Hydraulic Nut HMV ..E Series (Metric)

Specifications

How to choose Hydraulic Tools

Points to check when selecting, with the values for this product (Hydraulic Nut HMV ..E Series (Metric)).

1. 1. Match the mating thread standard

   This product: Thread shape ISO 965 / ISO 2901 metric threads

   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

   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

   This product: Applicable shaft diameter 50 - 1000 mm

   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 (HMV 60E or less), 40 MPa (HMV 62–100E), 25 MPa (HMV 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.

About Hydraulic Tools and all products

Description

Oil is fed into the nut to drive the piston, generating strong pushing force. Equipped with quick-connect couplings, available in sizes from HMV10E to 200E. Tommy bars and eyebolts are also supplied to aid handling of the nut.

FAQ

Q. What applications can the HMV E Series (Metric) hydraulic nut be used for?

A. It is used for mounting bearings on tapered fit surfaces and for removing adapter sleeves and withdrawal sleeves.

Q. What is the applicable shaft diameter range, thread form, and recommended hydraulic fluid for the HMV E Series?

A. The applicable shaft diameter is 50 - 1000 mm. The thread form is ISO 965 / ISO 2901 metric thread, and the recommended hydraulic fluid is LHMF 300.

Q. Does the maximum operating hydraulic pressure of the HMV E Series vary by size?

A. Yes, it does. HMV 60E and below is 80 MPa, HMV 62-100E is 40 MPa, and HMV 102E and above is 25 MPa.

Q. What accessories are included with the HMV E Series?

A. Spare piston seals and a maintenance kit are supplied as standard. HMV 54E and above also come standard with thread lubricant and a tommy bar, and HMV 94E and above are supplied with an eyebolt and a thread start position indicator.

Q. Where can the quick-connect coupling of the HMV E Series be mounted?

A. It can be mounted on either the front or the side of the nut.
