NU2308 Cylindrical Roller Bearing.jpg

China NU2308 Cylindrical Roller Bearing Suppliers - 40*90*33 Split Bearing for High Load Capacity & Speed Factory

Structural Design of High-Performance Bearings

,

This advanced bearing features a split structure, designed without flanges on the outer ring and equipped with flanges on both sides of the inner ring. This unique design enables the shaft to move freely in both axial directions relative to the bearing seat. Ideal for use as a floating end bearing, it boasts a significant radial load capacity, a low friction coefficient, and is optimized for high-speed rotation. As a leading China supplier and manufacturer, our factory ensures the highest quality standards to meet your industrial needs.

    Key Features of NU2308 Cylindrical Roller Bearing

    Large Load Capacity

    The roller and raceway feature line contact design, providing high radial load capacity to withstand heavy and impact loads. Ideal for heavy-duty machinery such as rock drills, crushers, and rolling mills.

    High-Speed Rotation

    Featuring a low friction coefficient with limiting speeds comparable to deep groove ball bearings. Reduced friction between rolling elements and ribs maintains exceptional performance in high-speed equipment like printing machinery.

    Axial Displacement Adaptability

    NU and N types accommodate axial movement to adjust for thermal expansion or housing mounting discrepancies, performing reliably as free-end supports in fluctuating shaft systems.

    Easy Installation & Disassembly

    Separable ring design allows inner or outer rings to be detached effortlessly. This simplifies assembly, disassembly, routine maintenance, and inspection while reducing downtime and operational costs.

    Wide Industrial Applicability

    Engineered for versatile operations across mining, metallurgy, construction, chemical, and woodworking sectors, including tunneling machines, forklifts, and vibrating screens.

    Industrial Applications

    Industrial Machinery

    Supports precision machine tool spindles to maintain rotational accuracy and stability under heavy radial loads. In concrete mixing machinery, it reliably sustains continuous radial forces on the main mixing shaft.

    Agricultural Machinery

    Applied within tractor gearboxes to support gear shafts against transmission forces, ensuring smooth power delivery. In harvesters, it supports conveyor rollers for consistent, jam-free material transport.

    Automotive Industry

    Utilized in vehicle transmissions to support input, output, and intermediate shafts under gear meshing forces. Also suitable for specialized or modified wheel hub assemblies handling combined loads.

    Other Specialized Fields

    Supports rotating crankshafts in HVAC air-conditioning compressors to guarantee stable compression cycles, as well as industrial ventilation drive shafts to sustain air movement efficiency.

    Frequently Asked Questions (FAQ)

    What are the key dimensions and load ratings of the NU2308 bearing?
    The NU2308 cylindrical roller bearing has an inner diameter of 40 mm, an outer diameter of 90 mm, and a width of 33 mm. It provides a dynamic load rating (Cr) of 82.5 kN, a static load rating (Cor) of 88 kN, and weighs approximately 0.951 kg.
    How does the NU design accommodate axial displacement?
    In the NU-type design, the outer ring features double integral flanges while the inner ring has no flanges. This allows the inner ring and rollers to move axially relative to each other, accommodating shaft thermal expansion and installation adjustments as a free-end bearing.
    What are the limiting operating speeds for NU2308 bearings?
    The NU2308 bearing operates up to a limiting speed of 7,000 r/min when lubricated with grease, and up to 8,200 r/min with oil lubrication under recommended operating temperatures (-40℃ to +120℃).
    What steel grade and precision standards are used?
    The bearings are precision-manufactured from high-grade GCr15 Chrome Steel and are available across multiple precision classes, including P0 (standard), P6, P5, P4, and P2, with radial clearances ranging from C0 to C5.
    Can custom branding, packaging, or OEM specifications be supplied?
    Yes. We provide complete OEM services, including custom laser marking, tailored internal clearances, custom packaging boxes, specific labeling, barcodes, and export-standard wooden cases or pallets.
    What is covered under the 12-month bearing warranty?
    Our 12-month warranty from the date of shipment covers all defects in raw materials and manufacturing workmanship. The warranty does not cover issues resulting from improper installation, non-recommended usage, or physical damage.
