I NJ 305 E yi cylindrical roller bearing from the NJ 305 E series, designed to handle high radial loads and moderate axial loads in one direction. Nantsi inkcazo eneenkcukacha zayo:
NJ 305 E Bearing Specifications:
Uhlobo: Single-row cylindrical roller bearing with NJ design (one integral flanged outer ring and one flangeless inner ring).
ISO Standard: Complies with ISO 15:2017 (metric rolling bearings).
Bore Diameter (d): 25 mm (305 series = 25 mm bore).
Ububanzi bangaphandle (D): 62 mm.
Ububanzi (B): 17 mm.
Ubungakanani bomthwalo oguqukayo (C): ~30.5 kN (iyahluka ngokomenzi).
Umlinganiselo womthwalo omileyo (C₀): ~22.0 kN.
Isantya sokukala (Igrisi/i-oyile): ~10,000 / 13,000 rpm (malunga., depends on lubrication).
Cage Material: Ngokuqhelekileyo stamped steel or machined brass (iyahluka ngokomenzi).
Suffix “E”: Indicates reinforced (high-capacity) roller design with optimized internal geometry for higher load capacity compared to standard NJ 305.
Ezona mpawu:
Axial Displacement: I 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).
Ukuchaneka & Durability: I “E” suffix indicates improved internal geometry for better performance.
Izicelo eziqhelekileyo:
Iinjini zombane & gearboxes
Oomatshini bemizi-mveliso (pumps, iicompressors)
Automotive transmissions
Conveyor systems
Iispindle zesixhobo somatshini (when paired with another bearing)
Iibheringi ezilinganayo:
NJ 305 EM (with machined brass cage)
NJ 305 ECP (with polymer cage)
NJ 305 ECM (optimized for high speeds)
NUP 305 E (if axial load support in both directions is needed)
Manufacturers & Availability:
SKF, I-FAG / APHO, NSK, NTN, TIMKEN produce this bearing.
Check interchangeability if replacing with non-“E” variants.
