Although the caster is not very big, but the sparrow is small and complete, it contains a lot of parts. Globe Caster found that many users don't know the specific parts, so let's take a look at it.

1. install the bottom plate

Used to install a flat plate in a horizontal position.

2. Center rivet

Rivets or bolts used to fix rotating devices. Tightening the bolt-type rivet can adjust the looseness caused by rotation and wear. The center rivet is an integral part of the bottom plate.

3. fixed support assembly

It is composed of a fixed bracket, a nut and a wheel axle. Does not include wheels, in-wheel bearings, and shaft sleeves.

4. live support assembly

It is composed of movable bracket, axle and nut. Does not include wheels, in-wheel bearings and bushings. The shaft sleeve is a non-rotating part made of steel, which is sleeved on the outside of the axle, and is used for the rotation of the wheel bearing to fix the wheel in the bracket.

 5.steering bearing

There are several different lamp types, such as:

Single-layer bearing: There is only one layer of steel balls on the large track.

Double-layer bearing: There are double-layer steel balls on two different tracks. Economical bearing: It is composed of steel balls supported by a stamped and formed upper bead plate.

Precision bearings: It is composed of standard industrial bearings.

Knowing this, we must also learn to maintain and maintain each part. We can also replace individual parts if they are damaged, so as to avoid the overall damage of the casters due to ignorance. This will also save the company a lot of expenses.
