A cross-drilled lubrication collar clamped co-axially alongside a generally conventional self-contained sealed bearing sprocket-idler assembly of a conveyor in an agricultural machine permits supplementary lubrication of the idler bearing from an external source in situ without disassembling the bearing. Clearance between the bores of the lubrication collar and the idler inner race and the spindle supporting the two elements and providing means for clamping them together, permits lubricant introduced by way of the cross-drilling in the collar to flow along the spindle and, by way of a cross-drilling in the inner race of the idler bearing, to the bearing surfaces themselves. |
