Product Description

What this part is

NTN HSA918DTBTG08UP is a set of high-speed angular contact ball bearings from NTN’s HSA machine-tool spindle series. Bore Diameter: 90 mm. Width: 18 mm per bearing. Rolling Elements: Ball. Unit Quantity: 4 Pcs.

Decoding the designation

HSA — NTN high-speed angular contact ball bearing series, built for machine-tool spindles.

918 — bore code 18, a 90 mm bore.

UP — NTN ultra-high precision grade.

What these specs mean in practice

The HSA series is optimised for high spindle speeds, with internal geometry that limits heat generation at speed. The UP grade holds running accuracy tighter than standard precision classes, for spindles where runout drives surface finish.

Quantity and configuration

Unit Quantity: 4 Pcs. Four bearings in the DTBT execution, supplied as one set.
