美孚greasrex 47
汽車(chē)潤(rùn)滑脂
產(chǎn)品描述
美孚greasrex 47是一種鈣復(fù)合加厚防水潤(rùn)滑脂具有良好的承載能力。它與高度精煉的礦物油和一個(gè)精心挑選的添加劑組合，以提供一個(gè)高程度的化學(xué)和熱穩(wěn)定性和額外的保護(hù)，防止腐蝕和磨損。它用于工業(yè)應(yīng)用中的普通和滾子軸承。由于其突出的性能特點(diǎn)，美孚greasrex 47適用于集中潤(rùn)滑系統(tǒng)，特別是雙線型需要壓力釋放時(shí)間短。鈣復(fù)合增稠劑使它適用于承受振動(dòng)和可能遭受虛假brinelling軸承潤(rùn)滑。美孚greasrex 47是基于礦物油的最終粘度ISO VG 150。

Mobil Greasrex 47
Automotive Grease
Product Description
Mobil Greasrex 47 is a calcium complex thickened water-resistant grease with good load carrying capability. It is blended with highly refined mineral oils and a carefully selected additive combination to provide a high degree of chemical and thermal stability and extra protection against corrosion and wear. It is used for plain and roller bearings in industrial applications. Due to its outstanding performance characteristics, Mobil Greasrex 47 is suitable for use in centralised lubricating systems, particularly the dual line type which require short pressure release time. The Calcium Complex thickener makes it suitable for the lubrication of bearings subject to vibration and likely to suffer false brinelling. Mobil Greasrex 47 is based on mineral oils with a final viscosity of ISO VG 150.

Applications
Mobil Greasrex 47 is intended for use in a variety of industrial applications. It is suitable for use in plain and roller bearings in all kinds of machinery used in the steel and concrete industries such as in bearings of rolls in continuous casting equipment, in bearings of rolls in steel mills, bearings in conveyor lines for the transport of hot rolling material. Also for the lubrication of rotating furnaces in the concrete industry. Mobil Greasrex 47 is suitable for use in centralised lubricating systems, particularly the dual line type which require short pressure release time. It is also suitable for the lubrication of bearings subject to vibration and likely to suffer false brinelling. Mobil Greasrex 47 is resistant to hardening during storage even under the effect of thermal stresses. The operating temperatures are between -20°C and 120°C. With frequent re-greasing the operating temperatures may go up to 150°C. Mobil Greasrex 47 should not be mixed with other greases without advice from ExxonMobil.
