SKF BTW 80 CTN9 SP Bearing

SKF BTW 80 CTN9/SP is a super‑precision double‑direction angular contact thrust ball bearing engineered for high‑accuracy axial loading in both directions. It accepts a bore of 80 mm, an outer diameter of 125 mm, and a width of 54 mm, with a 60° contact angle that supports tight runout and stiff axial guidance at high speeds. As part of SKF’s BTW family, the CTN9/SP designation identifies the high‑precision SP variant, designed for demanding machine‑tool and metrology applications where axial thrust must be transmitted cleanly without compromising precision. The 80×125×54 mm footprint fits standard mounting geometries, making it suitable for precision spindles and other rotary assemblies that require reliable, bidirectional axial support in a compact package.
