    QHK0509

    Open End Needle Roller Bearing to DIN 618 Part 1. 5mm Bore.
    SKU: QHK0509
    RFQ Delivery: -
    Product specifications
    Bore Diameter [d]5
    Diameter [A]9
    Dimension [W] +0/-0.29
    Dynamic Load Rating [N]2450
    Static Load Rating [N]1990
    Limiting Speed - Grease [rpm]27000
    Limiting Speed - Oil [rpm]40000
    Mass (g)1.9

    Material

    Outer Ring: Carburised Chrome Molybdenum Steel.
    Rollers: Special carbonitriding heat treated Steel. Crowning reduces edge load stress concentration.
    Cage: Case hardened and tempered or soft-nitrided Steel.

    Performance

    Recommended Bearing Fit in Housing: Steel: N6 (N7). Light Alloy: R6 (R7) (<1.6 Ra Circularity / Cylindricity <IT4).
    Shaft Without Inner Ring: h5 (h6). Shaft With Inner Ring: k5 (j6) (58-64 Hrc <0.8 Ra).

    Other Info.

    Needle roller bearings are available in inch sizes and a variety of alternative bore dias., outside dias. and lengths. Also available with double rows and seals.
    Please contact Sales with your specific requirements for a quotation.
    3mm to 22mm dia bore needle roller bearings are ‘F Type’ drawn cup types which offer:

    • Three times longer service life
    • 1.5 x greater allowable static load
    • Reduction and stabilisation of initial mounting.

    Further technical information available on request.

    Available in inch sizes and a variety of alternative bore diameters, outside diameters and lengths.

    Please contact Sales for a quote.

    Notes:
    This part uses a patented “Pre-bent” production method where the rollers and cage are assembled into the outer ring first, and the bent edge rib is bent prior to heat treatment. This gives the rib (at the bent edge side) the same hardness as that of the other areas. At the same time, it eliminates the conventional limitation that the bearing must be press-fit with a jig placed on the marked side face. This allows the bearing to be press-fit in either direction. Optimal heat-treatment contributes to longer bearing life.
