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.

The Deep Groove Ball Bearing, known as 6010-2RS-NR-NSK NSK, has an inner diameter of 50 mm, an outer diameter of 80 mm and a thickness of 16 mm.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

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.

Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.

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".

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.

The Deep Groove Ball Bearing, known as 6010-2RS-NR-NSK NSK, has an inner diameter of 50 mm, an outer diameter of 80 mm and a thickness of 16 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.

Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes.

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.

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".

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.
