Housing & Units

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

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

The main feature of ISB cast iron bearing units is their ability to support heavy loads without generating vibrations.

The ISB greasers and oilers are made of transparent Lexan®, a plastic material with high mechanical, chemical and thermal resistance; this solution allows to control the consumption of the lubricant at any time.

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

ISB plastic bearing units allow silent machine operation and high energy savings. ISB plastic bearing units can be supplied in various forms: two-piece, square flange, round flange, oval flange, sliding, hanging, tap base, with bracket.

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.

Radial insert ball bearings are single-row, ready-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides with cages made from plastic or sheet metal.

The bearings used in ISB housings provide a sealing system on both sides.

Bearing housings support your bearings. Protecting them from contaminants while holding in lubricant.

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

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

Flange blocks (UCF) have a 4-bolt mounting system, typically used when the shaft passes through the machine at a right angle.

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.
