Ball Bearing 6209 2Rs C4 THE EXPERT ADVICE WHAT DO THE SUFFIXES MEAN RS 2RS 2RSH 2RS1 RSR 2RSR E EE LLU LLB DU DDU These suffixes mean with 1 or 2 rubber gaskets At 123Bearing we specify with the number 2 when the bearing is sealed on both sides C3 C4 Means increased internal game Often referred to as high speed this means that the bearing is designed for high rotational speeds and moderately high temperatures WARNING an increased internal clearance bearing will not operate optimally at low speeds We invite you to refer to the technical data sheet of the desired bearing to know its speed limit ZZ 2Z ZR Z These suffixes mean with 1 or 2 sheet metal baffles for dustproofing At 123Bearing we specify if the bearing is waterproof on both sides with ZZ TN9 TVH TVP G15 These suffixes indicate that the cage part of the bearing that keeps the balls at a distance from each other is made of polymer material In general made of fiberglassreinforced polyamide ABEC The ABEC standard is used to classify bearings by their machining tolerance This standard is regularly called into question because it does not include certain important technologies to guarantee a good functioning as well for the efficiency as for the lifetime of a bearing This standard is thus little used by123Bearing BHT VT This suffix indicates that the bearing is designed for very high operating temperatures In general it is indicated the temperature following this suffix Attention these bearings are not adapted to all the uses and will require a high temperature for an optimal lifetime HOW DO I KNOW IF MY BEARING IS STAINLESS STEEL A stainless steel bearing is usually magnetisable because it is a stainless steel AISI 420 harder and more shock resistant than the current stainless steel AISI 304 To check if your bearing is stainless steel just read the reference engraved on the side of the bearing This reference must begin with the prefix S meaning Stainless Steel WHAT IS THE DIFFERENCE BETWEEN ALL THE CHOICES I HAVE FOR MY REFERENCE EXAMPLE 62052RS Some bearings exist with more or less important variants large or small internal clearance special grease very high temperature etc These variants are always indicated by prefixes and suffixes in the reference For example the suffix 2RS means that the bearing is watertight thanks to a sealing flange on both sides of the bearing The suffix C3 will mean that the bearing has an increased internal clearance and that it will require a higher operating temperature or a higher rotational speed
