Image 1 shows the power and torque values transmitted by single precision universal joints during permanent operation with a deflection angle of α = 10°.

Image 2 shows the adjustment value to be taken into consideration for greater deflection angles. For deflection angles less than 10°, e.g. between 0° to 5° you may increase the standard power value shown in image 1 by 25%.

Image 3 shows the service life of BÜCO’s maintenance-free precision universal joints with needle bearings depending on the impact factor (e.g. standard value 1.5 for an electromotor drive without flexible coupling), the adjustment value for the deflection angle and the torque value to be transmitted.

Image 4 shows the adjustment value for calculating the service life of BÜCO’s maintenance-free precision universal joints with needle bearings.

Image 5 shows the power and torque values transmitted by single precision universal joints (bracket version) during permanent operation and with a deflection angle of α = 10°.

Image 6 shows the adjustment value to be taken into consideration for greater deflection angles. For deflection angles between 0° to 5° you may increase the standard power value by 25%.
