Cylindrical Roller Bearing N/NU/NJ210-219EM Brass Cage/Steel Cage Electric Motor. Product Name: Cylindrical Roller Bearing. Product description Product Name: Cylindrical Roller Bearing Product size: full range of countries Product material: bearing steel Product use: general Number of rolling body columns: single column. Cylindrical roller bearings, the rolling elements are radial rolling bearings of cylindrical rollers. Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row bearings such as NU, NJ, NUP, N, NF and double row bearings such as NU and NN. The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, which is suitable for bearing heavy loads and impact loads. Small friction coefficient is suitable for high speed, and the limit speed is close to deep groove ball bearings. The N-type and U-type can move axially, can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, and can be used as free end support. Note: N type bearings are bearings without ribs on the outer ring (that is, the outer ring has no axial restriction on the rollers), while type NU bearings are bearings without ribs on the inner ring (that is, the inner ring has no axial restrictions on the rollers). Classification of bearings: Counting from left to right first or adding the first and second numbers together “6” means deep groove ball bearings (category 0) “4” means double row deep groove ball bearing (category 0) “2” or “1” means self-aligning ball bearing (basic model has four numbers) (category 1) “21”, “22”, “23” and “24” indicate spherical roller bearings. (3 categories) “N” denotes cylindrical roller bearings (including short cylindrical rollers and part of slender needle rollers) (category 2) “NU” Inner Ring No Rib Cylindrical Roller Bearings “NJ” inner ring single rib cylindrical roller bearing “NF” outer ring single rib. “NUP” inner ring single rib with flat retaining ring cylindrical roller bearings “N” Outer Ring No Rib Cylindrical Roller Bearings “NN” double row cylindrical rollers have no ribs on the outer ring. “NNU” double row cylindrical roller, inner ring without rib. The length of the roller is at least 5 times the diameter size, which is called needle roller bearing (category 4) “NA” Turned Cup Needle Roller Bearings “NK” stamped housing needle roller bearings “K” needle roller and cage assembly without inner and outer rings. “7” means angular contact ball bearing (category 6) “3” means tapered roller bearing (metric) (category 7) “51”, “52” and “53” indicate radial thrust ball bearings (a total of five numbers for the basic model) (8 categories) “81” means thrust short cylindrical roller bearing (category 9) “29” means thrust spherical roller bearing (category 9).
