Mobilgear™ 600 XP 680 | ISO VG 680 Industrial Gear Oil South Africa
Mobilgear™ 600 XP 680 | ISO VG 680 Industrial Gear Oil South Africa
ExxonMobil · Mobil Industrial · Authorised Distributor — South Africa
Mobilgear™ 600 XP 680 is an extra high performance ISO VG 680 enclosed industrial gear oil — the heaviest grade in the Mobilgear 600 XP series. Designed for very heavily loaded, slow-speed enclosed gear drives where maximum film thickness is required, including large mining gearboxes, heavy reducers, large slow-speed conveyors and industrial equipment specifying ISO VG 680 EP gear oil. Replaces Mobilgear 636. Outstanding EP protection, seawater corrosion resistance and foam resistance. Available from Orbit Industrial — authorised Mobil distributor, South Africa.

Features & Benefits
Outstanding EP — Heavy Loads
Extra high extreme pressure and load-carrying properties for the most heavily loaded slow-speed enclosed gear drives — protecting gears and bearings under maximum torque conditions in mining and industrial applications.
Friction-Modifying Properties
Reduces power consumption and lowers bulk oil temperatures — improving energy efficiency in large industrial gearboxes where energy losses are significant at high load.
Seawater & Corrosion Resistance
Excellent protection against corrosion including seawater — suitable for marine deck machinery, heavy winches and offshore gearboxes operating in salt-laden environments.
Excellent Water Separation
Rapidly separates from water — protecting heavily loaded gear surfaces from water contamination that reduces oil film strength and accelerates corrosive wear.
Anti-Foam Performance
Strongly resistant to foaming — maintains consistent oil film in heavily loaded slow-speed gearboxes where oil churning can generate foam at oil/gear interfaces.
Long Service Life
Excellent thermal and oxidation stability extends oil service life — reducing the frequency of oil changes in large gearbox sumps where oil changes are costly and time-consuming.
Applications
Mining Gearboxes
Heavy mill gearboxes, large reducers and slow-speed enclosed drives in open pit and underground mining where the OEM specifies ISO VG 680 EP gear oil.
Heavy Industrial Drives
Large slow-speed gearboxes in cement mills, sugar mills, paper mills and heavy industrial processing plants where maximum film thickness and EP protection are required.
Marine Deck Machinery
Heavy deck winches, windlasses and mooring equipment gearboxes in marine environments — where the combination of heavy loading and seawater exposure requires ISO VG 680 with corrosion protection.
