Product Description

What this part is

MPB HADR-105-P7-B-DUL is a precision single-row angular contact ball bearing made by MPB, the Keene, New Hampshire super-precision bearing operation of The Timken Company. Bore Diameter: 25 mm. Outside Diameter: 47 mm. Overall Width: 12 mm. The envelope matches the ISO 7005 boundary size.

Decoding the designation

HADR-105 — MPB’s number for the 25 x 47 x 12 mm angular contact size, the ISO 7005 envelope.

DU — universal duplex grinding. Each bearing is face-ground so two can be mounted back-to-back, face-to-face or in tandem.

What these specs mean in practice

Rolling Elements: Ball. Number Of Rows: 1. An angular contact bearing carries combined radial load and axial load in one direction; a universally ground pair carries axial load in both directions when mounted back-to-back or face-to-face. The 25 x 47 x 12 mm envelope suits machine-tool spindles, precision gearboxes and instrument drives.

Interchange guidance

MPN Variants: HADR105P7BDUL, HADR 105 P7 B DUL. The part shares boundary dimensions with ISO 7005 bearings; interchange depends on matching contact angle, precision class and preload.
