Typical applications include conveyors, agitators, fans, pumps and agricultural machinery. In food, chemical and aggregate processing plants, these housings are chosen for their sturdy mounting and straightforward maintenance. The 4-bolt flange fastens to flat surfaces with simple alignment.
Selection depends on shaft diameter, radial and axial loads, and the operating environment. The insert bearing generally arrives pre-lubricated and fitted with seals that keep grease in and contaminants out. During installation, ensure the mounting surface is clean and flat, and tighten the bolts evenly to avoid distortion. Periodic lubrication helps extend service life.
