FAGNU2034EXLM1C3Cylindrical Roller Bearing – Straight Bore, 170 mm ID, 260 mm OD, 54 mm Width, 1 Row, C3 Internal clearance

Product Description

What this part is

FAG NU2034-E-XL-M1-C3 single-row cylindrical roller bearing. Bore 170 mm, outside diameter 260 mm, width 54 mm. Series: NU 22 (NU2000 heavy section). Straight bore, machined brass cage, open on both faces. Country of origin: Germany.

Decoding the designation

NU: one row of cylindrical rollers with two integral ribs on the outer ring and a ribless inner ring, so the bearing is non-locating and the shaft is free to move axially inside it. E-XL: reinforced, high-capacity Schaeffler design. M1: machined brass cage. C3: radial internal clearance greater than normal.

Published ratings

Dynamic load rating: 610 kN. Static load rating: 830 kN. Limiting speed: 2,600 rpm. Operating range: −30 °C to 150 °C. Mass: 23.5 lb. Lubrication: oil.

What these specs mean in practice

The E-XL reinforced design fits a longer, fuller roller set inside the same envelope, which is where the 610 kN dynamic rating comes from — several times what a ball bearing of the same size carries. As a non-locating bearing it absorbs shaft thermal growth in a two-bearing arrangement while the second position handles axial location. C3 clearance suits a tight shaft fit and a hot inner ring, and the machined brass cage tolerates high acceleration and marginal lubrication better than a pressed cage.

Quantity and configuration

One bearing. Unit quantity: 1 Pc.

Fitting notes

Straight 170 mm bore on a cylindrical shaft seat. Radial load only; axial location comes from the locating bearing in the arrangement.
