What's the difference between a motor, a shaft tile, and a bearing's?

Bearings are rolling bearings (commonly called ball bearings). And the shaft tile is a sliding bearing, there is no ball, the shaft rotates directly in the shaft tile. A shaft tile is the part that supports the journal, usually made of bronze and coated internally with a liner.

Expanded Information

Shaft tile material is usually softer, the inner cylindrical surface should not be processed by grinding method, can be used boring, diamond boring, scraping or grinding method. Grinding should not be used with the shaft diameter with the method of research, and should use a special, size and the size of the shaft tile hole the same research rod. Scraping is mostly used for part of the tile bearing, with a wide blade scraper machine scraping. Hand scraping, scraping marks should be shallow.

Thick-walled shingles can be cast, in order to improve the friction performance, can be poured on the inner surface of the shingles a layer of bearing alloy (known as bearing lining). In order to make the bearing alloy and good adherence to the shingle, often in the shingle on the inner surface of the various forms of mortise and tenon, concave groove or thread. Thin-walled shingles can be produced in large quantities by continuous rolling of bimetallic plates and other processes.

Rolling bearings according to the direction of the load it can withstand or nominal contact angle is divided into centripetal bearings and thrust bearings. Among them, radial contact bearings for nominal contact angle of 0 centripetal bearings, centripetal angular contact bearings for nominal contact angle greater than 0 to 45 centripetal bearings. Axial contact bearings are thrust bearings with a nominal contact angle of 90, and thrust angular contact bearings are thrust bearings with a nominal contact angle greater than 45 but less than 90.

By the shape of the rolling body can be divided into ball bearings and roller bearings. Roller bearings according to roller type is divided into: cylindrical roller bearings, needle roller bearings, tapered roller bearings and spherical roller bearings.
