Sliding contact bearings are classified into...

🔍 Key Concepts

• Sliding contact bearings support surfaces that slide over each other with a film of lubrication, not rolling elements. • A journal bearing supports a rotating shaft over its cylindrical (radial) surface. • The other major category is based on whether the bearing primarily resists axial (end) load or radial (side) load.

💭 Think About

• Ask yourself: What type of load does a journal bearing mainly support—radial or axial? • Then think: The question is asking for the other general category of sliding contact bearing. What type of sliding bearing is designed mainly to take axial (end-thrust) loads? • Eliminate any options that clearly describe rolling-element bearings rather than plain sliding surfaces.

✅ Before You Answer

• Check which choices involve rolling elements (like rollers or needles) and recognize those are not sliding contact types. • Confirm that journal bearings are associated with supporting the radial surface of a shaft, so the other main category will be associated with end-thrust loads. • Verify that the correct category name matches a bearing whose main job is to handle axial (end) loads rather than radial loads.
