S4/S5 SFT series tubing by Bondioli & Pavesi (BY-PY)
Four-Tooth profile tubes are designed to provide maximum resistance and optimal telescoping within the space available between the yoke ears.
Free Rotation tubes allow the ends of the driveline to rotate with respect to each other up to 60°, thereby facilitating the alignment of the splined yokes to the PTO. Splined telescoping members can satisfy the requirements of applications with high torques, frequent sliding under load and extensions longer than those permitted by telescoping tubes.
SFT drivelines are designed to simplify maintenance work with less time required. Increasing the lubrication frequency to 50 hours was a positive improvement.
