What does the suffix mean
The expert's advice
RS, 2RS, 2RSH, 2RS1, RSR, 2RSR, E, EE, LLU, LLB, DU, DDU
These suffixes indicate whether the bearing is equipped with one or two rubber seals. For 123 ball bearings, the number 2 indicates that the bearing is sealed on both sides.
C3, C4
Indicates increased internal clearance. Often referred to as high-speed capability, this indicates that the bearing is designed for high speeds and moderate temperatures. Caution: A bearing with increased internal clearance will not perform optimally at low speeds. We recommend consulting the technical data sheet for the bearing in question to verify the speed limit.
ZZ, 2Z, ZR, Z
These suffixes indicate whether the bearing is equipped with one or two metal baffles for dust protection. For 123 ball bearings, we mark whether the bearing is sealed on both sides with ZZ seals.
TN9, TVH, TVP, G15
These suffixes indicate that the cage that keeps the balls spaced apart in the bearing is made of polymer material, usually glass fiber reinforced polyamide.
ABEC
The ABEC standard is used to classify bearings based on their machining tolerances. However, it is often criticized for not taking into account certain critical technologies that ensure a bearing's functionality, efficiency, and service life. Therefore, 123Kugellager does not use this standard.
BHT / VT
This suffix indicates that the bearing is designed for very high operating temperatures. The exact temperature is usually indicated after this suffix. Caution: These bearings are not suitable for all applications and require high temperatures to ensure optimal service life.
