Outside contamination particles and polishing friction between a rotating shaft and a seal can, over time, result in severe shaft damage. Instead of repairing or replacing the damaged shaft, SKF® recommends using wear sleeves for heavy industrial applications (LDSLV) for shaft diameters ranging from 211.15 to 1143 mm (8.313 to 45 in). CR Seals® Wear Sleeve, Type LDSLV4, 20.813 in ID, 21.001 in OD, 2.1252 in Width, 20.813 in Shaft Diameter, Carbon Steel, Chromium Plated
