What is 2RSH?
The 2RSH suffix indicates that the bearing has a rubber seal on both sides. If necessary the seals can easily removed if the application requires only 1 seal. The rubber seal protects the ingress of moisture, dust or other dirt. The bearings are filled with a high quality grease and are lubricated for life.
What do the letters on bearings mean?
The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D). The last two digits of the basic designation identify the size code of the bearing bore. The size code multiplied by 5 gives the bore diameter (d) in mm.
