What is the main purpose of bearings?
What is the main purpose of bearings?
- To reduce friction and prevent wear and tear of parts (correct)
- To restrict the motion of machine elements
- To increase heat generation in the machinery
- To allow direct metal-to-metal contact
Which type of bearing is capable of handling both radial and thrust loads?
Which type of bearing is capable of handling both radial and thrust loads?
- Deep-groove ball bearings
- Angular contact ball bearings
- Ball bearings (correct)
- Self-aligning ball bearings
What feature distinguishes roller bearings from other types of bearings?
What feature distinguishes roller bearings from other types of bearings?
- Asymmetrical design for unidirectional axial loads
- Prevention of metal-to-metal contact
- Ability to correct axis deflection
- Deep raceway grooves and larger radius circular arcs (correct)
Which type of bearing is rated for unidirectional axial loads and can withstand high radial-axial loads?
Which type of bearing is rated for unidirectional axial loads and can withstand high radial-axial loads?
What is the purpose of self-aligning ball bearings' design with a single spherical raceway on the outer ring?
What is the purpose of self-aligning ball bearings' design with a single spherical raceway on the outer ring?
Roller bearings are widely used due to their versatility and performance, featuring deep raceway grooves, larger radius circular arcs, and nonseparable rings. ANGULAR CONTACT BALL BEARINGS Angular contact ball bearings, asymmetrical and rated for unidirectional axial loads, can withstand high radial-axial loads and reach high speeds. Mounted in preloaded units with rigid or elastic spacers. SELF-ALIGNING BALL BEARINGS Self-aligning bearings feature inner ring with two raceways and outer ring with a single spherical raceway, allowing axis deflection to correct misalignment caused by housing, shaft machining, or installation error.
