B-type Air Bearings
Hovair B-type air bearings are designed to lift loads vertically off
their base, then move laterally across floor surfaces to their
destination, then dropped into position. They function the same as A-type
bearings, but lift two to three times as much when pressurized.

The three stages of a B-type air bearing
Benefits of using b-type air bearings include:
B-type bearings consist of
a two-piece vulcanized body that is glued to an aluminum backing plate.
This rubber diaphragm can give a relatively high lift and operates at
higher air pressure.
B-type bearings are
preferred where low collapsed height, high lift, and capacity per
square inch are more important than wear, stability, and air
Glued assemblies are
repairable when compared to other air bearings that are vulcanized or
riveted to the backing plate.
Superior lift height over
the A-type bearing. The B-type bearing is able to lift a load up to
three times the lift height of the A-type bearing, thus making it
possible to engage a load using a "lift & pick" movement similar to a
regular pallet truck.
B-type bearings stabilize
at 30 psi instead of 15 psi. This enables load capacities of double the
A-type bearing for the same size air bearing, but requires three times
the air consumption.
B-type bearings are also
available for air pallets, platform transporters, and air beams. These
