Mounting data which depend on the size of thread on the withdrawal sleeve. The hydraulic nut is mounted onto the thread of withdrawal sleeve.



Example 1:

Bearing: 23264K

Withdrawal sleeve: AOH 3264G (The thread size on the sleeve is Tr 340×5), so ADP hydraulic nut HMV68E is selected.

Then you can find the mounting data on Table 2:

Preload of the oil pump pressure, 10.8MPa(108 bar or 1566 psi), the piston area of ADP HMV68E is 28400mm2 ,which can generate a thrust force of 306720N (28400×7.7=306720)

The converted drive angle range is between 344° and 387°.

Example 2:

Alternatively the withdrawal sleeve: AOH 3264 (The thread size on the sleeve is Tr 350×5) is a lager thread on the sleeve and ADP hydraulic nut HMV70E is selected.

As HMV70 is lager than HMV68, the piston area is 29900mm2 , Preload of the oil pump pressure is 10.3MPa(103 bar or 1495 psi), which can generate a thrust fore of 307970N (29900×10.3=307970)

The converted drive angle range is between 344° and 387°.

Special case
Very often the hydraulic nut is to be mounted onto the thread of the shaft end. Depending on the thread size of shaft end, the preload pressure can be calculated by the following method.

Example 3:

Bearing :23264K

Withdrawal sleeve: AOH3264G

Thread of shaft end: Tr300×4

Then ADP hydraulic nut HMV60 is selected, the piston area is 23600mm2 , as the thrust foce of the preload is 306720N (Example 1, or 2), so the preload pressure of oil pump will be 13MPa.

(306720÷23600=12.99≈13)

(307970÷23600=13.04≈13)

The converted drive angle range is remained the same range which is between 344° and 387°.
