FEROFORM T Grades
Low Friction
FEROFORM is compounded with internal lubricants to produce a material with a low coefficient
of friction This low friction is maintained even when lubrication or water is not present.
FEROFROM low friction applies not only under laboratory test conditions, but also under actual operating
conditions. Slick-slip does not occur with FEROFROM bearing even if pumps have been in standby mode
for long periods of time without operating . This can reduce the requirement to prime bearings
before starting a pump. This is critically important for emergency type pumps such as fire pumps, settler
pumps and flood pumps.
Dry Running Capabilities
Pump bearings often need to withstand dry running for short intervals, for example at start up it the pump
inlet becomes blocked. FEROFORM internal lubricants give than a very low friction even when lubrication is not present.
FEROFORM can survive operating canditions where lubrication is delayed or intermittent without damaging bearing.
Many bearing materials operate well under well lubricated situations , but fail if lubrication is not present.

Low wears, Low swell
FEROFORM does not swell or soften in water, where as most synthetic material swell in water. FEROFORM bearings can
be machined accurately to size and maintain these sizes even when immersed.
To compensate for the waterswell and to avoid the risk of seizures, excessive clearances can be maintained, reducing
vibration and shaft run out. Large clearances should be avoided because :
Bearing wear rate increases
Bearing life is shortened
Shatvibration increses, making the shaft less stable.

|
High compression strength
FEROFORM keeps its strength even when wet and does not creep under high loads.
Loads on Vesconite bearings do not result in compression, deformation or compression set. This means that the shaft more stable.
High load capacity Vesconite bearings offer better load capacity than many traditional rubber or elastomer bearings.
|
Low shaft wear
Wear of expensive shafts can be more of wear is especially severe in
dirty operating canditions.
Appropriately designed hard shafts running in FEROFORM bearing exhibit
exceptionally low wear. FEROFORM further reduces shaft wear due to
its lower friction. In particular nylons and many for damage caused to shafts.

Easy to install and remove
FEROFORM bearings are easy to install and remove without the need for expensive equipment. Bearings can be easily
installed on site with a minimum of of effort and equipment, using simple mechanical methods.
FEROFORM does not
corrode and seize in bearing housings, unlike bronze and metal backed bearings which become difficult to remove.
|
|
Easy to machine
FEROFORM can be easily machined on standard metalworking or woodworking equipment.
FEROFORM does not creep, deform or swell and machines easily to desired tolerances.
|
|
Resistant to chemicals
In addition to its excellent performance in water. FEROFORM are resistant to a wide range of chemicals
including acids, organic chemicals, water, solvents, hydrocarbons, oils and fuels.
|
|
Sefety and helth
FEROFORM does not contain any hazardous substances such as asbestos that make using, handling and machining unsafe.
FEROFORM is on exceptionally clean material to machine and possesses no asbestos & dust hazards.
|
|
Low thermal expansion
FEROFORM bearing do not change size significantly as the operating temperature changes, so close clearances can be maintained across
a wide temperature range.
This means that FEROFORM bearings can be designed with minimal running clearances without danger of shaft seizures.
|
|
Environmentatally friendly
Environmentally problems caused by oil or grease lubrication can be avoided. This means simpler pump design and
operation, with great cost savings.
The good chemical resistance of FEROFORM means that a large range of pumped media can be used to lubricate the bearings.
