EUBO T932/22 Oil-Containing Bearing Lubricant
EUBO T932/22 is an oil-containing bearing lubricant formulated with high-quality synthetic olefin base oils, suitable for iron-based, copper-based, and iron-copper-based oil-containing bearings, as well as related powder metallurgy structural components. It is specially designed to meet the lubrication requirements of powder metallurgy oil-impregnated bearings, with viscosity grades ranging from ISO 22 to ISO 1000.
Key Features / Advantages:
-
Ash-free formulation: Prevents precipitation and sludge formation, ensuring smooth oil supply.
-
High viscosity index and excellent high/low temperature performance: Stable high-temperature oxidation resistance provides a strong oil film under elevated temperatures, enhancing coking resistance and preventing clogging of bearing micropores.
-
Anti-rust and anti-corrosion protection: Compatible with mineral oils and well-suited for sealing materials.
-
Low friction resistance: Effectively reduces abnormal temperature rise during high-speed, high-load operation, providing excellent high PV performance.
-
Noise reduction: Minimizes friction-related noise, reducing boundary friction and facilitating dry starts and frequent starts.
-
Excellent anti-wear lubrication: Significantly reduces bearing wear and prevents seizure under extreme loads.
Recommended Applications:
Widely used for lubrication of various powder metallurgy oil-impregnated bearings and micro-motor bearings.
