We offer several varieties of bearings:
Lubring
Lubring
Slideways (a proprietary PTFE /Teflon® formulation) is a
superior bearing material developed specially for machine tool
ways, gibs and other sliding applications. Lubring has identical properties to Turcite® and is widely used
by leading machine tool manufacturers, re-builders and in-plant
personnel to restore existing equipment to like-new precision.
As a sliding bearing material this sheet/tape is unequalled
for providing high compressive strength and load carrying capabilities,
low friction, precise positioning accuracy and minimal wear
– with or without lubrication.
Properties include:
- Extruded billet process – a reduced internal stress
allows Lubring to lay flat for easier handling
- Superior etched surface – promotes easier, more reliable
installation with superior adhesion
- Excellent vibration dampening – dampens cutting tool
vibration from migrating throughout the machine tool
- Increased positional accuracy – lower friction increases
positional accuracy and repeatability on linear ways
- Chemical resistance – resists aggressive coolants
and lubricants
- High wear resistance – ensures long service life
- Low wear in the event of dry operation – protects
mechanical components in cases of poor or failed lubrication
- Impervious to moisture
In
many application situations, to lubricate two moving parts sliding
against each other can represent a tough problem because of
the application nature itself or for cost reasons. It is therefore
essential, in these cases, to use bearings able to operate completely
dry while offering a proper performance level.

Oil Free Polymer Bearings
Oil
Free Bearings provide an ideal solution for extreme operating
conditions. The product offers the best balance in terms of
a low coefficient of friction and wear rate and a low cost.
Further, these bearings can be used in a wide variety of applications.

There
is practically no industrial segment where the typical characteristics
of oil-free bearings cannot be advantageously used. Typical
segments include automotive, textile, fluid handling equipment,
machine tools, packaging machine and packing plants, food and
pharmaceutical machines, besides appliances, office machines
etc.

PTFE piston bands
Poly
Fluoro Piston Bands are designed for hydraulic and pneumatic
equipment. Its unique design prevents equipment seizures which
can arise with other forms of guidance materials. Poly Fluoro
Piston Bands offer extremely low friction and break-away forces.
This material is also resistant to all hydraulic fluids, and
is suitable for temperatures up to 200°C.
The
bearing material is made from PTFE with a 40% Bronze filling
and is specifically designed to support heavy loads. The exceptional
physical properties and PTFE lubricants make the piston bands
suitable for use on rams or pistons in reciprocating applications.

Bridge Bearings
Poly
Fluoro Ltd. has combined its expertise in PTFE skived
sheets with know-how on PTFE bonding techniques to produce high
quality and durable bridge bearings. We have opted to focus
on PTFE bridge bearings – sliding bearings and PTFE-POT
bearings – as these allow us to hone in and capitalise
on our expertise in PTFE processing.
Our bearings usually employ PTFE virgin sheets or PTFE with a 25% glass filling
as this gives us better creep properties than other fillers while not compromising on the coefficient of friction.
Fillers of bronze, carbon and MoS2 are also available. Depending
on customer specifications, we can colour the PTFE sheets with
a variety of pigments including gold, turquoise and green.
Due to our in-house milling, grinding and bonding capabilities,
we are able to provide fully assembled bridge bearings as per
our customer specifications. However, as our core competence
lies in PTFE sheets, we are also able to provide standalone
plates for use in bridge bearings – should our customer
wish to machine and assemble the bearings on-site. This versatility
allows us to cater to both the end-user as well as other bearing
manufacturers.
Poly Fluoro Ltd. also has design capabilities which allow us to study the load and movement requirements of a given bearing and prescribe the right size and materials which would offer optimum performance. The following codes are strictly adhered to for all bearing design and manufacture:
Design - BS 5400
Mild Steel - IS 2062
PTFE - ASTM 4894
Stainless Steel - IS 304
We are equipped with facilities for testing the tensile properties,
deformation properties and shore hardness of our sheets before
we employ them in bridge bearings, as well as the ultimate limit state load of the bearings themselves.

Bushes
PTFE bush bearings offer
dry-running lubrication-free behaviour. Our bushings provide
the step from a simple plastic bushing to a proven and tested,
and thereby predictable and quickly available, machine component.
Solid PTFE bushes give low weight and corrosion resistance,
as well as the freedom from maintenance and lubrication to enable
a solution for almost all applications.
Poly Fluoro offers bushes in PTFE/Teflon® both with virgin
material as well as with a variety of fillers including bronze,
carbon, glass, ceramic, graphite and molybdenum di-sulphide.
