Rolling Elements: Cylindrical Roller. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel.

Decoding the designation

N1016 — ISO N-type single-row cylindrical roller bearing, 80 x 125 x 22 mm. The N type carries two guide ribs on the inner ring and a plain outer ring, so the outer ring separates and the bearing floats axially.

P4Y — special dimensional accuracy with ISO class 4 running accuracy.

What these specs mean in practice

A cylindrical roller bearing carries radial load through line contact rather than point contact, so radial capacity and stiffness are high for the envelope. Cylindrical roller bearings have no contact angle.

The separable plain outer ring lets the bearing take thermal shaft growth without transmitting axial load, which is the reason N-type bearings sit at the non-locating end of a machine tool spindle.

Precision Class: ISO class 4 / P4Y covers both dimensional and running accuracy. Lubricant: grease or oil.

Quantity and configuration

Unit Quantity: 1 Pc.

Interchange guidance

Standard-class N1016 bearings from other makers: SKF N 1016, FAG N1016, NTN N1016 and Koyo N1016. These are not the P4Y precision execution.
