What are 6203 ZZ ball bearing used for?

・ It can be used for parts that rotate at high speed with low friction torque and for all applications that require low noise and low vibration.

What is the difference between ZZ and 2RS?

The 2RS are sealed for life bearings i.e. the grease within the bearing cannot get out or contaminants get into the bearing and damage it. The ZZ are just a metal shield to stop larger contaminants damaging the bearing.

What does C3 bearing mean?

Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two rings.

Which bearing is better ZZ or 2RS?

RS provides a better seal but more rolling friction than 2Z. RS - Bearing with rubber seal on one side, one side open. 2 Z / ZZ - Bearing with a metal seal on both sides. Z - Bearing with a metal seal on one side, one side open.

What is the difference between 6203 and 6203 ZZ?

The 6203 is a 17 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6203 Deep Groove Ball Bearings is an open style bearing. The 6203Z ball bearing is a single row raceway and single shielded. The 6203ZZ ball bearing has a single row raceway and it is shielded on each side.

What is HK bearing?

Needle roller bearings use small, cylindrical rollers which are long and narrow. These bearings allow for a large surface area to be in contact with the outer race, and are much more compact than cylindrical rollers.

What is the difference between 6203 and 6203 2RS?

The 6203-2RS ball bearing has two contact rubber seals, one on each side of the ball bearing. The 6203-ZZ bearing has two non-contact metal shields, one on each side of the ball bearing. If your application requires a 6203 ball bearing with only one seal or shield you can simply remove one of the shields or seals.

What are C3 bearings used for?

C3 is designed for hot running environments; engines etc. where the bearing temp could reach 100deg or more. C4 more extreme temperature applications and higher speed environments. C5 the highest clearance bearing available, are extremely loose to start and can knock until at operating speeds and temperature.

What is 2RS bearing?

The 2RS stands for 2 rubber seals. One on each side of the bearing. So the RS denotes only one side is sealed with a rubber seal and the other is exposed and not sealed.
