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.

TBBS only sells the highest quality radial ball bearings produced by high standard factories. Ideal for replacement and OEM applications.

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.

The Deep Groove Ball Bearing, known as 6001-Z-C3 Generic, has an inner diameter of 12 mm, an outer diameter of 28 mm and a thickness of 8 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.

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 6310-2RS and 6310-ZZ is a 50mm ball bearing that is found in many applications. The 6310-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The 6310-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing. If your application requires a 6310 ball bearing with only one seal or shield you can get this ball bearing and take one of the shields or seals off. This 50mm ball bearing is high quality and can take electric motor demands if needed.

This bearing can be found with the following part numbers on it: 6310-2RS, 6310 2RS, 6310 RS, 6310RS, 6310-ZZ, 6310 ZZ, 6310ZZ, 6310 Z

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 bearing coms in both a sealed and a shielded version. Please select between the two below. Select 2RS for a sealed bearing or ZZ for a shielded bearing.

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.

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.
