ABSTRACT:
A roller track for a storage rack arranged for gravitational flow of load-bearing pallets having two walls disposed in parallel relation to each other and a plurality of freely rotatable rollers journalled between the walls, each on a spindle, in such manner that the rollers extend upwardly from a space between the walls. Each wall has a separate aperture associated with a respective one of the rollers. Each roller is journalled on a spindle. Each end of the spindle has a shoulder portion larger than the associated aperture. Also, each end of the spindle has a pintle portion extending outwardly through the associated aperture, beyond the outer surface of the wall having the associated aperture. The roller track further has structures for securing at least some of the pintle portions to each wall where the secured pintle portions extend outwardly beyond the planes defined by the outer surfaces of such wall. These structures may have deformed ends of the secured pintle portions, welds between the pintle portions secured to each wall and the outer surface of such wall, or fasteners fastened to the secured pintle portions. Each fastener may be a snap ring seated in an annular groove in one of the secured pintle portions, a pin passing through an aperture in one of the secured pintle portions, or a locking end cap fitted over one of the secured pintle portions.
