Bearings 3 Flashcards
A bearing with a greater to 6:1 height to thickness ratio is known as?
Needle bearing
What kind of contact do cylindrical rollers make?
Line contact
4 types of roller bearings

What are speed limiting factors?
Roller length: roller diameter ratio
Grade of precision
Type of cage
Type of lube
Housing accuracy
Heat dissipation of mounting assembly
The steeper the pitch is in a tapered roller the more BLANK it can take
Thrust
More shallow angles on tapered rollers make them better for?
Higher speeds
Spherical bearings are best for situations you may run into?

Needle bearings can typically take higher or lower loads?
Higher load capacity
A tapered roller is usually composed of?
