Compared with ball bearings, sleeve bearings typically exhibit what characteristic?

• A. Higher Coefficient of Friction
• B. Higher Speed Capability
• C. Lower Load Capacity
• D. Less Wear Tendency

Answer: (A)

Plain (sleeve) bearings work with sliding contact between the shaft and the bearing surface. That sliding contact inherently causes more resistance to motion than the rolling contact used in ball bearings, where small balls or rollers carry the load. Because of this sliding nature, sleeve bearings typically have a higher coefficient of friction than ball bearings. Proper lubrication can reduce friction, but the fundamental difference remains: rolling elements in ball bearings lower friction and enable higher speeds, whereas plain bearings rely on sliding, which is inherently less efficient. The other statements don’t fit as generally: sleeve bearings aren’t inherently better for high speed, they don’t necessarily have lower load capacity, and wear tendency depends on lubrication and conditions rather than being inherently less or more.
