ABSTRACT:
A conveyor ball unit for use in a conveyor track for example for moving freight material comprises a housing accommodating a conveyor ball member supported in a mounting shell member by way of a plurality of mounting balls. The mounting shell member is supported resiliently by spring means. To prevent the mounting shell member with conveyor ball member supported therein tilting in the housing under the effect of a load thereon, upon resilient deflection of the spring, with the result of the conveyor ball member becoming jammed, the conveyor ball member is supported in the mounting shell member only at an annular region thereof and the mounting shell member is itself supported on the spring means in that annular region. The spring means comprises a plurality of plate springs, with the outer periphery thereof being held in concentric relationship in the housing, thereby providing that the conveyor ball member and mounting shell member are self-centering in the housing, to reduce the risk of jamming.
