Bri-Mac have just completed the manufacture of two cast
iron bearing housings to suit a cement production application. We
produced the fully machined housings and seals from incomplete
drawings. We produced pattern equipment, made castings and machined
them to a high specification - all inside a tight delivery time.
We have just completed the production of a large order
from India to produce split, oil lubricated bearing housings in steel.
Again, cast iron bearing housings originally chosen for the heavy
application were not strong enough and we received a call from an
Indian customer requesting stronger bearing housings suitable for heavy
work. Added to this, we also re-designed the housings to suit special
shaft sizes and specially located oil drain holes.
A flame-cut steel bearing housing and end cover was
produced for an important Portuguese customer. Originally produced as a
cast iron casting, we needed to produce them in steel as the previous
castings were no longer available. Our CNC production is now set-up to
produce these in large volumes when required.
Traditionally, tubular or twin bearing housings for fans
have been made in cast iron. However, when a British customer requested
a special fabricated housing in steel, we produced several to a high
specification. We supplied not only the fan bearing housing, but also
the end covers and oil flingers.
Producing two large cast steel bearing housings for a
heavy crushing application was not a problem. The customer had the
bearing: 23084 cck and no housing. We designed and manufactured the
bearing housings from new pattern equipment inside 8 weeks. "We see the
mineral crushing and metal re-cycling industry as very important
markets for us - and we will be concentrating on this in 2009",
explained Paul McCairn.
Bri-Mac have come to the rescue of an Argentinean mine -
and are producing large FSAFS 540 cast steel bearing housings. These
are split bearing housings with solid bases to give extra strength.
Used on lifting gear, the original housings had failed. An internet
enquiry led the customer to Bri-Mac. "We are particularly proud of our
efforts. From initial quotation, design and manufacture, my production
team have done a great job in producing these large bearing housings
for a satisfied customer", said Dave Holdnall, Production Manager.
This picture shows a SG iron bearing housing type SD
3048 with special taconite seals. A customer in Germany found it
difficult to get them made and Bri-Mac responded in good time.
After receiving a call from a German cement works, the
Bri-Mac sales team received an urgent order to produce two off SN 648
housings in cast steel. With a special base length of 790 mm and
weighing 500 kg each, we produced new pattern equipment giving extra
strength to the housing base and four hold down bolts in the cap to
suit the demanding and hostile working conditions in the cement works.
"We hope to work closely in the future with our customer on similar
projects", said Andy Holdnall, Chief Designer.
Self aligning bearing housing in SG iron. We produced a
batch of 48 off self aligning bearing housings for a steel mill in the
Far East. The inner cartridge was made from SG Iron to suit a 225 mm
Special bearing housing with a white metal lined bore.
After the original housing had worn out, we were approached by a
Turkish company to manufacture replacements. The housing shown was made
from cast iron and the bore was white metal lined to suit a 150 mm bore.
Stainless steel bearing housing for the Gulf. During
November Bri-Mac exported 12 high-value stainless steel bearing
housings to Bahrain. The bearing housings were cast in high grade
stainless steel and machined in-house. "We are looking to grow our
exports of this type of bearing housing, and the Arabian Gulf offers
many new opportunities for us to achieve this", remarked Lee Jukes,
Bri-Mac Export production.
When the big bearing companies of the world could not
help, Bri-Mac received a valued order for two off cast iron bearing
housings to suit bearing: 230/500 K. With special labyrinth seals both
sides, and a casting weighing of 1000 kg, Bri-Mac shipped these bearing
housings to Germany to a very happy customer.
"Yet again, a customer could locate the bearing - but the bearing
housing proved more difficult. We produced fully machined castings in a
time scale no other company could match. We also hope to win the next
order for 10 pieces", added a delighted Gail McCairn, Bri-Mac Export
A call from a customer in Belgium resulted in an order
for two off special cast iron bearing housings weighing 745 kg each.
The customer had a non-standard bearing - but no bearing housing to
suit, "We managed to produce bearing housings from our standard range,
and machine it special to suit a special sized bearing", commented Matt
Darby, Bri-Mac export production.
Cast steel bearing housings SBDS 2228 were produced for
an important French customer. Bri-Mac manufactured 16 housings of which
eight were through shaft and eight were blank shaft. The customer
required the housings to have extra strength and so we designed them
with solid bases. We have been informed that future orders will result
from this work.
The biggest bearing housing yet! The picture shows the
pattern equipment. The casting will weigh 2000 kg. These bearing
housings are for the mining industry and are currently in production.
The project for Canada will help Bri-Mac to crack a very lucrative and
challenging market place. "Large bearing housings for the mining
industry is an area we are concentrating on right now", commented Paul
McCairn, Managing Director.
Bri-Mac have supplied special bearing housings to suit a
high temperature application. Our sales team received a call from a
bakery in Scotland to produce steel bearing housings with special inner
cartridges with the facility to float in the housing bore under
excessive increases in heat. Previously, the bakery had acute problems
with bearing and housing failure. "We looked at our customer's
challenge, and came up with a solution which helped keep production at
100 %. The bakery are looking at implementing our design throughout
their other installations. We are pleased to help", said David
Bottomley, Bri-Mac design team.
Bri-Mac bearing housings reach Australia. We have
supplied one of the biggest steel mills in Australia with special
bearing housings to suit a harsh application. Our customer required
SSNT 230 cast steel bearing housings to suit bearing 22230 cc. The base
had to be solid and not hollow to increase the strength. After also
designing the housing to receive special seals, the bearing housings
required a very special paint finish to withstand the aggressive acidic
atmosphere. The purchase order amounted to 98 off.
Bri-Mac have manufactured a large cast iron bearing
housing weighing over 1500 kg. After successfully winning the order
from a Swedish wood mill, Bri-Mac set to work on a special design to
accommodate an obsolete bearing size. "This is yet another example of
how important bearing housings are", commented Paul McCairn. "With
special labyrinth seals both sides, we designed a cast iron bearing
housing strong enough to deal with extreme loads."
The Bri-Mac Export Sales team had a call from a customer
in France. They needed a special fan housing - complete with end
covers. The housing had been obsolete for 10 years. Bri-Mac moved
quickly to produce a new design. New pattern equipment was produced and
castings made soon after. Bri-Mac were very soon able to supply a
bearing housing to a delighted customer.
