NTN7816T1GGMP4Angular Contact Ball Bearing – 80 mm ID, 100 mm OD, 10 mm Width, 30° Contact Angle, Medium Preload, ABEC 7 / P4

Product Description

What this part is

NTN 7816T1G/GMP4 super-precision angular contact ball bearing, ISO 18 (thin) section. Bore Diameter: 80 mm. Outside Diameter: 100 mm. Width: 10 mm. Contact Angle: 30°. Preload: Medium. Precision Class: ABEC 7 / P4.

Decoding the designation

7816 — NTN 78 series (ISO 18 dimension series, very thin section), 80 mm bore. No angle letter: 30° contact angle.

G — universal flush-ground single bearing, matchable in DB, DF or DT with another G bearing.

GM — medium preload when paired.

P4 — ISO Class 4 precision, equivalent to ABEC 7.

What these specs mean in practice

The 30° contact angle gives more axial capacity and axial stiffness than the 15° 7816C execution in the same envelope. Medium preload raises system rigidity for spindles and rotary tables running at moderate speed. The very thin section saves radial space and mass.
