What is 2Z in bearing?
The 2Z suffix indicates that the bearing has a steel seal on both sides. The bearings are filled with a high-quality grease and are lubricated for life. Internal play. The C3 in the product name means that this bearing has a higher (internal) clearance than normal.

What does 2RZ mean on a bearing?
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.
Which bearing is better ZZ or 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 is the meaning of C3 in bearing?
has room for expansion
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.
How do you read a bearing code?
The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D). The last two digits of the basic designation identify the size code of the bearing bore. The size code multiplied by 5 gives the bore diameter (d) in mm.
Is Llu the same as 2RS?
Nope, 2rs is standard rubber seals. LLB is two light contact lips in a groove, LLU is two firm contact lips in a groove. SRS is a snap ring on top of the seal.
What is the difference between 6203 and 6203 2rs?
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.
What is a 6203 2rs bearing?
Deep groove ball bearing with seals. Single row deep groove ball bearings with seals on one or both sides are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds.

What is C3 and C4 in bearing?
The “C” rating stands for the clearance between the rings and rollers of the bearing. The greater the temperature variations the higher the C rating would be needed. C3 or C4 won’t make much difference for a high rpm engine. However C4 would be preferable for a high-load engine.
What is C2 clearance?
C2, or controlled access protection, is the lowest that offers viable security. For C2 certification, a system must. Have good documentation at both the user and administration level and have documentation on security testing. Authenticate all users as unique individuals.
What do numbers mean on bearings?
What is difference between LLU and LLB bearings?
For our purposes, LLU is a full contact seal system, while LLB is non-contact. Some hubs (White Industries is one) come with “2RS” seals, which literally means 2 Rubber Seals.
What does LLB stand for in bearings?
On most other bearings 2RS means that the seal is made from rubber and has one sealing lip rubbing on any flat part of the inner race. Enduro’s seals are usually either LLU (usually the MAX type bearings) or LLB (better for hubs).

What is C3 on 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.
What does C mean on a bearing?
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.
