Bearing Housing & Units

Screw drive bearing arrangements are subjected to requirements that often cannot be optimally fulfilled by the design construction of conventional bearings.

The 4 hole flange bearing design allows installation in various applications and is suitable for very high radial loads.

Plummer block housings are applicable with both high-capacity spherical roller bearings and self-aligning ball bearings. Manufactured by ISB in Italy from high-strength cast steel or ductile steel with bore diameter range of 10-620.

Self-aligning ball bearings have a spherical raceway in the outer ring with a center of curvature matched with the bearing center. This allows the inner ring, balls, and cage to rotate freely around the bearing center, maintaining alignment.

Housing units support your bearings by protecting them from contaminants and reducing damage.

UCP Pillow blocks are designed to provide shaft support where the mounting surface is parallel to the shaft axis and the adjustment during mounting is made through the slotted holes.

Including triple seal design for severe contamination conditions, stainless steel units for corrosive environments, and high durability bearings for demanding applications.

ISB Agricultural bearing units can be supplied complete with bearing. The latter is comprised of an outer spherical ring that can oscillate in the corresponding raceway in the bearing unit, so as to mitigate any alignment defects and eliminate stress between the shaft and the bearing unit.

PFI’s range of Agri-Hubs are a high performance, long-life bearing solution for your agricultural applications.

The ISB Agri Hub offers a low-maintenance, unitised, sealed bearing unit with benefits for both end users and original equipment manufacturers.
