A single-row ball screw support bearing from NSK’s TAC series. Bore Diameter: 40 mm. Outside Diameter: 72 mm. Overall Width: 15 mm. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel.
TAC — NSK’s ball screw support bearing series. These are angular contact ball bearings built with a high contact angle and thick rings, so the assembly is stiff in the axial direction and holds a ball screw’s axial position under thrust.
40 — Bore Diameter: 40 mm.
72 — Outside Diameter: 72 mm.
A 15 mm width on a 40 mm bore and a 72 mm outside diameter gives a thick radial section for the width. The extra ring material is what makes the bearing axially stiff, which is the property a ball screw end support is selected for.
Axial stiffness at the screw end determines how closely a machine can hold position under cutting load, so ball screw support bearings are rated on stiffness and running accuracy rather than on radial capacity.
Bore Diameter: 1.5748 in. Outside Diameter: 2.8346 in. Overall Width: 0.5906 in. Bore Type: Straight, so the inner ring mounts directly on the screw journal and is clamped by a locknut against a shoulder.
Unit Quantity: 1 Pc.
