Ball bearings are precision-engineered components specifically designed to enable rotational or linear motion by reducing friction between two moving parts. They consist of a set of small, spherical balls housed within a ring or raceway. These balls distribute the load evenly, allowing for efficient, low-friction movement. The primary purpose of ball bearings is to support radial and axial loads while minimizing friction and wear, thereby extending the lifespan, and enhancing the efficiency of mechanical systems.

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.

Thrust Ball Bearings are specifically designed to handle axial loads. They have two bearing discs with raceways for the balls and are designed to support axial loads in one direction only. Thrust ball bearings are often used in applications where high axial load capacity is required.

RS offer a comprehensive selection of high-quality ball bearings in a variety of sizes and ratings. Our bearings are available in standard open types or for more challenging applications where added protection is required our sealed or shieled bearings are a great choice.

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.

Ball bearings also known as bearings and journal bearings are important mechanical components used in a wide range of applications. They are an integral part of various machines and mechanisms, from small household appliances to large industrial equipment.

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.

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.

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.

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 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".

Angular Contact Ball Bearings have a contact angle that enables forces to be transferred from one raceway to another at a specific angle. Ideal for handling combined radial and axial loads, these bearings have an angled raceway that allows them to support thrust in addition to radial forces. Angular contact bearings are available in two variants, single row, or double row.

Self Aligning Ball Bearings work in a similar way to standard ball bearings but feature two rows of balls which help with alignment by rotating in parallel with the outer ring. The inner ring features two raceways and the outer ring has one raceway.

Deep Groove Ball Bearings are one of the most used ball bearing types. They have a simple design and are easy to maintain. Deep groove ball bearings can manage both radial and axial loads in both directions and are ideal for use when a higher load capacity is required. Deep groove ball bearings are available in two variants, single row, or double row.

The Deep Groove Ball Bearing, known as 6306-32-2RS-C4-KOYO JTEKT, has an inner diameter of 32 mm, an outer diameter of 72 mm and a thickness of 19 mm.
