MRCNF1007Cylindrical Roller Bearing — 35 mm ID, 62 mm OD, 14 mm Width, Single Row, Separable, Machined Brass Cage, One-Direction Location

Product Description

What this part is:

MRC NF1007 single row cylindrical roller bearing. Bore Diameter: 35 mm (1.3780 in). Outside Diameter: 62 mm (2.4409 in). Overall Width: 14 mm (0.5512 in). Number Of Rows: 1. Rolling Elements: Cylindrical Roller. Cage Material: Machined brass. Bearing Material: Steel inner and outer rings, steel rollers. Ground raceways, separable rings. Federal cataloguing item name: BEARING, ROLLER, CYLINDRICAL, NSN 3110-00-801-9908.

Decoding the designation:

NF — single rib on the outer ring, two ribs on the inner ring. Carries axial load in one direction. The mirror of NJ, which puts two ribs on the outer ring and one on the inner.

10 — ISO dimension series 10, the extra-light section, giving a 62 mm outside diameter and a 14 mm width on a 35 mm bore.

07 — bore code, 07 x 5 = 35 mm.

M — machined brass cage.

What these specs mean in practice:

A cylindrical roller contacts the raceway along a line rather than at a point, so a cylindrical roller bearing carries substantially more radial load than a ball bearing on the same envelope. The ribs carry the axial component; the NF arrangement takes it in one direction.

Separable construction: the inner ring assembly and the outer ring mount independently, so both rings take an interference fit on their own seats.

A machined brass cage runs at higher temperature and tolerates marginal lubrication better than a polymer cage, which is why it is specified on aerospace and gas-turbine accessory drives.

Mounting data:

Bore Type: Straight. Ribs: one on the outer ring, two on the inner ring. Axial location: single direction. The rings are separable and seat independently.

Quantity and configuration:

Unit Quantity: 1 Pc. Single bearing, inner ring assembly and outer ring together.

The following are cross-referenced to National Stock Number 3110-00-801-9908 in the federal cataloguing record and interchange at stock-number level: SKF R107KD100 (SKF Aeroengine, CAGE 38443); SKF 468559 (SKF USA, CAGE 52676); Federal-Mogul KU1007DJA1093 (CAGE 01212), Federal-Mogul being MRC’s parent; General Electric 416B848P1, 705B441P1, 705B441P2 and 705B441P3 (CAGE 07482 / 24446), the numbers GE equipment drawings call this bearing out under.

Same 35 x 62 x 14 mm envelope, different rib arrangements and therefore different axial behaviour: N1007 and NU1007 are non-locating, NJ1007 locates in one direction with the ribs mirrored, NUP1007 locates in both. Common spellings: NF-1007, NF 1007, NF1007M, NF-1007-M.
