High quality cylindrical roller bearing nj 211

                                                                                        Product Description 

                            Our Cylindrical Roller Bearings are made from quality wear-resistant chrome steel, showcasing superior fatigue and wear resistance characteristics. To extend service life, the cage is crafted from specially engineered plastics, providing effective shock absorption and friction benefits. The precision of the bearing meets ABEC-5 standards, ensuring smooth operation of machinery. The clearance is meticulously processed to adapt to dynamic balance needs across various working conditions.

                                                                                                Features

 

                            The bearing design takes into account thermal deformation resistance, making it suitable for high-temperature operations.

The self-aligning structure reduces precision requirements for installation.

Stringent adherence to international quality standards, equipped with multiple testing devices to guarantee product consistency.

                                                                                        Application Range

                              Cylindrical roller bearings see extensive application in wind power generation, heavy machinery, and aerospace industries, particularly thriving under high loads and challenging operational environments. They provide superior reliability and stability to meet the demanding requirements of these industries.

                               The cylindrical rollers and raceways are linear contact bearings. The load capacity is large, and it mainly bears radial loads. The friction between the rolling element and the ring flange is small, and it is suitable for high-speed rotation. According to whether the ring has a flange or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, etc., and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure with an inner ring and an outer ring.

                               Cylindrical roller bearings with no flanges in the inner or outer rings can be moved axially and can be used as free-end bearings. Cylindrical roller bearings with double flanges on one side of the inner and outer rings and a single flange on the other side of the ferrule can withstand a certain degree of axial load in one direction. Generally, steel plate stamping cages are used, or copper alloy turned solid cages
