The housing of pillow block bearing, crafted from iron, is engineered to withstand heavy-load and high-vibration conditions with the structural rigidity and dimensional stability 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.

Two M16 bolts fasten the mounted bearing unit to the mounting surface, providing a secure and stable foundation that suits both new installations and direct replacement applications. M16 is a medium-to-heavy duty fastener size, associated with larger pillow block housings that support heavier shafts and are exposed to elevated radial loads or continuous vibration.

Why choose Iron for the bearing housing?

Because this pillow block bearing is specifically designed for heavy-load and high-vibration conditions, cast iron delivers superior rigidity and dimensional stability where lighter or polymer housings are prone to deformation under load, 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.

How does the M16 affect installation and compatibility?

The bolt size directly determines whether the pillow block bearing can be mounted onto an existing frame or structure without modification. An M16 bolt corresponds to a medium-to-heavy duty hole pattern associated with larger metric housings exposed to elevated radial loads or continuous vibration, so when replacing an existing unit, confirming this dimension ensures a drop-in fit. Mismatched bolt sizes may require redrilling the mounting surface or sourcing an adapter plate, adding time and cost to the installation.
