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.
