Open bearings do not have seals or shields, this allows oil or grease to flow through the bearing for lubrication purposes. They are generally used in gearboxes or areas that are not subject to dust or moisture.
C3 tells us that the balls have room for expansion if needed between the races of the bearing. They are generally used on electric motors where a cold start up my cause the balls to heat up quickly and expand, which on a standard clearance bearing would cause premature failure.
Our popular metric ball bearings are available in Standard, SKF or FAG.
Please note this bearing has no seals or shields with a C3 clearance with a C3 clearance
Please see below information for reference:
2RS, 2RS1, 2RSH, DDU= 2 Rubber seals
RS =1 Rubber seals
ZZ, 2ZR, 2Z= 2 Metal Shields
Z =1 Metal Shields
C3 = Higher Internal Clearance
NR = Circlip Groove on outer
***Please note that if FAG is out of stock we will supply SKF as an alternative***
