Product and series description
NSK BSN3062 is a BSBD / BSN double-row thrust bearing with single outer ring (bsn type). Customers search this exact designation for dimensions, load ratings, replacement and supplier quotation intent.
Integrated double-row DB layout; pre-greased with triple-lip DDU seals
Application role
Ball screw support bearings at the fixed or floating end of a precision screw drive carry axial loads, define system stiffness and accommodate thermal elongation. This designation must be evaluated with screw diameter, speed, nut preload and lubrication at both screw ends.

Ordering and identification
NSK ordering codes combine bore, TAC series, seal, arrangement, preload and accuracy suffixes. Example: 30 TAC 62 C DDG SU H PN7C. Do not assume a complete ordering designation from the base model code alone.
Send existing part marking, required seal type, arrangement (fixed/floating), preload class and accuracy requirement for engineering identification.
Selection and quotation guidance
For quotation, provide NSK designation, screw diameter, lead, speed, axial load, duty cycle, arrangement and environment. Golden Bearing Company supports engineering-led identification and quotation without publishing price, stock or availability claims on this page.
Evidence and commercial boundary
Published dimensions and load ratings for NSK BSN3062 follow the NSK Super Precision Bearings Catalogue. Preload, axial rigidity and starting torque for this size are not tabulated in the catalogue tables used here and require manufacturer verification.
Reference to NSK BSN3062 does not imply Golden Bearing Company distributes, stocks, authorises or represents NSK unless separately confirmed. No price, stock, availability or lead-time claims are made.
Product questions
NSK BSN3062 is a BSBD / BSN ball screw support bearing used in double-row thrust bearing with single outer ring (bsn type). Exact suffix configurations such as seal, arrangement and accuracy class must be confirmed against NSK manufacturer ordering data.
Catalogue extract dimensions: bore 30 mm, OD 62 mm, width 28 mm. See the specification table on this page for the full parameter list.
60° contact angle per NSK Super Precision Bearings Catalogue for this series.
Catalogue grease lubrication limiting speed: 4500 min-1. Oil-air limits require manufacturer verification where not tabulated in the extract.
Catalogue factory preload: 2625 N with axial rigidity 850 N/um and starting torque 0.19 Nm. Duplex DB/DF preload is not tabulated separately for this BSBD cartridge designation in the NSK catalogue tables used here.
Base family designation: BSN3062. Complete ordering codes add seal, arrangement, preload and accuracy suffixes (for example SU H PN7C on TAC C sizes). Send existing marking or application duty for identification support.
NSK application contexts include CNC machine tool feed drives, precision positioning axes, and heavy-load servo drives depending on series (TAC C rigidity vs TAC 03 load vs BSBD cartridge mounting).
