GB Series Industrial O-Ring Chain from GB Power Transmision

GB Series Industrial O-Ring Chain
GB Power Transmission has announced the arrival of the GB Series Industrial O-Ring Chain now available from stock.
Traditionally
used in the Motorcycle chain applications, customers are now realising
the true benefits of the O-Ring chain design in industrial applications
as they become more competitively priced against the benefits they
provide.
O-Ring chain in
both Motorcycle and Industrial Drive applications extend the service
life of the chain by protecting the parts of the chain that need it
most.
The O-Ring,
located at the top and bottom of the roller act as a seal for the
roller chain which keeps important elements in and other damaging
external elements out.
Originally
designed for the Motorcycle chain applications which experienced high
speeds up to 9000rpm and beyond, engineers went for a narrow style
roller chain which reduced friction and heat when meshing with the
drive sprockets.
The chain was
capable of transmission the torque and worked well within maximum
allocable load ratings however the requirement for constant maintenance
to maximise service life was apparent.
The key to
maintenance was lubrication and due to centrifugal force keeping the
lubricant in the parts that need it most was proving difficult.
The chain worked
well in the application but service life was reduced and chain
elongation a constant problem as the pin, bush and roller where not
protected enough by lubrication.
Often referred
to as the heart of the chain, the pin, bush and roller are components
that transmit the power from the sprocket tooth to the load bearing
side plates. It is this area where abrasives and corrosion attack the
chain and commence the elongation process which is then accelerated by
the load and high speed.
Engineers needed
to protect this part of the chain by keeping lubrication in and foreign
abrasives out. By placing a flexible seal at the top and bottom of the
roller which moved and flexed with the chain under load they were able
to keep the all important lubrication in and damaging foreign abrasives
out.
The end result
was a chain that offered preventative maintenance properties and
protected the parts that needed the protection most. In the field,
lubrication applied to the chain often did not penetrate the roller,
bush and pin area and actually acted to attract other damaging air
bourn abrasives.
While an O-ring
chain still requires maintenance, its original construction ensures it
created a barrier between the outside elements and the heart of the
roller chain.
In recent years,
attempts to improve chain to a zero maintenance status by introducing a
sintered and oil impregnated bush have proven expensive and also
reduced the chains load capabilities and power ratings causing customer
to have to up size existing applications already installed.
The O-Ring chain
design now available in the industrial chain sizes has become more
competitively priced when balanced to the extended service life and
reduced maintenance properties it offers.
The GB Series
Industrial O ring chains are available in the Standard Transmission
Chain sizes including American and European standards. Currently
Stocked in ½” inch ASA 40 to 1” ASA 80 and ½” BS 08B to 1” BS 16B pitch sizes the range will expand along with customers demand.
