| Feature | - It can bear large load in vertical direction - ±0.05mm can be selected as the minimum tolerance of length specification, which ensures 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
① Fastening method of hex 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.
② Anti-rust specification selection and maintenance.
If there are requirements for anti-corrosion performance, select products made of stainless steel (austenitic stainless steel).
When carbon steel material with weak anti-corrosion performance is selected, it is recommended to store it in a constant-temperature and dry environment, and regularly apply anti-corrosion oil for maintenance.
