OT/OTB, NT/NTB, T/TB SERIES

INDIVIDUAL ROLLERS .75 - 75 TONS

ot, nt t series individual rollers
Rollers in this series are built for long life and a wide
range of operating conditions. For basic linear motion,
these rollers are used as bearing sides, conveyors, guides,
casters or dollies. Typical applications include the straight
motion required for thermal expansion under a furnace or
heat exchanger, as slides under nuclear shield doors,
upside down as a conveyor in heavy die handling carts, in
concrete forming for the casting and curing process as
well in the launching of heavy segments, attached to a
cradle for the launching of huge ships or as a heavy duty
wheel- like device to mobilize grandstand seats.
The OT type has an oversized top, the T type has a
flush top and the NT type has a long narrow top. The
top plates add extra strength to the frame and variety to
mounting capabilities, making one type ideal for cavity
mount, bolt-on or weld mount. OT and NT Rollers are
available with standard top plate sizes and mounting
hole pattern, which can be modified to customer
specifications. Elastomeric Preload Pads are available
in either fabric impregnated or neoprene form for each
roller model.
