The housing of pillow block bearing, crafted from stainless steel, is engineered to withstand washdown, food-grade, and marine conditions with the high corrosion resistance and hygienic structural strength needed to keep the overall mounted bearing assembly performing reliably over the long term.
Shaft retention is achieved through eccentric collar locking in this pillow block bearing unit, which secures the shaft reliably against moderate loads and intermittent vibration — provided the collar is rotated firmly in the direction of shaft rotation and the locking screw is fully tightened — without damaging the shaft surface.

Why choose Stainless Steel for the bearing housing?

Because this pillow block bearing is specifically designed for washdown, food-grade, or marine conditions, stainless steel delivers high corrosion resistance combined with structural strength where standard carbon steel or cast iron housings are prone to rust and contamination risk, making it a purpose-built choice for this application rather than a generic substitute.

Why does this bearing use Eccentric Collar Locking to secure the shaft?

Eccentric collar locking works by rotating an offset collar in the direction of shaft rotation until it clamps firmly around the shaft, which makes it well suited to applications where the shaft surface must remain undamaged and load distribution needs to be more even. Its main advantage over other shaft locking methods is a broader contact area that reduces shaft stress, which matters most when the application involves intermittent loads, frequent starts and stops, or softer shaft materials.
