A press roll (10) for forming a controlled press nip (N) with an opposed roll (11), such as in a papermaking machine, including a rotatable roll shell (16) with a support shaft (14) extending axially through the roll shell and controllable hydrostatic support means (7) positioned between the roll shell and shaft for applying a controlled radial supporting force to the roll shell with the nip line of the roll shell forming a support plane (P) with the axis of the shaft and guide means (18, 18a) accommodating relative movement between the shaft and the roll shell in said support plane with the end guide means (18, 18a) including a V-shaped projection (19, 20) at each end of the shaft and on each side of the shaft, and adjustable blocks (25, 26; 27, 28; 42, 43) carried on the roll shell self-aligning bearings (35, 39) slidable against the end guide means on the shaft.
