Radial bearings are typically used in applications such as electric motors, pumps, and compressors, while thrust bearings are used in applications such as turbines, gearboxes, and automotive transmissions

7.What is the recommended maintenance schedule for 6221-Z KOYO bearings?

The recommended maintenance schedule for bearings depends on the type of bearing and the application
Generally, bearings should be inspected and lubricated at least once a year, or more frequently if the application is in a harsh environment
Additionally, bearings should be replaced when they show signs of wear or damage

8.How does a 6221-Z KOYO bearings function?

We adhere to the principle of integrity and transparency, and establish long -term relationships with partners, and we attach great importance to this detail
A bearing is a mechanical device that is used to reduce friction between two moving parts
It works by allowing the parts to move relative to each other while reducing the amount of friction between them
Bearings are typically composed of two parts: an inner race and an outer race
The inner race is typically made of a harder material than the outer race, and it is designed to rotate around the outer race
The inner race is typically lined with a lubricant, such as oil or grease, which helps to reduce friction and wear
The outer race is typically made of a softer material than the inner race, and it is designed to remain stationary while the inner race rotates
