N series cylindrical roller bearings with catalogue dimensions, grease/oil speed values, load ratings and weights.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
The N design is commonly used as a non-locating cylindrical roller bearing arrangement that permits axial displacement of the shaft relative to the housing in both directions. This page groups every N-prefix model from the cylindrical roller bearing section into one series product and keeps the catalogue values searchable in HTML.
This page covers the N Series Cylindrical Roller Bearings as one catalogue series. Individual part numbers remain inside the technical table instead of being published as separate products. The supplied catalogue is the source of record for dimensions, ratings, speed data and weight shown below.
Cylindrical roller geometry is typically used where radial load capacity and a separable ring arrangement are important.
The supplied catalogue publishes grease and oil speed values alongside dimensions and load ratings for many models.
N, NF, NU, NJ and NUP are treated as separate design series here. Do not substitute one prefix only because dimensions look similar.
Every listed model is retained under its design prefix, with missing catalogue values left blank rather than guessed.

The table is transcribed from the supplied bearing catalogue. It is horizontally scrollable on phones and tablets so model numbers and technical values stay readable without forcing the page beyond the viewport.

Catalogue source pages: 26–34. Values and units are reproduced from the supplied catalogue. Missing fields remain blank/—; no missing value is estimated.
Use the complete design prefix and suffix because flange arrangement and construction can change the locating function.
Review both the load rating and the catalogue grease/oil speed lines against the real operating condition.
Confirm shaft/housing fits, axial displacement requirement, clearance and lubrication during RFQ.
These bearings are used in industrial shafts, gearboxes, machine tools, motors and other rotating equipment where radial load and axial-location strategy must be considered together. Confirm the bearing arrangement, not only the envelope dimensions.
Send the catalogue part number, required quantity, shaft/bore requirement, operating speed, radial/axial load information and any fit or sealing requirement. If the source table contains a blank field, our team can confirm it before quotation.
