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.

Deep groove ball bearings are widely used in many industries for decades. A deep groove is formed on each inner and outer ring of the bearings enabling them to sustain radial and axial loads or even combinations of both. As the leading deep groove ball bearing factory, TPI Bearings owns abundant experience in designing and producing this type of bearing.

The Deep Groove Ball Bearing, known as 6202-C3 Generic, has an inner diameter of 15 mm, an outer diameter of 35 mm and a thickness of 11 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".

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.

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 6202-C3 Generic, has an inner diameter of 15 mm, an outer diameter of 35 mm and a thickness of 11 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 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".

TPI deep groove ball bearing factory cooperates with the best grease manufacturers in the world which allows us to suggest and apply the best lubricating selection for our customers.

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 6202-C3 Generic, has an inner diameter of 15 mm, an outer diameter of 35 mm and a thickness of 11 mm.

Bearing life is usually expressed as the number of hours an individual bearing will operate before material fatigue develops on either the raceways or the rolling element. The usual life rating for industrial applications is called “L10” life. The L10 life is the number of hours which that 90% of bearings will survive； or, conversely, 10% of bearings will have failed in the L10 number of service hours.

Two types of seals, contact and non-contact, were well designed by TPI precision roller bearings to effectively reduce the external dust entering the bearing while rotating.
