Product Description

What this part is

NTN 7004T1GGMP5 is a single-row precision angular contact ball bearing, flush-ground for universal matching with a medium preload. Bore Diameter: 20 mm. Outside Diameter: 42 mm. Width: 12 mm. Contact Angle: 30°. Cage Material: Phenolic. Preload: Medium. Precision Class: ABEC 5 / P5. Closure Type: Open.

Decoding the designation

7004 — ISO 70 series (extra-light section), bore code 04, 20 x 42 x 12 mm. No angle letter: 30° contact angle.

T1 — phenolic resin cage.

G — single bearing with flush-ground faces, universally matchable in back-to-back, face-to-face or tandem sets.

GM — Medium preload when paired.

P5 — ISO class 5 tolerances, equivalent to ABEC 5.

What these specs mean in practice

The 30° angle carries a higher axial share than a 15° spindle bearing. Flush-ground universal faces let any two or more of these bearings be combined into a matched set, and the medium preload raises stiffness for machining spindles. The phenolic cage is light and runs well at speed with oil or grease.

Mounting data

Fillet Radius r: 0.6 mm. Fillet Radius r1: 0.3 mm. Shaft Abutment da min: 24.5 mm. Housing Abutment Da max: 37.5 mm.
