די NJ 305 E איז א סילינדריקאַל וואַל שייַכעס from the NJ 305 E series, designed to handle high radial loads and moderate axial loads in one direction. דאָ ס אַ דיטיילד ברייקדאַון פון זייַן ספּעסאַפאַקיישאַנז:
NJ 305 E Bearing Specifications:
טיפּ: Single-row cylindrical roller bearing with NJ design (one integral flanged outer ring and one flangeless inner ring).
יסאָ סטאַנדאַרד: Complies with יסאָ 15:2017 (metric rolling bearings).
נודנע דיאַמעטער (ד): 25 mm (305 series = 25 מם נודניק).
ויסווייניקסט דיאַמעטער (ד): 62 mm.
ברייט (ב): 17 mm.
דינאַמיש לאָוד שאַץ (ג): ~30.5 kN (וועריז דורך פאַבריקאַנט).
סטאַטיק לאָוד שאַץ (C₀): ~22.0 kN.
ספּיד רייטינג (שמירן / אָיל): ~10,000 / 13,000 רפּם (אַפּפּראָקס., depends on lubrication).
Cage Material: טיפּיקאַללי stamped steel or machined brass (וועריז דורך פאַבריקאַנט).
Suffix “E”: Indicates reinforced (high-capacity) roller design with optimized internal geometry for higher load capacity compared to standard NJ 305.
שליסל פֿעיִקייטן:
Axial Displacement: די NJ design allows axial displacement of the shaft relative to the housing, making it suitable for locating/non-locating bearing arrangements.
High Radial Load Capacity: Handles heavy radial loads efficiently.
Moderate Thrust Load Capacity: Can support axial loads in one direction (due to one-sided flange).
Precision & Durability: די “E” suffix indicates improved internal geometry for better performance.
