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.

These ball bearings are made of high quality Stainless Steel and are pre-lubricated with grease from the factory and are available in both RS (Rubber Seals) and ZZ (Stainless Steel Shields) configurations. The SS6207-2RS and SS6207-ZZ is a 35mm bore ball bearing that is found in many applications. The SS6207-2RS ball bearing has two contact rubber seals, one on each side of the ball bearing. The SS6207-ZZ bearing has two non-contact Stainless Steel shields, one on each side of the ball bearing. If your application requires a SS6207 ball bearing with only one seal or shield you can simply remove one of the shields or seals. This 35mm bore ball bearing is a high quality product and can operate efficiently in many demanding applications.

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.

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.

The Deep Groove Ball Bearing, known as 6003-2RS-ZEN ZEN, has an inner diameter of 17 mm, an outer diameter of 35 mm and a thickness of 10 mm.

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.

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".

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".

The Deep Groove Ball Bearing, known as 6003-2RS-ZEN ZEN, has an inner diameter of 17 mm, an outer diameter of 35 mm and a thickness of 10 mm.

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.

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.
