Plastic Steel® Putty (A)
Plastic Steel® Liquid (B)
Worn, missing metal damaged this large bearing race support or mating structure creating a need for a new bearing to be repositioned. Past attempts at repair included welding and machining to the required dimension, but was not successful due to high cost, heat distortion damage, and lengthy equipment downtime.
The new bearing was generously coated with Devcon Paste Release Agent, which was required for easy part separation or removal. The bearing was then positioned and leveled using jack bolts. A metal strip was tack welded around the perimeter to contain Plastic Steel Liquid and prevent migration while curing. Plastic Steel Liquid was pumped between the surfaces using a Grayco manual pump. Following full cure (24 hours), the bearing was separated from the support or mating surface using jacks. Any remaining voids, imperfections, or pinholes were filled with Plastic Steel Putty then lightly sanded.
