Currently approved supplier for:

micropoly composition
MicroPoly Composition
  • MicroPoly is a microporous polymer lubricant. It is a mixture of:
    • Plastics
    • Oil
    • Other additives
  • MicroPoly is over 50% oil by weight.
micropoly is a sponge
MicroPoly is a “Sponge.”
  • When friction or heat is applied, the
  • “sponge” weeps oil to the surface.
  • This provides constant, consistent
  • lubrication as the bearing rotates.
  • When the bearing is at rest, oil can be
  • reabsorbed by the MicroPoly.
micropoly applications
MicroPoly Applications
  • Ball and roller bearings
  • Linear bearings
  • Ball screws
  • Roller chain lubrication
  • Bushings
  • Wheel flanges

All Types of Bearings
filled bearings
MicroPoly-filling bearings does not alter the dimensional tolerances of the bearing in any way. As you can see below in the tapered roller bearings, the MicroPoly simply fills the spaces between the rollers and the cage.Filled Bearings
when should you use micropoly
When should you use MicroPoly?
  • When bearings are failing due to:
    • solid contamination
    • liquid contamination
    • lack of lubrication
    • over lubrication
  • When conventional lubrication contaminates the end product or causes safety hazards.
  • When labor or down time costs are substantial.
benefits of micropoly lubrication
Benefits of MicroPoly Lubrication
  • Reduces costs associated with labor or down time due to bearing failure
  • Reduces contamination
  • Provides a maintenance-free bearing
  • Extends bearing life
  • Improves housekeeping by eliminating the dripping of grease and oil
benefits cont
Benefits, cont.
  • Reduces scrap rate of parts caused by lubrication dripping onto parts
  • Provides lubrication to difficult to reach applications
  • In most cases, automatic lubrication systems can be eliminated
micropoly vs conventional lubrication
MicroPoly vs. Conventional Lubrication
  • Grease - about 35% oil suspended in a thickener
  • MPL - over 50% oil
  • Grease - bearing is filled 1/3 to 1/2 full. Overfilling can cause churning.
  • MPL - bearing is filled 100%. More oil is available for lubrication. Due to solid structure, there is no churning.
  • Temperature Limitations – see Cross Reference Guide
  • No direct contact with
    • Acids
    • Strong detergents
  • Speed Limitations

All new applications should be reviewed

with PhyMet personnel.

Original Equipment Manufacturers

Application: Steering columns in trucks

Bearing Type: Tapered roller thrust bearing

Problem: Due to severe road conditions dirt,

water, and road salt contaminated

the bearings. Warranty

requirements were not being met.


Over 150,000 of these bearings have been

filled over 8 years, with no failures reported.

Warranty requirements are being met.

automotive industry
Automotive Industry

Application: Towmotors, front wheel spindles

Bearing Type: Tapered roller bearings

Conditions: Heavy load. Bearing life 3 - 12



Bearing life extended to 3.5 years. The

automobile company saved $337,134.

power generating industry
Power Generating Industry

Application: Coal pulverizer grinding wheel

Bearing Type: Tapered roller bearings

Problem: Coal dust caused bearing seizure,

resulting in the dust igniting.

Bearing life 9 months.


Bearing life extended to 10 years. Fires

were eliminated. The company saves

$250,000 per year.

food processing industry
Food Processing Industry

Application: Feather picker, chicken processing

Bearing Type: Single row ball bearing

Problem: Washdown of the bearings with

water and detergents causes

premature bearing failure. Bearing

life 3-4 weeks.


So far bearings have lasted 9 weeks and are

still running. Estimated savings $170,000.

Food Processing Industry

Application: Potato chip sizer

Bearing Type: UC205-16 Ball insert bearing

Problem: Salt and other seasonings

contaminated the bearings. Bearing

life was 6-8 weeks. Downtime costs

are $25,000 per hour.


Bearing life has been extended to 18 months.

Estimated cost savings over a 6 year period:

Metal Processing Industry

Application: SealMaster SFT 35E – 2 7/16” bore

Bearing Type: Housed ball bearing, 2-bolt flange

Problem: Buried in sulfur-contaminated sand.

Bearing was contained with an end

cap. Temperature 110°F. Bearing

life 6 months.


Bearing life is now 12 months and the greasing

schedule has been reduced. End cap was


earth moving industry
Earth Moving Industry

Application: Trenching Equipment

Bearing Type: Guide wheels and idler wheels,

22308 spherical roller bearing (axle

bearing), FYRP 2 ½” roller bearing

Problem: Trenchers run in dusty, dirty, muddy

conditions. Dirt and mud are pulled

up into the bearings.


Life of the idler wheels and axle bearings was

extended from one month to one year. Life of the

FYRP bearing was extended from 2 months to

2 years.
