Planetary Gearboxes Suppliers, Saudi Arabia

Which planetary gearbox types do Saudi mining and cement plants buy?

Saudi mining and cement plants buy large industrial planetary units for mills, kilns and conveyors, plus smaller planetary gearmotors for mixers and discharge drives. They are a core design in gears and gearboxes for Saudi industry, chosen where torque is high and floor space is limited.

Flender lists PLANUREX 2 planetary units from 117,000 to 2,600,000 Nm in 22 sizes, with nominal ratios from 25 to 4,000, and names roller presses, apron conveyors, tube mills, rotary kilns, bucket excavators, crane slewing gears and agitators as applications. SEW-EURODRIVE lists P series planetary units for roughly 24 to 500 kNm, including plate conveyors, silo discharge and mixers.

Flender notes the unit can sit behind helical, worm, bevel or bevel-helical stages, a common arrangement for big conveyors. For lower torque in-line drives, helical gearboxes cost less, and for right-angle layouts see bevel gearboxes.

Is a planetary gearbox better than a helical gearbox for heavy duty?

A planetary gearbox is better when torque density and in-line layout matter, and a helical gearbox is better when cost, simple servicing or low ratios matter. Neither is better everywhere.

• Size and weight: shared load across planets gives more torque per kilogram.
• Layout: coaxial shafts suit slew rings, wheel hubs and mixer tops.
• Cost and repair: planetary stages are more complex and costlier to overhaul.
• Load sharing: accuracy decides whether planets carry equal load, so ask makers how they handle it.

How does Saudi heat change planetary gearbox selection?

Hot desert air and direct sun cut the heat a compact gearbox can shed, so thermal capacity can limit continuous duty before strength does. Always run the thermal check at site conditions.

• Ambient: SEW-EURODRIVE says catalogue data assume 25 degrees Celsius, standard ranges often stop at 40, and operation to 60 requires adapted lubricants, seals and thermal planning.
• Cooling: large units may need an oil cooler or pump; state coolant availability on remote mine and cement sites.
• Dust: use sand-tight seals and filtered breathers, and keep cooling fins clean.
• Coast: Jubail, Yanbu and Jeddah need marine paint.
• Oil: choose grade for sump temperature; see gear oils.

What approvals apply to planetary gearboxes in Saudi Arabia?

As of 2026 a mechanical planetary gearbox has no dedicated SASO conformity scheme that we could confirm. The datasheet, lifting rules and motor certificates apply instead.

The guide to SASO and SABER certificates for industrial equipment explains shipment certificates for motors.

Who supplies planetary gearboxes in Saudi Arabia?

Supply runs through manufacturer subsidiaries, authorised distributors in Riyadh, Jeddah and Dammam, and service shops near Jubail and the mining belt. Large units are built to order and arrive via Dammam or Jeddah.

Brands on ListGCC that make planetary units include Flender, SEW-EURODRIVE, Bonfiglioli and Brevini. Confirm each maker's current range for your torque. Vetting steps are in the supplier sourcing guide for the UAE and Saudi Arabia.

What affects planetary gearbox cost and delivery in Saudi Arabia?

• Torque and size: frame size dominates price.
• Stages and ratio: extra stages add cost.
• Cooling and filtration: coolers, pumps and monitoring.
• Input package: motors, brakes, variable frequency drives.
• Documentation: witnessed tests for Aramco and mining packages.
• Logistics and local content: imports via King Abdulaziz Port in Dammam or Jeddah Islamic Port; in-Kingdom service can count toward iktva.

To get quotes, post your requirement for planetary gearboxes with torque, ratio, speed, mounting, site and ambient.

What should a Saudi planetary gearbox datasheet include?

Include torque and speed, service factor, duty hours, mounting position, output loads, ambient and sun exposure, lubrication preference and any Ex zone, plus the driven machine type. Suppliers cannot size the thermal limit without duty hours and ambient.

How do you maintain a planetary gearbox on a remote Saudi site?

Maintain it by trending oil temperature, oil condition and vibration, and by changing oil and filters on a fixed interval shortened for desert heat. A planetary unit hides its failures inside a closed housing, so condition data matters more than visual checks.

• Oil sampling: send samples for wear metals and viscosity, and compare with the first fill.
• Temperature: fit a sump sensor and alarm below the oil maker's limit.
• Vibration: take a baseline at commissioning, because planet bearing wear appears as a rise in gear mesh frequencies.
• Spares: keep seals, filters and a spare oil charge on site, and agree service response with the supplier for mine and cement locations far from Riyadh or Dammam.

Record every oil change, filter replacement and alarm in one log per gearbox. When a unit does fail, that history tells the overhaul shop whether heat, contamination or overload was the cause, and it shortens the repair quote.
