6306-ZZ-SKF - Deep groove ball bearing - 6306 zz
The Deep Groove Ball Bearing, known as 6207-2RS-NR-C3-SKF SKF, has an inner diameter of 35 mm, an outer diameter of 72 mm and a thickness of 17 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.
SKF shielded deep groove ball bearings are versatile ball bearings that suit high and very high speeds, they will accommodate both radial load and axial load in both directions. The ball bearings need very little maintenance. SKF deep groove ball bearings come in a range of different sizes. This range is single row ball bearings.Shielded (2Z) bearings are fitted with two metal dust shields to prevent the ingress of dirt and foreign matter. 2RZ bearings are 2Z bearings fitted with two low friction seals.
- Primarily intended for applications where the bearing inner ring rotates- Fitted in the outer ring and form a narrow gap with the inner ring- Both standard and C3 clearance available - Protect from dirt and debris without friction lossesApplication Information-Food and Beverage Industry-Pharmaceutica-Medical industry-Engines and Pumps-Medical Industry-PrintingMore InformationWhat are deep groove ball bearings?These are the most popular type of bearings and consists of an inner ring, outer ring, cage and the ball bearings. The bearings have deep raceway grooves. These type of bearings deliver high performance and high load capacity.Why used shielded ball bearings?Shielded ball bearings have a metal or plastic shield that is secured to the outer race of the bearing on each side of the bearing. Ball bearings that spin at high speeds require lubrication and a clean environment By having the ball bearings shielded this offers better protection against dirt and grease therefore the ball bearings have a longer lifespan.
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.

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".
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.
