What does the suffix mean?

RS, 2RS, 2RSH, 2RS1, RSR, 2RSR, E, EE, LLU, LLB, DU, DDU

These suffixes mean with 1 or 2 rubber seals. At 123Roulement we use the number 2 to indicate that the bearing is sealed on both sides.

C3, C4

Means increased internal clearance. Often referred to as high speed, this means that the bearing is designed for high rotational speeds and moderately high temperatures. PLEASE NOTE: a bearing with increased inner clearance does not work optimally at low speeds. Consult the technical data sheet of the bearing you are looking for to know the maximum rotation speed.

ZZ, 2Z, ZR, Z

These suffixes mean with 1 or 2 plate shields, for dust tightness. At 123Roulement we indicate whether the bearing is sealed on 2 sides with ZZ.

TN9, TVH, TVP, G15

These suffixes indicate that the cage (the part of the bearing that keeps the balls apart) is made of polymer material. Usually made of glass fiber reinforced polyamide.

ABEC

The ABEC standard is used to classify bearings according to their machining tolerance. This standard is regularly questioned because it does not include certain technologies that are important to ensure correct operation, both in terms of efficiency and the service life of a bearing.

123Roulement therefore makes little use of this standard.

BHT/VT

This suffix indicates that the bearing is designed for very high operating temperatures. In general, the temperature is indicated after this suffix.

Note that these bearings are not suitable for all applications and require high temperatures for optimal service life.

How do I know if my bearing is stainless steel?

A stainless steel bearing is generally magnetizable because it is made of AISI 420 stainless steel, which is harder and more impact resistant than standard stainless steel (AISI 304).

To check if your bearing is stainless steel, simply read the reference engraved on the side of the bearing. This reference must start with the prefix S, which means Stainless Steel.

What is the difference between all the choices I have for my reference (example 6205-2RS)?

Some bearings are available with more or less important variants (large or smaller inner clearance, special grease, very high temperature, etc.). These variants are systematically indicated by prefixes and suffixes in the part number.

For example, the suffix 2RS means that the bearing is splash-proof, thanks to a sealing flange on both sides of the bearing.

The suffix C3 means that the bearing has a larger internal clearance and requires a higher operating temperature or a higher rotational speed.
