What is a cam follower/roller follower?
In the past, cam followers and roller followers were mostly used as cam mechanisms in automatic machines and special-purpose machines. However, in recent years, they have also been widely used as guide wheels in machine tools, printing machinery, stamping machinery, transportation devices, conveyor belts, etc. Let’s take a closer look at their respective characteristics.
​
The cam follower\n is a thick outer wheel and a highly rigid shaft bearing with needle rollers called needle rollers embedded inside.
The function of the needle roller is to improve the rotation ability and be able to withstand high-speed rotation. At the same time, the outer wheel is designed to be thicker than ordinary bearings, and can also be used in places where impact loads or double loads occur. \n
Features\n1. With shaft, easy to install
2. Most suitable for places with load bearing
3. Also supports high-speed rotation
​
Usage example\nUsage example 1 (cam mechanism)
The cam and reciprocating follower joint generate rotation → The structural diagram of the linear conversion mechanism and the one-touch clamp is shown. \n
Usage Example 2 (Guide Roller) \nUsed instead of bearings.
As the linear guide moves linearly, the outer wheel rotates.
​
Usage example 3 (Conveying roller)\nUsed as a conveying roller.
The outer wheels rotate to carry luggage.
​
The roller follower\n is a highly rigid bearing with needle-shaped rollers called needle rollers embedded inside. There is no shaft, so it can be designed very compactly. Like the cam follower, it is composed of a thick outer wheel, an inner wheel, and a needle roller. It can be used where loads occur or where high-speed rotation is required. The length of the pin used to secure the roller follower can be specified, so it can be used without concern for the thickness of the mating part.
​
In addition, roller followers are divided into two types: the separable type in which the inner and outer wheels can be separated, and the non-separable type in which the side plate is fixed on the inside. There are also various types with different shapes or structures according to different uses. \n
Features\n1. Best suited for small spaces
2. Load resistance is stronger than rollers
3. Don’t worry about matching plate thickness when installing

Usage Example\nUsage Example 1 (Conveying Roller)\nAs a support for pallets and iron plates.

② Parameters and features
It can be used carefully according to various parameters and combined with the purpose.

③ Users' opinions\nNot only for basic cam mechanisms and transportation purposes, but also recently used as cams and roller followers with polyurethane inside ATMs and printers. When using polyurethane when transporting or dispensing banknotes in machines and printing, high friction can be used to smoothly feed banknotes and paper.

There seem to be various other uses.
