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 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, 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. Extended drain intervals achievable with Mobil SHC 630 directly reduce the frequency and cost of oil changes in continuous-operation gearboxes.
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.
Key Performance Benefits
Extended Drain Intervals
RPVOT 2,500 minutes and TOST 10,000+ hours — outstanding oxidation resistance enabling significantly longer drain intervals than mineral Mobilgear 600 XP 220. Critical for continuous-operation conveyor drives, processing plant gearboxes and any equipment where oil changes cause production downtime.
Superior EP & Bearing 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 to elevated operating temperatures in high-ambient mining environments.
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 reduces fluid friction in gear contacts and rolling element bearings — up to 3.6% energy efficiency improvement vs mineral equivalents in controlled testing. Meaningful savings across large gearbox fleets running extended shift cycles.
Shear Stability & Seal Compatibility
Virtually no viscosity loss under mechanical shear in heavily loaded gear and bearing applications. Compatible with most NBR, FKM and other elastomeric seal materials — maintains seal integrity and prevents lubricant leakage across extended service intervals.
Typical Applications
Mobil SHC 630 is recommended where ISO VG 220 is OEM-specified and where operating conditions — extended drain targets, continuous shifts, elevated temperatures or gas compressor duty — justify a synthetic formulation over mineral Mobilgear 600 XP 220:
Mining & Processing Plants
Conveyor head drives running extended shifts where drain interval reduction is a target · Processing plant enclosed gearboxes under continuous load · Agitator and mixer drives · Screen drives · Flender and SEW gearboxes in high-temperature environments where mineral oil life is limiting
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
Extended Drain Applications
Any ISO VG 220 gearbox application where the target is to extend drain intervals beyond what mineral Mobilgear 600 XP 220 can support — particularly inaccessible or elevated gearboxes, filled-for-life drives, and equipment where each oil change requires extended production shutdown
Remote & Temperature-Critical Applications
Remote mining sites with cold overnight temperatures where mineral ISO VG 220 may struggle at startup · High-altitude processing plants with large temperature variation · Applications in the Northern Cape where summer ambient temperatures push gearbox sump temperatures above mineral oil limits
