Materials, design and diameter

Materials: 6203 bearings are manufactured from several types of material to meet specific requirements:

• Chrome-plated steel: Offers excellent wear resistance and long service life.
  
  
• Stainless steel (inox): Ideal for corrosive environments, such as the food and pharmaceutical industries.
  
  
• Ceramic: Used for applications requiring high heat resistance and low friction. This type of bearing is also water- and dust-tight, and can be used in environments containing water, such as seawater.water, such as seawater and other corrosive fluids, as well as in specific applications such as bicycle wheels, lawnmowers, and lift pumps.
  
  

Design: 6203 ball bearings are designed with meticulous precision to ensure low friction and smooth performance. Their design enables them to support both radial and axial loads, making them extremely versatile. 6203 2RS bearings, fitted with rubber seals, offer additional protection against dust and water.

Your questions, our answers

What are the dimensions of a 6203 bearing?
The 6203 ball bearing has an internal diameter of 17 mm, an external diameter of 40 mm and a thickness of 12 mm. These dimensions make it a versatile bearing for many applications.

How do I remove a 6203 bearing?
To remove a 6203 bearing, we recommend using a bearing extractor to avoid damaging the shaft or housing. Be sure to apply uniform force to avoid deforming the bearing.

How do I insert a 6203 bearing?
To install a 6203 bearing, make sure the shaft and housing are clean. Use a rubber mallet or suitable insertion tool to apply even pressure to the bearing's outer ring.

How do I lubricate a 6203 bearing?
If the bearing is of the open type, apply a grease or oil suitable for the application. 2RS and ZZ bearings are pre-lubricated at the factory, but may require periodic maintenance if used in extreme conditions.

How to choose a 6203 bearing
Choosing a 6203 bearing depends on operating conditions (load, speed, environment). Consider materials (chrome steel, stainless steel or ceramic), sealing type (2RS, ZZ), and brands renowned for their performance and durability.
