Bearings

Question 1

Define a bearing race

Answer 1

A ring with a grove for rolling elements to roll in. Usually a bearing consists of an inner and outer race

Question 2

Define a bearing cage

Answer 2

A container that holds balls between the inner and outer race

Question 3

Define ball bearings

Answer 3

Most common bearing that can support radial and thrust loads relatively well. Typically only used for lower load applications

Question 4

Define roller bearings

Answer 4

Bearings with cylinders as the rolling element. Supports high radial loads since the cylinders distribute pressure to a line (rather than a point on a ball). Cannot handle much thrust loading since the face of the cylinder is flat.

Question 5

Define needle bearings

Answer 5

A special type of roller bearing that has a thin radial profile so it can fit into tight places

Question 6

Define tapered roller bearings

Answer 6

A type of roller bearing that can withstand high radial and thrust loads since the rolling element is tapered cylinders. Used in car hubs.

Question 7

Define thrust bearings

Answer 7

A type of ball bearing designed to handle high thrust load but cannot handle much radial load. Used in barstools and turntables

Question 8

Define linear bearings

Answer 8

Provides low friction for heavy loads in a linear motion along a rail

Question 9

Define sleeve bearings

Answer 9

A type of linear bearing that slides over rods or shafts instead of rails
