Crossed roller bearings anti-rust job is very important for bearings performance and service life. Anti-rust work can be divided into two aspects: cleaning and anti-rust.

Cleaning - The First Step of Crossed Roller Bearings Anti-rust Job

Bearing cleaning mainly includes three methods: solvent cleaning methods, chemical treatment cleaning methods, and mechanical cleaning methods. Surface cleaning must be taken based on the nature of the surface of the rust and the conditions at the time, with an appropriate cleaning method. Cleaning is the basic step of crossed roller bearings anti-rust work, only after a thorough cleaning, bearings antirust oil effect can be maximized.
After the surface of the crossed roller bearing is cleaned and dried, it can be blown dry with filtered dry compressed air, or dried with a dryer at 120 ~ 170 ° C, or wiped with clean gauze.

Method for applying antirust oil

1. Soaking method: Small size cross roller bearing can be immersed in anti-rust oil, then coat the surface with anti-rust grease. The thickness of the oil film can be adjusted by controlling the temperature or viscosity of the anti-rust grease.

2. Brush coating method: It is used for outdoor construction equipment or special-shaped products that are not suitable for immersion or spray coating. When coating cross roller bearings, pay attention, not to the amount, too much grease will affect its rotation.

3. Spray method: Some large cross roller bearings cannot be oiled by the immersion method. Generally, filtered compressed air with a pressure of about 0.7Mpa is used to spray. The spray method is suitable for solvent-thinning antirust oil or thin-layer antirust oil, but it must adopt perfect fire prevention and labor protection measures.
