What are ZZ bearings?
ZZ bearing means that it has metallic shield on both the sides. Generally, it contacts the outer (Stationary) and doesn’t contact inner. To have a trade-off between preventing contamination ingress-ion into the bearing and frictional losses, shields or seals are used.
What is the difference between ZZ and RS bearings?
Type 2 RS is a sealing type with a moulded rubber seal on both sides. Type 2 Z or ZZ is a non-removable, non-contact bearing closure with a metal seal on both sides. This type of seal doesn’t make contact with the inner ring therefore, there would be no impact on the operational speed.
What is a 6200ZZ bearing?
The 6200 is a 10 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6200Z ball bearing is a single row raceway and single shielded. The 6200ZZ ball bearing has a single row raceway and it is shielded on each side.

What is C3 bearing?
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. C3 means the bearing has more clearance than standard.
What is the difference between 2Z and ZZ bearing?
2 RS – Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z. 2 Z / ZZ – Bearing with a metal seal on both sides. Z – Bearing with a metal seal on one side, one side open.
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.
