Mobil SHC™ Gear Series — Supreme Performance Synthetic Gear Oil
Mobil SHC™ Gear 3200
Supreme Performance Synthetic Gear & Bearing Oil | ISO VG 3200 | Slow-Speed High-Load
Extreme High Viscosity — Boundary Lubrication Regime
Mobil SHC Gear 3200 is the ISO VG 3200 grade in ExxonMobil's SHC Gear series — a supreme performance synthetic gear oil for very slow-speed, high-load enclosed gear drives and plain and rolling element bearings where conventional products operate in the boundary lubrication regime and give unsatisfactory service life.
At ISO VG 3200, this product is specifically engineered for applications where extremely high viscosity is required to maintain adequate EHL film thickness at very slow shaft speeds and very high loads — including railroad DC traction motor drives, certain open gear applications such as oiling pinions or specially designed circulation systems, and any industrial enclosed gear application where the OEM specifies ISO VG 3200. FZG Stage 13+ and four-ball weld load 250 kgf confirm outstanding EP and anti-wear performance even in boundary-regime conditions.
Product Overview
Mobil SHC™ Gear 3200 is a supreme performance heavy-duty synthetic gear oil designed for all kinds of enclosed steel-on-steel gear drives as well as plain and rolling element bearings — particularly where very high viscosity grades are required for slow-speed, high-load and high-temperature applications. Formulated from synthetic base fluids with exceptional oxidation and thermal properties and excellent low-temperature fluidity.
The combination of a naturally high viscosity index (165) and a unique additive system provides outstanding performance under severe high and low temperature operating conditions. The synthetic base stocks have inherently low traction properties that result in low fluid friction in the load zone — helping to produce lower operating temperatures and improved gear efficiency versus mineral oils of comparable viscosity.
Application note: While compatible with mineral oil based products, admixture may detract from performance. Systems should be thoroughly cleaned and flushed when replacing a mineral product to achieve maximum performance benefits. Supplied in 176kg drum from Orbit Industrial — authorised Mobil sales agent, South Africa.
SHC Gear 1500 / 3200 / 6800 — Grade Selection
All three grades use the same supreme performance synthetic formulation — select by ISO VG grade from your OEM nameplate
| Grade | ISO VG | KV@40°C | VI | Pour Point |
|---|---|---|---|---|
| SHC Gear 1500 | 1500 | 1500 | 165 | -18°C |
| SHC Gear 3200 — This product | 3200 | 3200 | 165 | -9°C |
| SHC Gear 6800 | 6800 | 8200 | 180 | -6°C |
Always confirm the correct grade from your gearbox OEM nameplate or service manual before ordering.
Performance Benefits
Outstanding Load-Carrying & Anti-Wear
Proprietary additive combination provides excellent gear scuffing protection and anti-wear performance even in shock load situations. FZG Stage 13+ and four-ball weld load 250 kgf — helps extend gear life and reduce maintenance costs in slow-speed high-load enclosed gear drives.
Excellent EHL Film at Slow Speeds
Very high viscosity provides excellent EHL film protection of gears and bearings even at slow speeds, high loads and high temperatures — covering the boundary lubrication conditions where conventional lower-viscosity products give unsatisfactory service life.
High Viscosity Index — 165
VI 165 provides trouble-free operation over a wide temperature range — particularly at extremely low temperatures where conventional very high viscosity mineral products become unworkably stiff and cannot circulate to the lubrication points.
Low Traction — Improved Gear Efficiency
Synthetic base stocks have inherently low traction properties — resulting in low fluid friction in the load zone of gears and rolling element bearings. Can help improve gear efficiency and lower operating temperatures, leading to lower operating costs versus mineral oils of equivalent viscosity grade.
Outstanding Thermal & Oxidation Resistance
Exceptional thermal and oxidative stability helps reduce lubricant consumption and change-out frequency — reducing product and change-out costs in enclosed gear drives where oil changes require significant downtime and maintenance labour.
Light Colour — Easy Inspection
Light colour helps avoid the need for gear cleaning prior to inspections — reducing maintenance costs and simplifying gear condition monitoring versus dark mineral oils or asphaltic products that obscure gear tooth surfaces.
Recommended Applications
Suitable for both circulation and splash lubrication systems. Particularly recommended for gear sets operating under heavy or shock loads and low speeds where boundary lubrication may prevail:
Industrial Enclosed Spur, Helical & Bevel Gears
Slow-speed and/or high-load enclosed industrial gear drives where ISO VG 3200 is OEM-specified — particularly drives operating in the boundary lubrication regime where conventional products give unsatisfactory service life
Plain & Rolling Element Bearings
Slow-speed and/or high-load plain and rolling element bearing applications where extreme high viscosity is required to maintain adequate film thickness — particularly bearings operating at very slow speeds under sustained heavy load
Railroad DC Traction Motor Drives
Railroad DC traction motor gear drives where ISO VG 3200 is specified — a specific application noted in ExxonMobil documentation for the SHC Gear 3200 and 6800 grades
Certain Open Gear Applications
Certain open gear applications such as oiling pinions or specially designed circulation systems — where a light-coloured synthetic product is required rather than asphaltic open gear lubricants, enabling visual gear tooth inspection
