The Deep Groove Ball Bearing, known as 608-2RS-W103-FAG FAG, has an inner diameter of 8 mm, an outer diameter of 22 mm and a thickness of 10.3 mm.

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. CAUTION: a bearing with increased internal clearance will not operate optimally at low speeds. Please refer to the data sheet for the bearing you are looking for to find out its rotation speed limit.

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

2Z - Gap seals on both sides. These bearings are greased using a high-quality grease, lubricated for life and suitable for high speeds2HRS - Lip seals on both sides made from nitrile butadiene rubber. These bearings have an improved sealing function and retention in the outer ring. They are greased using a high-quality grease, lubricated for life and suitable for moderate speeds2BRS - Non-contact seals on both sides. Their friction level is as low as with the gap seals. In addition, they offer better protection against the ingress of dust and the escape of lubricant2RSR - Lip seals on both sides made from nitrile butadiene rubber NBR and are suitable for moderate speedsC - Modified internal construction in Generation C

FAG from Schaeffler deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain. They are available in single and double row designs and in open and sealed variants. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields.

Open bearings are suitable for high speeds. Due to the manufacturing process, they have turned recesses for sealing washers and sealing shields.

Open bearings are suitable for high speeds. Due to the manufacturing process, they have turned recesses for sealing washers and sealing shields.

Some bearings are available with more or less important variants (high or low internal 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 increased internal clearance, and will require a higher operating temperature, or a higher rotation speed.

The Deep Groove Ball Bearing, known as 608-2RS-W103-FAG FAG, has an inner diameter of 8 mm, an outer diameter of 22 mm and a thickness of 10.3 mm.

These suffixes mean "with 1 or 2 sheet metal deflectors", for dust-tightness. At 123Roulement, we specify whether the bearing is sealed on 2 sides with "ZZ".

A stainless steel bearing is generally magnetizable, as it is made from AISI 420 stainless steel, which is harder and more shock-resistant than standard stainless steel (AISI 304).To check whether your bearing is made of stainless steel, simply read the reference engraved on the side of the bearing. This reference should begin with the prefix "S" meaning "Stainless Steel".

The ABEC standard is used to classify bearings according to their machining tolerance. This standard is regularly called into question because it does not include certain technologies that are important for guaranteeing proper operation, both in terms of efficiency and bearing life.123Roulement therefore makes little use of this standard.

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

This suffix indicates that the bearing is designed for very high operating temperatures. In general, the temperature is indicated after this suffix.Beware, these bearings are not suitable for all applications, and will require a high temperature for optimum service life.
