Abstract
A roller track for a storage rack arranged for gravitational flow of load-bearing pallets. Freely rotatable rollers are journalled, each on a spindle, between two parallel walls. Rollers of a first group are journalled on spindles bolted to the walls. Rollers of a second group are journalled on spindles held by but not bolted to the walls. Each of the latter spindles has, at each end, a shoulder portion larger than an aperture in one of the walls and a pintle portion fitted into the aperture. The pintle portion has a cylindrical wall and the aperture has a cylindrical margin. Along at least a substantial portion of the roller track, every third roller is a roller of the first group while every other roller is a roller of the second group.
