What does RS mean on a bearing?
|Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z.
|Bearing with rubber seal on one side, one side open.
|2 Z / ZZ
|Bearing with a metal seal on both sides.
|Bearing with a metal seal on one side, one side open.
Is 6202 ZZ the same as 6202 2RS?
The 6202-2RS and 6202-ZZ is a 15mm ball bearing that is found in many applications. The 6202-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The 6202-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing.
What is meaning of 2RS in bearing?
2 rubber seals
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. The rubber seal is simply a rubber coating placed over a metal cover to assist in preventing contaminates from entering the bearing.
What is the difference between 2RS and ZZ bearings?
What is the difference between 2RS and ZZ bearings? 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.
How do you calculate bearing size?
How Bearings Are Sized. Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches.
What is the difference between 2RS and 2RZ bearings?
What’s the difference between 2Z and 2RZ bearings? 2Z bearings are fitted with two metal dust shields at either end to keep out dirt and other contaminants. 2RZ bearings are like 2Z bearings, but also have two low-friction seals.
What does LLB mean on a bearing?
LLB = light contact, dual lip, nitrile rubber, steel insert. LLU = full contact, dual lip, nitrile rubber, steel insert.
What is C3 in SKF bearing?
The C3 in the product name means that this bearing has a higher (internal) clearance than normal. The C3 clearance is most frequently used for this type of bearings. The extra internal clearance allows expansion due to high speeds or temperatures. About SKF.
