RENO RINGS are the most universally applicable retaining system. Transferring
large axial load from the located component onto the groove wall, the ring
simply acts as a shoulder when mounted on a groove of a shaft or bore. Several
types of rings are available to fit to various applications.
SPECIAL METALLIC FASTENERS
TTB develops special fasteners for a very broad range of
applications to meet customer requirements. The development of Tool Design,
Process Specification, Heat Treatment, Surface Finish and Packing are made to
guarantee all customer requirements.
Applied on shaft and bores, Snap Rings are the retaining system that present the
smallest radial width, providing application where space is limited and where
the lug’s of a retaining ring cannot be applied. Its performance is generally
inferior to the retaining rings due to its even section which provides uneven
stress within the rings when closed down or expanded.
Washers are primarily used as a seat to distribute load, but it may also provide
spring tension, span oversize holes, insulate, seal, lock fasteners, protect
surface, or provide electrical connection. Several types of washers are
available : flat, conical and helical spring washers, tooth lockwashers and
Compressed when driven into the hole, the pins exert spring pressure against the
hole wall along its entire engaged length to develop locking action. Two types
of spring pins are available : slotted and spiral. Both forms are made to
controll diameters greater than the holes into which they are pressed. Spring
pins are available for very light, medium and heavy-duty applications for use in
both metals and plastics.
Disc Springs are the best solution when the application requires very high load
in a confined space and short travel. Applied singly or in stacks, it is the
best way to replace a coil spring to achieve the required load and travel under
restrained design conditions. Disc spring applications are typically : Clutches,
transmissions, braking systems. Valves, piping - Heavy engineering applications.
TTB is one of the technology leaders in the manufacturing of
speed nuts. Besides speed nuts, a large variety of fastening elements with one
or multi-threads are manufactured in various material types for use in
electronic equipments, household appliances, illumination industry and
