        NSK 7005CTYNSUHP4 Super Precision Angular Contact Ball Bearing Overview

        • H heavy preload at the highest listed preload level
        • 67 N/µm axial rigidity for the 7005C P4 configuration
        • TYN cage with SU universal arrangement

        7005CTYNSUHP4 uses a 292 N catalog preload and -24 µm measured axial clearance.


        The H suffix gives this version the highest preload and axial-rigidity values among the listed EL, L, M, and H variants.


        Speed, heat, fit, and lubrication decisions therefore have to be evaluated against the complete heavy-preload spindle arrangement.

        Apter Power provides 7005CTYNSUHP4 configuration review, quotation support, and sourcing coordination.

        Important Notice: Confirm that the spindle design specifies the H preload before using this heavy-preload 7005C configuration.
        • Preload level: The H suffix specifies 292 N, the highest value in the listed preload set.
        • Axial rigidity: The catalog value is 67 N/µm for 7005CTYNSUHP4.
        • Internal condition: Measured axial clearance is -24 µm for the heavy-preload version.
        • Selection boundary: H must not be treated as the same internal condition as EL, L, or M.
        • Heavy-preload effect: The highest listed preload and rigidity require explicit heat-generation review.
        • Grease boundary: The catalog limiting speed with grease is 32,000 rpm.
        • Oil-air boundary: The catalog limiting speed with oil-air is 38,000 rpm.
        • Operating limit: Actual speed must account for cooling, lubricant delivery, fits, and the completed bearing set.
        • P4 requirement: Shaft and housing geometry must preserve the precision class through assembly.
        • Universal arrangement: The SU suffix supports arrangement selection only when orientation and mating bearings are controlled.
        • Seat dimensions: The 25 × 47 × 12 mm envelope establishes the shaft, housing, and shoulder interfaces.
        • Contact angle: The 15-degree geometry fixes the angular-contact load path for the spindle design.
        • High-rigidity spindles: The H preload serves precision positions requiring the highest listed rigidity in this variant set.
        • Machine-tool heads: P4 accuracy supports spindle assemblies with tightly controlled running accuracy.
        • Grouped arrangements: SU coding supports engineered paired or multi-bearing layouts.
        • Heavy-preload replacements: Installed H-grade positions require the same complete suffix and arrangement review.
        Description
        The 7005CTYNSUHP4 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 H suffix identifies the heavy preload selection and must remain part of the ordered designation.

        The 7005CTYNSUHP4 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 292 N preload, 67 N/µm axial rigidity, and -24 µm measured axial clearance distinguish this variant from the EL, L, M, and H alternatives.
        Alternative Names
        NSK 7005C H preload P4 spindle bearing 7005CTYNSUHP4-APN
        Technical notes
        7005CTYNSUHP4 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 H suffix mean on 7005CTYNSUHP4?
        It identifies NSK’s heavy preload grade for this 7005C P4 bearing. Keep the complete suffix in the RFQ because another preload grade changes stiffness and internal condition.
        Can 7005CTYNSUHP4 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 7005CTYNSUHP4?
        The catalog value is 292 N preload with 67 N/µm axial rigidity and -24 µm measured axial clearance for the stated reference arrangement.
        What load ratings apply to 7005CTYNSUHP4?
        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 7005CTYNSUHP4?
        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 7005CTYNSUHP4?
        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 7005CTYNSUHP4 include?
        State the exact 7005CTYNSUHP4 designation, quantity, single or matched arrangement, spindle application, lubrication method, and any pairing or packaging requirement.
