NAB model air shaft brake is a standard friction plate brake, it is driven by air pressure. It can replace HAC HDB model friction disc brake fully with same specification. 

Installation Instruction

1. Mounted onto shaft

NAB model brake installs conical shaft spanned tube onto shaft in following order:

1) Embed the key into shaft inside, and get brake body through shaft.

2) Find the key, and install conical shaft spanned tube into where the key is embedded.

3) Align the cut-out of conical shaft spanned tube to the bolt hole of shaft spanned disc and use three screws to fasten them. When fasten, pay attention to see the dial indicator, and the level deviation of fitting surface of pistol. Try to reduce the deviation to its minimum level and fasten interlaced.

2.Installation onto machine table

Supported by the brake torque, fix flange portion by 4 screw bolts, put torque bolt into cut-in of brake body to prevent turning.

The squareness between cover and shaft to install flange must be controlled under 0.05mm.

Note:In order not to produce load to brake axis, install the conical shaft spanned tube onto shaft before making sure that there is no clearance between machine table.
