Hydraulic Nut HMVC ..E Series (Inch System)

Specifications

How to choose Hydraulic Tools

Points to check when selecting, with the values for this product (Hydraulic Nut HMVC ..E Series (Inch System)).

1. 1. Match the mating thread standard

   This product: Thread shape American National Standard threads Class 3 / ACME general-purpose threads Class 3G

   Hydraulic nuts are screwed onto the thread of a shaft or sleeve, so they cannot be fitted if the thread form does not match. Confirm whether the thread is metric or inch, and select a product whose specification, including pitch, matches the mating thread standard.

2. 2. Select the size for the nominal thread diameter

   This product: Thread diameter range 1.967 - 37.410 in.

   Hydraulic nuts are sized by nominal thread diameter. Identify the corresponding nominal thread diameter from the bearing bore or the model number of the adapter sleeve or withdrawal sleeve, and select a product whose thread diameter range includes that diameter.

3. 3. Check the applicable shaft diameter

   The listed products have applicable shaft diameters of 50 to 1000 mm. Confirm that the shaft on which the bearing or sleeve will be mounted falls within the nut's applicable range. Larger-diameter types have larger and heavier bodies.

4. 4. Match pump pressure and maximum hydraulic pressure

   This product: Maximum Hydraulic Operating Pressure 80 MPa (HMVC 60E or less), 40 MPa (HMVC 62–100E), 25 MPa (HMVC 102E or more)

   The listed products have a maximum hydraulic pressure of 60 to 80 MPa. Confirm that the rated pressure of the hydraulic pump, hose and coupler used in combination matches the nut's maximum hydraulic pressure. Pressing force is determined by the product of piston area and hydraulic pressure.

5. 5. Required press-in amount and stroke

   With tapered fits, the bearing must be pushed in a set distance. Confirm that the required press-in amount falls within the piston travel, and allow for the work of retracting the nut and re-threading it if the travel is insufficient.

6. 6. Prepare handling means for the mass

   The listed products have a mass of 19 to 136 kg. Large sizes are difficult to hold by hand, so confirm whether eyebolts are provided and prepare slings or a crane. The presence of accessories such as tommy bars and thread lubricant also affects workability.
