Bearing Lube Flashcards
What are 2 different types of lubricant we use?
Oil
Grease
What are 2 different types of oils and greases?
Petroleum based
Synthetic
A type of lube used for high heat low speed applications
Dry lube
Oil is typically used for what type of speeds?
High-speed application
What is more easily retained in a housing?
Grease
A type of bearing that provide low friction motion on one plane
Linear bearing
A seal that fits tight around the shaft(typically creates more friction)
Contact seal
Seals preform what 2 basic functions?
Keep lubrication in and contamination out
Type of fitments
Interference fit, tapered fit, slip fit
Type of slip fit retention methods
Set screw, cam lock
A type of mounted bearing housing typically mounted perpendicular to the shaft(horizontal)
Pillow block
A type of mounted bearing housing typically mounted vertically
Flange cartridge block
2 types of pillow blocks
Split and solid
These types of bearing assemblies are used to adjust center distance between shafts or where belt tightening is required.
Take up unit
A type of bearing used to compensate for misalignment, commonly used in linkages.
Rod end bearing
A type of bearing in a shaft head configuration that can accommodate symmetrical and elliptical motion
Cam-type and load following bearings
A lubricant base that will not mix with water(hydrophobic)
Lithium
A couple of examples of dry lube
Graphite
Teflon
A looser type of seal that is lower friction and better for high speed applications
Non contact seal
Advantage of synthetic lube?
Higher boiling point than petroleum based
Advantage of petroleum lube?
Cheaper cost
