|
Definition
| Easier to replace and can uses shims to tighten. |
|
|
Term
| How are split plain bearings held in place? |
|
Definition
| Held in place with tabs or dowels |
|

Term
| Plain thrust bearings advantages? |
|
Definition
| Stops shaft end movement (Thrust). May require 2 |
|
|
Term
| Different types of plain thrust bearings? |
|
Definition
| Flat (For lighter loads) and Tapered (Heavier loads, Throws oil to outside) |
|
|
Term
| Anti-friction Bearing Advantages? |
|
Definition
| Very little friction, no serrate lube systems, higher rpm, close tolerances, if sealed no lube required. |
|
|
Term
| Types of anti-friction bearings? |

Definition
|
|
Term
| Single row deep groove advantages? Disadvantage? |
|
Definition
| Most common, can handle radial loads. Can handle small axial (can pop apart), requires accurate alignment |
|
|
Term
| Double-row deep groove advantages? |
|
Definition
| Heavier radial load than single row. They are not as common. |
|
|
Term
| What is an advantage of double row angular contact? What is a disadvantage? |
|
Definition
| Heavy radial and two direction axial loads. Slower speed and doesn't like misalignment. |
|
|
Term
| How much of misalignment in self-aligning bearings? |
|
Definition
| Up to 1-1/2 degrees of misalignment. some can handle 2 degrees. |
|
|
Term

Definition
| Cylindrical, spherical, tapered, and needle. |
|
|
Term
| What roller bearings are very common and can handle radial and thrust loads and have 2-1/2 degree misalignment? |
|
Definition
| Single/Double-row spherical roller bearings |
|
|
Term
| What roller bearing can handle Large radial thrust and large one directional axial thrust, typically come in pairs, and doesn't like misalignment? |
|
Definition
|
|
Term
| What are applications of double row tapered roller bearings? |
|
Definition
|
|
Term
| Needle bearings are good for? |
|
Definition
| Radial loads, tight spaces, and doesn't require an inner race but needs a hardened shaft. |
|
|
Term
| What can improper bearing installation cause? |
|
Definition
|
|
Term
| What is the process of installing a bearing? |
|
Definition
| Clean the bearing, heat in oil at 175 deg. , lubricate bearing ID/Od (Light oiling), seat bearing pushing on correct race. |
