How Mobil SHC™ 600 series is redefining gearbox performance for India’s cement industry.

Cement manufacturing runs on heavy rotating equipment operating continuously under high loads, elevated temperatures, and demanding duty cycles. Gearboxes sit at the centre of this, and when lubrication falls short, the consequences show up directly in energy consumption, maintenance costs and unplanned downtime.
The pressure on global supply chains today is real, and businesses across sectors are finding new ways to absorb it. For cement plants, that resilience starts at the most fundamental level — with every lubrication decision, every oil
drain interval, and every gearbox that either runs efficiently or does not. Mobil™ ensures the shop floor stays steady.
“In uncertain times, businesses need partners they can rely on without question. Mobil™’s commitment is straightforward – deliver products that perform, support teams that show up, and solutions that keep our customers productive. That has always been our promise, and it does not change with the times,” says Abhinav Jogi, General Manager – Commercial Marketing, South Asia Pacific, ExxonMobil Lubricants.

Built for the demands of heavy industrial equipment
Cement plants run some of the most demanding rotating equipment in any industrial setting, gearboxes operating continuously under high loads, severe temperatures and long duty cycles
with little tolerance for failure. Mobil SHC™ 600 Series is engineered specifically for this category of equipment.
Mobil SHC™ 600 Series synthetic lubricants can reduce energy consumption in gearboxes and circulating systems by up to 3.6 per cent*. They can also:
• Extend oil life by up to six times vs. conventional oil
• Offer similar seal and metals compatibility as conventional oils
• Operate in a wide range of applications
The series spans seven viscosity grades, from ISO VG 32 to ISO VG 1000, giving plants the flexibility to match the right grade to the right application. Mobil SHC™ 629, 630, 632, 634, 636, and 639 are approved by Siemens AG for use
in Flender gearboxes, an endorsement that
matters to plants running equipment built around that standard.

Three properties that translate into real operational gains
What separates Mobil SHC™ 600 Series from conventional gear oils comes down to three core properties:
• Superb high temperature thermal and oxidation resistance, which helps extend equipment’s high temperature operating capability
• High viscosity index and absence of wax, which helps maintain viscosity and film thickness even as temperatures climb
• Low traction coefficient, which helps reduce friction and increase efficiency in sliding mechanisms
On paper, these read as technical specifications. On the plant floor, they translate into gearboxes that run cooler, oil that lasts longer between changes, and energy that is not lost to friction it should never have had to overcome.

Proof from an Indian cement plant
These benefits are not theoretical. A cement manufacturer in Tamil Nadu was using a conventional mineral-based gear oil in a premium transmission gearbox. The oil could not handle the heavy load and friction inside the gearbox, causing it to break down faster than expected, and the plant was changing it every 2,000 hours, far more often than ideal. Using oil analysis, ExxonMobil identified that the oil’s viscosity had dropped and that
the gearbox was running hotter than it should, due to contamination.
Mobil recommended Mobil SHC™ 632, a PAO-based ISO VG 320 oil with greater viscometric properties and a low traction coefficient, delivering better film thickness at high temperatures and good flowability at low temperatures. Following the changeover, ExxonMobil’s Field Engineering Services also provided SIGNUM used oil analysis and thermal inspection to track the ongoing condition of both the equipment and the lubricant.
The results were measurable and significant**:
• 1 per cent increase in energy efficiency
• 3°C reduction in gearbox temperature
• Oil drain interval extended by four times
• Annual savings of INR 4,76,772
A 1 per cent efficiency gain may sound
modest in isolation, but on equipment that runs continuously, every day, every year, that margin compounds into meaningful savings, exactly the kind of return a plant can point to when justifying a lubricant decision.

What this means for India’s cement industry
As cement plants across India continue to face pressure on both energy costs and uptime, gearbox lubrication remains one of the most direct and controllable levers available. The results from this single Indian operation make the case clearly: the right lubricant does more than protect equipment, it actively improves the economics of running it.

*Energy efficiency relates solely to the performance of Mobil SHC 600 when compared to conventional (mineral) reference oils of the same viscosity grade in circulating and gear applications. The technology used allows up to 3.6 per cent efficiency compared to the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary based on operating conditions and application.
**This Proof of Performance is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.
