Unpowered roller It is a cylindrical component which is pushed or changed by external force manually. It is a kind of roller conveyor and the main accessory of conveying equipment. The main function of unpowered drum is to transfer goods by pushing goods manually.
The unpowered drum is composed of the following parts:
(1) Generally, it is made of round tube. Commonly used steel pipe, plastic pipe, high precision and high strength can be made of round steel;
(2) Inner shaft: generally made of round steel. Cold drawn round steel can be used for small diameter, and turning can be used for large diameter and high precision;
(3) End cover: generally made of carbon steel. The small diameter and small load can be processed by punching, while the larger diameter or larger load capacity can be processed by turning;
(4) Bearing: select the appropriate standard bearing according to the cylinder and end cover.
Unpowered roller

The drum is made according to its outer pipe material, pipe diameter, axis diameter, axis material, wall thickness and size calculation method. It is generally divided into two types: one is the non power inner tooth axial conveyor free roller made of yellow PP material, and the other is the non power inner tooth axial conveyor roller made of metal as the material Machine free roller.
The unpowered drum needs external drive.
Structure: special steel bearing seat, semi precision bearing features: durable, flexible rotation, low price
Application: suitable for all kinds of light and medium roller conveyor
Applicable place: suitable for the indoor definition of factory, warehouse and logistics center. The cylindrical component that drives the conveyor belt manually or changes its running direction is a kind of drum and the main accessory of conveying equipment.
Installation mode of unpowered roller

Overview of unpowered drum:
The main function of the unpowered drum is to transport goods by pushing goods manually.
The structural unpowered roller is composed of the following parts: 　　
1. The cylinder body is generally made of round pipe. Commonly used steel pipe, plastic pipe, high precision and high strength can be made of round steel
2. The inner shaft is generally made of round steel. Cold drawn round steel can be used for small diameter, and turning can be used for large diameter and high precision
3. The end cover is generally made of carbon steel. The small diameter and small load can be processed by punching, while the larger diameter or larger load capacity can be processed by turning
4. The bearing can be selected according to the cylinder and end cover.

Structure of unpowered drum
Classification:
It can be divided into the following types according to the different materials of cylinder: 　　
1. Carbon steel drum, that is, the cylinder body is processed with carbon steel pipe
2. The plastic cylinder body is processed with a plastic drum
It can be divided into the following types according to the surface treatment methods of cylinder: 　　
1. Electroplate roller namely roller surface electroplate, common have zinc plating, also can plating chromium, nickel, etc Roller accessories

2. The surface of the roller can be sprayed with plastic powder, which can also be treated by spray painting
3. Rubber coated roller, that is, the surface of the drum is covered with rubber of various colors. The surface of the drum is soft and reduces the wear of goods.

According to the different installation methods of the inner shaft, it can be divided into several types: 　　
1. External thread fastening
2. Internal thread fastening
3. Flat tenon type clamping
4. Round shaft pin type;
5. Spring type
