, and surface corrosion protection, extending product lifespan even in harsh environments.

ARI SLEW RING can not only manufacture products according to measurements or drawings, but also redesign new products based on their specific characteristics.

HIGH PRECISION SLEW BEARING




ARI SLEW RING manufactures high-precision rotary drives that can achieve synchronous tracking in both horizontal and vertical directions with a tracking accuracy of less than or equal to 0.01°, serving civilian and military radar systems as well as radio telescopes.

TUNNELING MACHINE

Extra-large diameter slewing bearings are also within our production range. To date, our large-diameter slewing bearings have been used globally in construction, mining equipment, and cantilever cranes.

ARI SLEW RING offers slewing bearings up to 11,000 mm in diameter, and our segmented slewing bearings facilitate transportation and on-site assembly.

MOUNTED TRUCK CRANE

ARI SLEW RING's four-point contact ball bearings can simultaneously bear axial force, radial force, and overturning moment while operating flexibly. In truck-mounted cranes, single-row external tooth four-point ball slewing bearings are commonly used, while double-row external tooth four-point contact ball slewing bearings offer higher load-bearing capacity compared to other products of the same size. ARI's truck-mounted crane slewing bearings are made of high-quality alloy steel, resulting in low noise, long service life, and easy installation.
