Before Installation: Confirm depth of 5" (125mm) clearance below the top of the conveyor
structure for the impact bed to travel while absorbing the load (Fig. 1). Inspect structure;
confirm CEMA rating. Shim bed or idlers per Table 1. NOTE: Installation of an idler is
required 1-6" (25-150mm) before and after a Flexco® DRX™ Impact Bed (Fig. 1a). If more
than one impact bed is used, idlers should be installed between every one or two beds.
If CEMA rating is unknown, measure the lead and
trail idler for height from top of center roll to the top
of conveyor structure. Table 2 shows the nominal
center height required for the idler based on belt
width. If incorrect, shim idler(s) to the height shown
in Table 2.
