The Deep Groove Ball Bearing, known as 6002-2Z-C3-GJN-SKF SKF, has an inner diameter of 15 mm, an outer diameter of 32 mm and a thickness of 9 mm.

The code .2RS is a short code for “Two Rubber Seals”. This means that the ball bearings are enclosed and are protected by the rubber seals. They keep the moisture and dirt out of the ball bearing which improves its usage. Click here to see the variants of this bearing.

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 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.

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.

2 – Metal Shielded – This also protects the ball bearings from dust, the metal shields allow the ball bearings to move a lot faster than the rubber seals however the metal shields may not stop moisture getting into the bearing which could cause it to rust.

Single row deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for very high speeds and are robust in operation, requiring little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads, even at high speeds.

3 – Open – The open bearings do not have a protection for the ball bearings, everything can be accessed in an open bearing. These are mainly used if the area that the bearing is being used is enclosed and not exposed. Not having the protective shields on means the bearing can move alot faster and easily.

The Deep Groove Ball Bearing, known as 6002-2Z-C3-GJN-SKF SKF, has an inner diameter of 15 mm, an outer diameter of 32 mm and a thickness of 9 mm.

1 – Rubber Sealed – This protects the ball bearings from dust and anything that may cause the bearing to rust or break. The rubber seals still allow grease to get to the ball bearings but nothing else can access them, This means the bearing won’t be prone to rust or breakages.

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 Deep Groove Ball Bearing, known as 6002-2Z-C3-GJN-SKF SKF, has an inner diameter of 15 mm, an outer diameter of 32 mm and a thickness of 9 mm.

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.

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".

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.
