Y-Bearings Grease Fill

Y-Bearings Grease Fill

Standard SKF Y-bearings and Y-bearing units are filled with a high-quality, long-lasting mineral oil based grease that has a lithium-calcium thickener. This grease has a consistency of 2 on the NLGI scale. This grease is extremely water resistant and will provide long service life even under heavy loads. The properties of this grease are listed in table.

YAR 2-2RF/HV series Y-bearings made of stainless steel and YAR 2-2RF/VE495 series Y-bearings with zinc coated rings and stainless steel flingers are filled with a special food-grade grease. This grease fulfils the requirements listed in the Guidelines of section 21 CFR 178.3570 of the FDA (US Food and Drug Administration) regulations. It is approved by the USDA (United States Department of Agriculture) for Category H1 use (occasional contact with food stuffs). This food-grade grease shows very good rust inhibiting properties, good water resistance and antiwear characteristics as well as high ageing and oxidation resistance. The properties of this grease are listed in table.

Y-bearings with a square or hexagonal bore are filled with a premium quality grease, which has good water and corrosion resistant properties and provides excellent lubrication at high operating temperatures (designation suffix VT357). The properties of this grease are listed in table.
