Mobil™ SHC 600 Series — Synthetic Gear & Bearing Oil
Mobil SHC 630
Exceptional Performance Synthetic Gear & Bearing Oil | ISO VG 220 | DIN 51517-3
Product Overview
Mobil SHC 630 is an exceptional performance synthetic gear and bearing oil formulated from proprietary PAO base stocks for demanding enclosed gear and bearing applications requiring ISO VG 220 lubrication. ISO VG 220 is the most widely specified industrial gear oil grade in South Africa — and Mobil SHC 630 delivers the full performance of the SHC 600 Series at this grade: Flender and SEW approval, FZG scuffing Stage 13+, FE8 roller wear of 2 mg, RPVOT 2,500 minutes, TOST oxidation life exceeding 10,000 hours, and a pour point of -48°C.
The PAO synthetic base stock provides a viscosity index of 169 — substantially higher than mineral gear oils at ISO 220 — delivering more stable viscosity across the operating temperature range, superior film protection at elevated temperatures and reliable cold-start lubrication in remote or cold-climate applications. Particularly effective in applications where the maintenance costs of component replacement, system cleaning and lubricant changes are high.
Additionally approved for oil-flooded rotary screw compressors handling natural gas, field gas gathering and CO2 — a dual capability that simplifies lubricant inventory management for operations running both gearboxes and gas compressors on the same site. Note: Mobil SHC 630 has an orange colour, distinguishing it from mineral gear oils and the clear Mobilgear 600 XP Series.
Mobil SHC 600 Series — Grade Selection
All SHC 600 Series grades are fully synthetic PAO — select by viscosity grade specified in your gearbox OEM manual
| Grade | ISO VG | VI | Pour Point |
|---|---|---|---|
| SHC 630 — This product | 220 | 169 | -48°C |
| SHC 632 | 320 | 172 | -48°C |
| SHC 634 | 460 | 174 | -45°C |
| SHC 636 | 680 | 181 | -45°C |
| SHC 639 | 1000 | 184 | -42°C |
Always confirm from your gearbox OEM service manual. Contact Orbit Industrial for grade selection assistance.
Key Performance Benefits
Outstanding Oxidation Stability
RPVOT 2,500 minutes and TOST 10,000+ hours — outstanding oxidation and thermal stability. Particularly effective in remotely located gearboxes where oil change-out is difficult, filled-for-life drives, and applications where the maintenance cost of oil changes is high.
FZG Stage 13+ & EP Protection
FZG scuffing Stage 13+ and FE8 roller wear of 2 mg — strong protection against gear scuffing and bearing wear under sustained high loads. Particularly valuable in processing plant gearboxes running continuous shifts under elevated torque.
Wide Temperature Range
Viscosity index of 169 and pour point of -48°C — superior to mineral gear oils at this grade. Maintains stable viscosity from cold overnight startups through elevated operating temperatures in high-ambient mining environments, and enables reliable cold-start performance in remote or low-temperature applications.
Gas Compressor Capability
Approved for oil-flooded rotary screw compressors compressing natural gas, field gas, CO2 and other process gases. Allows operations with both gearboxes and gas compressors to consolidate to a single ISO VG 220 synthetic lubricant across equipment types.
Energy Efficiency
Low traction coefficient of the PAO base stock reduces fluid friction in gear contacts and rolling element bearing load zones — up to 3.6% energy efficiency improvement versus mineral equivalents in controlled worm gearbox testing. Efficiency improvements will vary based on operating conditions and application.
Shear Stability & Seal Compatibility
Virtually no viscosity loss under mechanical shear in heavily loaded gear and bearing applications. Generally compatible with most NBR, FKM and other elastomeric seal materials used with mineral oils — however, substantial variations in elastomer response are possible. Consult your equipment supplier or seal manufacturer to verify compatibility before converting a system.
Typical Applications
Mobil SHC 630 is recommended where ISO VG 220 is OEM-specified and where operating conditions — elevated temperatures, remote locations, gas compressor duty or high maintenance costs — justify a synthetic formulation:
Mining & Processing Plants
Conveyor head drives and processing plant enclosed gearboxes · Agitator and mixer drives · Screen drives · Flender and SEW gearboxes in high-temperature environments where mineral oil life is limiting · Mixer roll bearings and roll neck bearings where high temperatures are encountered
Gas Compressors
Oil-flooded rotary screw compressors compressing natural gas · Field gas gathering applications · CO2 compression · Other process gas applications — enables lubricant consolidation at ISO VG 220 across gearboxes and compressors on the same site
Remote & Filled-for-Life Applications
Filled-for-life gearboxes — especially high-ratio, low-efficiency worm gears · Remotely located gearboxes where oil change-out is difficult · Low-temperature applications where cold-start performance of mineral oil is inadequate · Applications where maintenance costs of oil changes are high
Severe Industrial Applications
Severe centrifuge applications including marine centrifuges · Plastic calenders · Railroad A/C traction drives · Any ISO VG 220 application where conventional lubricants give unsatisfactory service life or where improved efficiency is desired
