Yes, the steel chain needs lubrication. Proper lubrication can maintain the cleanliness of the chain, extend its service life, and prevent rust and corrosion. Suitable lubricating oil or grease can be selected based on the specific usage environment and temperature of the chain. For example, at low speeds, mechanical oil can be chosen to lubricate the chain. Low speed chains used on heavy equipment require the use of more viscous lubricating oil or grease.
In addition to lubricating oil or grease, spray lubricant can also be used to lubricate the chain. Spray lubricant can be evenly sprayed on the surface of the chain to form a protective film to reduce friction and wear.

When lubricating the steel chain, the following points need to be noted:
Ensure that the surface of the chain is clean and free of dust, sand, and other impurities.
Choose a suitable lubricant and follow the instructions for use.
Regularly clean and replace lubricants to ensure the long-term use of the chain.
During use, pay attention to observing the tension of the chain and the wear of the sprocket, and make timely adjustments and replacements.
In short, appropriate lubrication can ensure the normal operation and service life of the steel chain, while also improving the working efficiency and safety of the equipment. Therefore, when using steel chains, it is important to regularly lubricate them.
