Bearing features (2RS versus 2RSH)

What is the difference between 2RS and 2RSH bearing?

h means they are heavy duty. 6203-2rsh is a bearing with a heavy duty rubber seal on each side. 6203-2rs is a bearing with a standard seal on each side. Depends on your application which one is best for you.

What is 2RSH bearing?

The 2RSH suffix indicates that the bearing has a rubber seal on both sides. If necessary the seals can easily removed if the application requires only 1 seal. The rubber seal protects the ingress of moisture, dust or other dirt. The bearings are filled with a high quality grease and are lubricated for life.

Which bearing is better ZZ or 2RS?

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.

What is the difference between RS and 2r bearings?

RS means seal on one side only and that bearing can only be lubricated from the unsealed side; 2RS would be a double sealed bearing which is factory sealed and lubricated and cannot accept any further lubrication.

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 does ZZ on bearing mean?

ZZ is the code used for sealed bearings, which belongs to the post code in the bearing code. The seal of the bearing indicated by ZZ is a double-sided seal with a dust cover. The material of the seal cover is a steel plate.

What does C mean on a bearing?

internal clearance

The C code of the bearing indicates how much internal clearance the bearing gets in the machine. Your choice is crucial to prevent your bearings from having too much internal clearance. The size of the internal bearing clearance largely determines the operational performance of the bearings.

What is the difference between 2Z and ZZ bearing?

An alternative option is the ZZ Type or ‘2Z’ shielded bearing, which features a metal shield on both sides of its sides. While the ZZ Type cannot be removed once it has been installed, it doesn’t make contact with the inner ring, so there is no impact on the operational speed.

What are the two types of seals used on bearings?

The main difference between the two is that non-contact seals are fixed to the outer ring and do not apply pressure to the inner ring of your bearing. While non-contact bearings do not touch the inner ring, they do feature a thin lip that rests adjacent to it.

What does 2RS mean on a bearing?

Both Sides

Single Rubber Seal. 2RS. Both Sides Rubber Seal. V. Single Non-Contact Seal.

What is better sealed or shielded bearings?

Seals can be either contact or non-contact types. The former offer better protection, but with reduced speed capabilities, whereas the latter have higher speed capabilities and levels of protection superior to shields. Shields have no contact with the inner ring, of the bearing, hence their low torque qualities.

Are Sealed bearings better?

We use sealed so the bearings are protected from road debris and weather, so they spin cleaner and with less friction for longer. Sealed bearings perform as well or better than loose bearings, without the maintenance.

Do sealed bearings need to be greased?

FOR STARTERS, note that most sealed bearings come pre-greased from the factory with a 25%-35% grease fill. This is all the grease the bearings will ever need, because the relubrication interval (explained below) is longer than the expected life of the bearing.

How long do Sealed bearings last?

Lubricant deteriorates over time as a result of ageing, condensation, and separation of the oil and thickener. Therefore, sealed bearings should not be stored for more than three years.
