Units to North American standards

Pillow block units

Pillow block unit, P2B series

Pillow block units use cast iron housings. They are supplied with a grease fitting for relubrication and have slotted bolt holes for adjustment during installation. Three series are available:

  • The P2B series has a standard base-to-center height.
  • The P2BL series features a low base-to-center height, typically 1/16 in. lower than the P2B series.
  • P2BM is the medium-duty series. The housings accommodate a larger bearing for a given shaft size, resulting in a greater load carrying capacity. 
You can find these units in the product table by filtering for 'North American standard'.

Tapped based units

P2BT set screw tapped base unit

Tapped base units (P2BT series) are a variation of pillow blocks, optimized for applications where space is limited. They use cast iron housings and are supplied with a grease fitting for relubrication.
