- Pack size: 18 kg bucket
- Also available in: 390 g cartridge, 50 kg drum, 180 kg drum
Applications
Mobil Centaur XHP 221 is recommended for lubrication of rolling element bearings in machinery operating at high temperatures where resistance to water washing and corrosion are important. Specific examples of such applications include :
- Wet-end paper machine bearings
- Heavily loaded industrial ball and roller bearings
- Bearings in steel mill and mining operations
Specifications & Approvals
- DIN 51825: 2004-06 KPF1-2G-20
Benefits
- The calcium sulphonate thickener system protects against water washout and bearing corrosion under challenging conditions
- Resists softening under mechanical shear in the presence of process water contamination
- Excellent extreme pressure protection at low to moderate speeds is provided by the grease thickener system
- Resists oxidation and oil separation at high temperatures, and provides excellent life in accelerated bearing life tests
