Manufacturer:
The Middleby Marshall 57321 Pillow Block Bearing with a 1-7/16” bore is used in ovens such as PS555, PS570G, PS770, and PS870. This bearing offers antifriction support to the rotating parts and ensures great performance of the oven conveyor system. This is because it reduces rubbing and tear of the surfaces in contact and thus increases on the service life of the components and reduces the interval for maintenance. Since the conveyor belt requires constant movement, this pillow block bearing ensures high efficiency and productivity in oven production to give consistent cooking results hence making it a essential component.
