Canada Ltd.
RENOLD Canada Ltd has been in business in
Canada for over 80 years, supplying the Canadian
market with Power Transmission Products manufactured by the RENOLD Group. The Groups
Head Office is located in Manchester, England
and has major manufacturing plants in England,
Germany, France, and USA.
The Renold organization was originated by Hans
Renold who opened a plant in 1881 in
Manchester, to manufacture an improved transmission chain which he had just invented. From
this small beginning RENOLD has grown into a
major global concern, with 16 sales and marketing subsidiaries operating world-wide in major
international markets.
Yet in spite of this global expansion RENOLD
is mindful that its success has been achieved
by providing efficient service to all its customers
at a local level who all get the advantage of personal attention from their local RENOLD Office,
backed by the experience and knowledge
the group has gained from suppling power transmission products for nearly 120 years.
It is virtually impossible to find any industrial field
where RENOLD products are not used, for
wherever things need to be moved and power
transmitted, there is a RENOLD product which
can be chosen with confidence and awareness that
it will perform reliably and efficiently during a
long working life. Whether it is the arduous duties
found in quarrying, lumber or steel industries,
the rugged precision required in automobile
engine timing, in the reliable certainty required
in operating aircraft flight control surfaces or in
the mundane carriage of goods on conveyors or
people on escalators, RENOLD products will give
total satisfaction.
This brochure describes some of those products
available from your local RENOLD office
in Canada, and they can be specified with
confidence because they all carry the RENOLD
name, the Seal of Quality, backed by 120 years of
knowledge and experience.
RENOLD has the POWER and the DRIVE for
