Overview

Made of a High Strength Bronze

AMDISK® CLAMP DISKS (ACD) and CLAMP RINGS (ACR) have been developed to lock connecting machine components to each other by hydraulic pressure. The simple and compact design allows these components to be used in a variety of applications.

 

 

AMDISK® CLAMP DISKS and RINGS are made of a high strength Bronze piston disk on which a Viton seal is vulcanized, allowing them to be used with any high pressure hydraulic fluid. The AMDISK® components are connected to a pressure port to allow hydraulic pressure up to 4000 psi. The holding force of these units depends on the amount of hydraulic pressure applied. 

 

Details

Mating Conditions for Clamp Disks:

The AMDISK® CLAMP DISKS require only a simple bore with a tolerance of I.S.O. H8, and a surface finish of 32 micro-inches. The hole for the AMDISK® CLAMP DISK is usually bored and hand polished with emery cloth to eliminate tool marks on the sealing surface. The port holes must be deburred and cleaned. The hole depth must be a minimum of 0.400".

Calculations for Clamp Disks:

 

The clamping force (Fc) on the slide must be sufficient to lock the sliding components to the machine ways by means of friction at surface (S) only. The force (Fc), on the Clamping Disks must act in an axial direction only. There should not be any side load on the seal lips and bronze disk.

Calculating The Holding Force:

H = ( A ) x ( p ) x ( µs ) x ( n ) x .95
= ( Fc ) x ( µs ) x ( n ) x .95
H = Total holding force [lbs]
Fc = Clamping force for a single disk [lbs]
n = Number of clamp disks
A = Area of one clamp disk in [in 2]
p = Hydraulic pressure [psi]
µs = Static coefficient of friction between
lubricated surfaces at S
= (.12) - steel on steel
= (.10) - steel on cast iron
= (.08) - steel on plastic material
.95 = Efficiency of hydraulic piston

Example:

To find number of clamp disks required:
Required holding force: 2,000 lbs.
Available pressure: 1,000 psi.
Max. disk size: 52 mm (A = 3.29 in2)
Surfaces: steel on steel (µs = 0.12)

Assembly Instructions (for ACD Clamp Disks):

1. Grease tapered bore of tapered sleeve and insert Amlok® Clamp Disk into tapered sleeve with seal
lip downward.
2. Center tapered sleeve on centering disk and push plunger downward to partially insert the seal lip of the Amlok® Clamp Disk into the centering disk. Fig. 4
3. Remove tapered sleeve with protruding seal
lip and insert into the greased housing bore. Fig. 5
4. Press plunger downward to insert Amlok® Clamp Disk into the housing bore.

Note: Assembly Tools consists of a plunger, tapered sleeve, and centering disk.
