The friction between the rolling element and the sleeve edge is small, suitable for high-speed rotation. According to the presence or absence of retaining edges in the ring, there are single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, as well as double row cylindrical roller bearings such as NNU and NN. This bearing is a separable structure with inner and outer rings.

High temperature bearings have the following characteristics compared to ordinary bearings: greater load-bearing capacity, able to withstand greater pressure; anti-oxidation and anti-corrosion, can be used normally in humid and rainy environments without rusting; High hardness and wear resistance, keeping it smooth and shiny on the surface all the time; It is particularly resistant to strong impact and biting, and can withstand high temperatures up to 500 ℃ or 800 ℃. It can also maintain its characteristics in high temperature environments and provide its original use effect; Moreover, high-temperature bearings have self-lubricating properties, and do not require lubricants at low speeds. The load is 1.4 times that of ordinary bearings, and the average lifespan is more than five times longer than that of ordinary bearings.

The service life of bearings has been extended, and there are fewer discarded bearings, reducing the emission of waste materials; Long lifespan! Saved you logistics costs, procurement expenses, and labor installation costs;

The raceway and rolling elements of cylindrical roller high-temperature bearings have geometric shapes. After improved design, the new structural design of the retaining edge and roller end face not only enhances the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the retaining edge, thereby improving the performance of the bearing.
