FAGNU1015Single Row Cylindrical Roller Bearing, Straight Bore, 75 x 115 x 20 mm, Non-Locating, Brass Cage

Product Description

What this part is

A FAG NU1015M1 single-row cylindrical roller bearing, 75 mm bore, 115 mm outside diameter, 20 mm width. Straight bore, open, machined brass cage, normal precision class, CN internal clearance.

Decoding the designation

NU is the non-locating cylindrical roller design, with guide ribs on the outer ring and a plain cylindrical inner ring. 10 is the dimension series, the light narrow section, and the bore code 15 gives 75 mm. M1 is a machined brass cage variant. No clearance suffix follows, so internal clearance is CN and the class is normal.

What these specs mean in practice

An NU bearing takes radial load only and lets the shaft move axially relative to the housing, which is what the floating position in a two-bearing arrangement needs. The light 10 series keeps the outside diameter and width small for the bore, which suits compact housings and higher speeds, at a lower radial rating than a 02 or 22 series bearing on the same shaft. The machined brass cage is roller-guided and tolerates higher temperature and heavier shock than pressed steel.

Quantity and configuration

1 Pc. Complete bearing: ribbed outer ring, roller and brass cage assembly, plain inner ring. Open both faces, without snap ring.

Fitting notes

The plain inner ring separates from the outer ring and can be heated and fitted to the shaft on its own. Axial location of the shaft comes from the second bearing in the arrangement.

Interchange guidance

SKF NU 1015 M and NSK NU1015M are same-spec equivalents at this envelope and clearance. FAG NU1015M1.C3 is a related size at greater than normal clearance; FAG NJ1015 is a related size with an inner-ring rib that locates the shaft in one direction.
