Product Description

What this part is

An SNR 7013 C DU J74 angular contact ball bearing set, two rings supplied as a duplex-matched pair. Steel rings, steel balls, open on both faces.

Decoding the designation

70 — ISO 70 dimension series; bore code 13 gives a 65 mm bore.
C — 15° contact angle.
DU — duplex, supplied as a matched pair.
J74 — light preload. J84 is the medium grade.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity, which is the usual choice for a spindle front position. Light preload keeps the running temperature and frictional torque low against some loss of axial stiffness. Being ground as a duplex pair, the two rings seat together and reach the marked preload with no shim stack. SNR’s J74 and J84 are preload codes and sit in a different register from the J20, J30, J40 and J50 radial clearance codes.

Published specifications

Bore: 65 mm (2.5591 in)

Total width of the pair: 36 mm (1.4173 in)
Contact angle: 15°
Preload: light (J74)
Rolling elements: steel balls, single row per ring
Closure: open both faces

Quantity and configuration

2 Pcs, supplied as one duplex-matched pair.

Interchange guidance

ISO base number 7013, angle-designated 7013C. Searchable forms are 7013CDUJ74, 7013 C DU J74, 7013-C-DU-J74 and 7013CDU. A 7013AC or 7013B ring carries a 25° or 40° contact angle on the same envelope, so both are related sizes rather than interchanges. A 7013 C DU J84 is the medium preload grade and is likewise a related size.
