We are a “Plain Bearing”
•Basically this means that we do not use rolling technology like
ball bearings.
•Instead of rolling we are sliding (friction bearings)
•Often times referred to as “Bushings”
What benefit can innovation in polymers
have for plain bearings?
Thermoplasic
polymer
+ Reinforcing
compounds
+ Solid lubricants
= iglide®

Universal and custom solutions
Advantages of Polymers are enhanced
Disadvantages of Polymers minimized or eliminated

Unique Selling Points
* Maintenance-Free
• No lube (messy, bad around food, attracts dirt,
dust, etc.)
• Lifetime Calculation/Online Calculator
• Light - Quiet
• Vibration Dampening
• Good in Abrasive Environments
• Good Chemical Resistance
• Quiet Operation
• Higher Static Load than Bronze/Steel plain
bearings
•
Other types of
Plain Bearings
Sintered Bronze (Oilite)
• Oil-impregnated
bearings
• Most common in US
• Best for high RPM
applications
• In most apps they are
not used correctly
• Need maintenance/oil
What about Bronze?
Sintered-Bronze (Oilite)
• Iglide Advantages:
– Better for linear (no
oil)
– Better for
pivoting/oscillating
– Better for lower speeds
– No lube in dirty
environments, food
applications, etc.
Mention Iglide “R” and “M250” as they are dimensionally interchangeable
DU Bushing (Garlock)
• Metal-backed Teflon
liner
• Very common in
Europe
• Dimensionally similar
to Iglide thin-walled
parts
DU Bushing (Garlock)
• IGUS Benefits:
– Lower Cost
– Better in bad
environments (think
about scratching a
Teflon pan)
– DU has thin liner-if
gone you get metal-tometal contact = bad.
When you see these applications we often recommend our G300 material
The 6 Rules of Iglide:
1. Check application surface pressure, speed,
and temperature
2. Max Pressure x Velocity (P*V value) =
28,571 continuously lube-free
3. Ideal App is low speed <60FPM, with
loads up to 14,500PSI (rotating/pivoting)
4. Use hardened shafts if PSI >725
5. Total travel <6000 miles
6. Clearance of .02”-.04” is acceptable
Extreme Iglide Products
• iglide® Z/T500
• For extreme loads
21,000PSI +
• For high temperatures
• Permanent application
temperature 550F
• Excellent chemical
resistance

We have the very unique capability to calculate lifetime and wear!
Competition: Ball Bearings
Names: THK-Thompson-Hiwinn-IKO-INA-Star-Rextroth
aka. Ball bushings, ball slides, recirculating
ball bearings
Disadvantages:
1. Not suitable for abrasive/harsh environments
(dirt, chemicals, water, washdown, metal shavings)
2. Not good with high static loads
3. Often over engineered for many
applications= Very $$$
4. Loud
5. Must use special, hardened, expensive shafts
Tribocological
Benefits
Competition- plain bearings
Main US competitor is Pacific Bearing
Disadvantages:
1. No lifetime calculations
2. Mostly sold through Distributor
3. More expensive
4. Bad in harsh environments
5. CANNOT REPLACE LINERS
DryLin® - 2 : 1 Rule
The Principle:
fixed bearing
floating bearing

drive
The driving force
must not be
further away from
the fixed bearings
than twice the
distance between
the bearings
