Maintenance-free bearings are special rolling bearings designed to work stably for a long time without regular maintenance. This kind of bearing adopts special maintenance-free technology, so that there is no need to refuel the bearing during use, thereby avoiding pollution caused by continuous refu

How to maintain bearings coated with rust inhibitors1. Foaming method: Some small and medium-sized objects choose the foaming method in the vegetable oil anti-rust treatment, so that their surfaces adhere to the vegetable oil anti-rust layer. The thickness of the oil film can be determined based on

The main difference between maintenance-free bearings and normal bearings is that maintenance-free bearings do not require regular maintenance, while normal bearings usually require regular maintenance and repairs. This is because maintenance-free bearings use some new materials and technologies to

The harm of moisture is reflected in two aspects: direct damage to metal surfaces, and damage to lubricating oil/grease, which indirectly leads to bearing damage.Moisture will cause corrosion on metal surfaces. For lubricating oils and greases, moisture will cause the base oil in the oil to oxidize
