If there are requirements for rust prevention, give priority to products made of stainless steel or those with surface treatment of electroless nickel plating. For rust prevention methods, please click

Rust Prevention Methods.

Products made of general structural steel or carbon steel are coated with anti-rust oil.

The female thread may not be surface treated.

Due to female thread processing, the D part of the female thread may sometimes be slightly raised.

There may be grinding gloss marks near the wrench slot on products without surface treatment.

Feature 4: Products with surface treatment (electroless nickel plating) and material (stainless steel) for good anti-rust performance are widely used in precision equipment and dust-free environment.
Feature 5: with the main functions of connection, fastening, support and separation, it is often used in mechanisms with various frames as a connection and support component.

Usage Method

Intended Use	Support and Fixation	Fastening and Connection	Separation
Usage Method Diagram
Feature	- Can withstand large loads in the vertical direction - Minimum length tolerance specification selectable to ±0.05 mm, ensuring the stability of the mechanism	- Simple and aesthetic connection	- Connected to the baffle to effectively block the mechanism in operation and prevent interference - Easy to fasten and install in narrow spaces

Precautions

①Fastening method of post
The post is generally fastened by torque method. For bolts, fasten them within the range of fastening torque, otherwise excessive torque will cause thread fracture.
②Anti-rust specification selection and maintenance.
If there are requirements for anti-corrosion performance, select products with surface treatment of electroless nickel plating or those made of stainless steel (stainless steel) when choosing general structural steel products.
General structural steel posts without surface treatment are recommended to be stored in a constant-temperature and dry environment, and regularly applied with anti-rust oil for maintenance.

Example of Use

Factory Direct Selling MISUMI Round Posts Tapped and Threaded Type

Equipment name: Pull-in conveyor
Function description:
The pull-in conveyor is a space-saving type non-driving conveyor
Function: With the collaboration of the pull-in mechanism and the roller bar, the conveying function can be achieved without driving equipment, and the detection is performed with a proximity sensor, thus improving the operation efficiency of the equipment, suitable for narrow spaces with no room at the bottom and difficult for hands to reach in.
Function of round post in the mechanism
①Round post is used as a fastening connector in the mechanism to support the weight of all workpieces on the upper part and increase the stability of the mechanism.
②Because the mechanism is often used in narrow space, the fastening method of round post is very simple and convenient, thus facilitating the installation and maintenance of equipment.
