        NSK 7005CTYNSUELP4 Super Precision Angular Contact Ball Bearing Overview

        • EL extra-light preload at the lowest end of the listed preload set
        • P4 accuracy with a 15-degree angular-contact design
        • SU universal arrangement for precision spindle configuration

        7005CTYNSUELP4 applies 30 N preload and 24 N/µm axial rigidity to the 7005C bearing envelope.


        A measured axial clearance of -1 µm distinguishes the EL internal condition from the L, M, and H versions.


        The TYN cage and published grease and oil-air speed limits place the exact suffix within high-speed precision-bearing selection work.

        Apter Power supports 7005CTYNSUELP4 suffix review, quotation, and precision-bearing procurement coordination.

        Important Notice: Preserve the EL suffix and confirm the spindle arrangement before replacing another 7005C preload grade.
        • Preload level: The EL designation specifies 30 N, the lowest listed preload in the EL, L, M, and H set.
        • Axial rigidity: The catalog value is 24 N/µm for this extra-light variant.
        • Internal condition: Measured axial clearance is -1 µm for 7005CTYNSUELP4.
        • Suffix control: The complete EL code separates this bearing from the higher-preload L, M, and H versions.
        • Grease lubrication: The published limiting speed is 32,000 rpm.
        • Oil-air lubrication: The published limiting speed increases to 38,000 rpm.
        • Contact geometry: The 15-degree contact angle defines the angular-contact load path.
        • Speed interpretation: Actual spindle speed remains dependent on lubrication, fits, cooling, and the complete bearing arrangement.
        • Universal arrangement: The SU suffix identifies a bearing intended for universal arrangement planning.
        • Accuracy class: P4 running accuracy sets the precision requirement for mating seats and spindle runout.
        • Seat envelope: The 25 × 47 × 12 mm boundary dimensions control shaft, housing, and shoulder fit.
        • Cage identity: The TYN cage designation must remain part of the exact replacement configuration.
        • High-speed spindles: The EL preload variant serves precision spindle positions prioritizing the lightest listed preload.
        • Grinding equipment: P4 accuracy supports precision grinding-spindle arrangements.
        • Compact cartridges: The 7005C envelope fits compact machine-tool spindle layouts.
        • Matched arrangements: The SU designation supports selection within paired or grouped precision-bearing layouts.
        Description
        The 7005CTYNSUELP4 is an NSK 7005C-series super-precision angular-contact ball bearing with a 25 mm bore, 47 mm outside diameter, 12 mm width, 15-degree contact angle, and P4 accuracy. The EL suffix identifies the extra-light preload selection and must remain part of the ordered designation.

        The 7005CTYNSUELP4 carries basic dynamic and static load ratings of 14.7 kN and 7.40 kN, with limiting speeds of 32,000 min⁻¹ under grease lubrication and 38,000 min⁻¹ under oil-air lubrication. Its 30 N preload, 24 N/µm axial rigidity, and -1 µm measured axial clearance distinguish this variant from the EL, L, M, and H alternatives.
        Alternative Names
        NSK 7005C EL preload P4 spindle bearing 7005CTYNSUELP4-APN
        Technical notes
        7005CTYNSUELP4 is a preload-specific precision bearing, not a generic 7005 replacement. Preserve the complete designation, mounting arrangement, orientation, spacer set, lubricant, fits, and spindle runout records; stop assembly if the replacement preload or matched-set condition cannot be confirmed.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What does the EL suffix mean on 7005CTYNSUELP4?
        It identifies NSK’s extra-light preload grade for this 7005C P4 bearing. Keep the complete suffix in the RFQ because another preload grade changes stiffness and internal condition.
        Can 7005CTYNSUELP4 be replaced by another 7005C P4 bearing?
        Only after the spindle design, preload, arrangement, cage, lubrication, and matched-set requirements are reviewed. Matching the 25 × 47 × 12 mm envelope alone is not sufficient.
        What preload data applies to 7005CTYNSUELP4?
        The catalog value is 30 N preload with 24 N/µm axial rigidity and -1 µm measured axial clearance for the stated reference arrangement.
        What load ratings apply to 7005CTYNSUELP4?
        The basic dynamic load rating is 14.7 kN and the basic static load rating is 7.40 kN. Apply the machine designer’s life and duty calculations before selection.
        What speed limits apply to 7005CTYNSUELP4?
        Catalog limiting speeds are 32,000 min⁻¹ with grease and 38,000 min⁻¹ with oil-air lubrication. Actual allowable speed depends on fit, preload, lubrication, cooling, and spindle condition.
        What should be checked before installing 7005CTYNSUELP4?
        Confirm shaft and housing fits, shoulder geometry, orientation, cleanliness, lubricant quantity, spacer condition, preload grade, and runout. Do not transmit installation force through the rolling elements.
        What should an RFQ for 7005CTYNSUELP4 include?
        State the exact 7005CTYNSUELP4 designation, quantity, single or matched arrangement, spindle application, lubrication method, and any pairing or packaging requirement.
