iglide® T500
The High Tech Problem Solver
iglide T500 is a unique bearing material that combines three specific characteristics:
Temperature resistance, high load capacity and universal chemical resistance.
The compound comprises a high temperature resistant thermoplastic alloy, supported by a network of special fibers
and permeated by solid lubricants . The solid lubricants were tested for their temperature compatibility and inertness
to chemicals.
Resistance
Wall thickness of iglide T500 bearings range between .03 in. and .1 in. depending on diameter. The bearings feature
exceptional heat conducting properties for plastic materials.
iglide T500 has become the ideal bearing selection in chemical and oven equipment, semi conductor production, textile
machines and heavy machinery manufacturing industries.
Special Characteristics of iglide T500
Temperature resistant from -149°F to +485°F for continuous operation
Can be loaded to 21,759 psi
Universal chemical resistant
Maintenance free during dry operation
High resistance to radiation
Space saving
Designed for rotating, oscillating and linear operation
P x V Values
iglide T500 reaches P x V values up to 100,000 (psi x fpm) during dry operation. High levels of temperature resistance
and heat conducting capability permit iglide T500 to achieve higher speeds than would be possible with other iglide
bearings. With linear motion surface speeds up to 975 fpm are possible.
iglide T500 offers long life with oscillating movements at high load levels, or at high frequency with low load
levels.
iglide T500 can be lubricated with grease, oil, water and other fluids, including acidic fluids. Permanent lubrication
results in reduced friction values and increased P x V values.
iglide T500 is designed for applications which require high levels of load capacity.

Compressive Strength
Illustration X assumes the maximum P x V values at room temperatures. One of the significant advantages of iglide
T500 is its excellent load capacity even at higher temperatures.
At 485°F, it is still possible to reach a static unit pressure of up to 4350 psi. Good abrasion resistance
is still maintained at this level. At room temperature, load resistance of iglide T500 is very similar to that
of steel .
Coefficients of friction
iglide T500 bearings reach friction values between 0.09 and 0.20 during dry operation with steel. At high load
levels and low speeds, friction values are low, while the reverse combination produces high friction values.
Additional lubrication reduces the coefficient of friction. (Table X). In the case of chemical pumps, for example,
media such as acidic fluids, have a lubricating effect.
Static and dynamic friction values are almost identical. iglide T500 has excellent “start up” properties.
This includes bearings which are activated only once per year.
The friction value at the beginning of the “start up” phase is relatively high, yet continuously decreases. Installation
lubrication will facilitate initial start-up.

A significant advantage of iglide T500, compared to other high temperature resistant plastic materials, is that
it maintains it’s consistency and excellent wear resistance, even at very high temperatures. iglide T500 has high
dynamic load capacity during continuous operation at temperatures ranging between 390°F and 485°F.
Performance
At room temperatures, iglide T500 is no more wear resistant than iglide G300. Demanding applications emphasize
the high performance of iglide T500.
The following applications describe some of the significant advantages of iglide T500.
In the chemically aggressive field of semi-conductor production, metallic bearings were exchanged - on a regular
basis - every 2 to 3 weeks with iglide T500. The bearing remained in good functioning condition for many years.
In the area of production machines for starter batteries, acidity problems have been solved with iglide T500.
During applications involving high levels of radial pressures (in excess of 8700 psi) and low speeds, iglide
T500 bearings produced double the life compared to coated or lubricated metallic bearings.
Electrical Properties
As with all iglide materials, iglide T500 has electrically isolating properties, yet at a lower intensity level.
The specific resistance is 1.4 x 105 OHM cm.
Radiation Resistance
iglide T500 features the highest level of resistance to gamma rays within the entire iglide range.
iglide T500 is extremely resistant to intense gamma rays and is capable of withstanding a dose of 100 M Rad without
measurable reduction of its own properties. Without any difficulty, the material withstands an alpha or beta dose
of 10,000 M Rad.
Vacuum
iglide T500 can be used without limitation in a vacuum.
Weather Resistance
iglide T500 is well suited for outdoor use and features permanent resistance to UV radiation, corrosion and the
ozone.
Chemical Resistance
iglide T500 bearings are resistant against nearly all known chemicals. Corrosion occurs under the influence of
concentrated nitric acid solution and sulphuric acid with acid contents in excess of 65%.
Please refer to the list of chemicals for details.
iglide T500 bearings retain an unusually low amount of humidity. The bearings can be used under water without any
change in their fitted conditions.
Shaft Materials
As with other iglide materials, iglide T500 functions extremely well in conjunction with hardened steel to 50 RC,
with a surface finish Ra = 16 - 32rms.
Stainless steel is a frequent requirement in the area of chemical equipment manufacture. iglide T500 has performed
very well with special steels V2A and V4A, for example.
Please refer to our technical sales engineers for details.
If iglide T500 is exposed to high dynamic loads within the temperature range of 390°F - 480°F, it is
recommended to apply and adhesive to the bearing OD prior to pressing it into the housing.
