What is the Reinforced Single Row Cylindrical Roller Bearing with Cage?

In the single row cylindrical roller bearing with cage suffix code for "E" bearing is to strengthen the cylindrical roller bearing, the structure of this bearing after optimization design, roller diameter increased, roller length lengthened, sometimes the number of rollers also increased, so greatly improve the bearing load capacity. In the design application, should be preferred.

Same as the world, our national standards in the diameter series for 2 series (size series 02.22).3 series (size series 03, 23) cylindrical roller bearings, into a series of increased reinforced cylindrical roller bearings.

Reinforced cylindrical roller bearings should be developed as a priority because of high load carrying capacity. In the market, it should be recommended to users first.

As the strengthened single row cylindrical roller bearing with cage is distributed in diameter 2 series, 3 series, and these two series of non-strengthened cylindrical roller bearings still exist, and can not be used interchangeably with the strengthened cylindrical roller bearings, so it is required from the order to production management should be clearly distinguished, must not be confused. In particular, the dimensions of RN type and RNU type reinforced and non-reinforced bearings are not the same, so if you are not careful, it will bring unnecessary trouble to production, sales and use.
