Hayat Kimya A.S.'s Metso tissue machine, serviced by Mobil SHC™ 632 gear and bearing oil, set the new world speed record at 2,210 m/min during a 24-hour production run at the company's mill in Turkey. Mobil SHC™ 632 is part of Mobil SHC 600 Series of advanced technology synthetic lubricants designed to deliver premium performance for the challenging and diverse operating environments in pulp and paper processing.

Formulated to cope with extreme operating conditions including high speeds and steam temperatures exceeding 200°C (392°F), Mobil SHC™ 632 delivers outstanding service for the pulp and paper industry. Compared to a standard mineral oil, it provides reliable equipment protection and extended oil life, thereby minimising downtime and operating expenses to ultimately help increase productivity.

The record-setting tissue machine has been operating at full capacity since December 2010 without maintenance, downtime or oil change. Thanks to the low fluid friction characteristics of circulation and bearing oil Mobil SHC™ 632 that produces lower operating temperatures and improved gear efficiency, the oil film didn't break down and there was no equipment overheating at any point during the record-breaking run at the Yeniköy mill.

Mobil Industrial Lubricants offers an extensive range of specialised products for the pulp and paper industry, including hydraulic, compressor and gear oils to help operators increase productivity, reduce costs and deliver sustainability-related benefits. In particular, Mobilith SHC™ PM greases, designed for wet- and dry-end bearing applications, can help increase equipment availability, minimising downtime.

After seven years in operation using a range of Mobil-branded products, none of the Hayat Kimya A.S.'s Metso or PMT Italia tissue machines have required a single bearing change. The use of Mobilgrease™ XHP 222 on the roll bearings helped prevent premature component failure. Despite the repeated water contamination of the oil flow, the machines serviced with Mobil SHC™ PM 320 required neither additional maintenance nor oil change. Designed to protect bearings from corrosion and wear even in harsh (wet-end) process water environments, Mobil SHC PM 320's saved Hayat Kimya's engineers up to three days of unscheduled downtime.

"We would not have been able to achieve this remarkable milestone without Mobil Industrial Lubricants that we use throughout our operations", said Lütfi Aydin, paper group director, Hayat Kimya. "Compared to mineral alternatives, this advanced lubricants range has been instrumental in extending the life span of our machinery and used oil, helping us significantly extend oil change intervals, minimise plant downtime and reduce maintenance costs. We regularly use Signum Used Oil Analysis to help us monitor the oil condition and we always share the analysis data with ExxonMobil Field Engineers, when they visit, to get an expert opinion and best-practice usage advice."

Hayat Kimya A.S. plant operates almost exclusively with Mobil-branded lubricants. In addition to the products mentioned above, others include Mobil DTE™ 20 series, Mobil DTE 10 Excel™, Mobil DTE™ oil Series, Mobilgear™ 600 XP, Mobilux™ EP, Mobil SHC™ 600 Series, Mobil SHC PM, Mobilgrease XHP™ 222, Mobil Polyrex™ EM, Mobil Vactra™ Numbered series and Mobil Pegasus™ 705.

Rainer Lange, Mobil SHC Brand Advisor - EAME, commented: "We are pleased to have helped Hayat Kimya secure the new world speed record. We developed Mobil SHC 600 Series to enable our customers improve equipment's ability to retain high productivity rate despite heavy loads, high speeds and wet operating conditions that often hinder productivity and profitability at paper plants. The latest milestone at the Yeniköy mill demonstrates how we can work in close partnership with industrial operators to advance the plants' productivity."
