Standard Airejet Spindles,
.296 to 4.000

Thru Hole Type

Blind Hole Type
Airejet Spindles with diametrically opposed, standard size jets
are used for inspecting bore diameters above .296 through 4.000.
Two types are offered: thru hole and blind or counterbored hole.
The blind hole type may also be used for checking thru holes.
Available standard material is long wear life steel, with optional
heavy chrome plating or titanium nitride (TiN) coating for
increased wear life. Spindles larger than a 4.000 diameter, spindles with three or more
jets for checking average diameter and "clover-leaf" or lobed
conditions, and spindles of special lengths, shapes, etc. are available
on special order. When ordering, designate desired spindle,
components, instrument type and amplification..

Standard Small Jet Spindles,
.296 to .859

These are the same as Standard Airejet Spindles in the range
.296 through .859 except that a smaller size jet is used. This permits
checking of narrow lands, thinner parts, and closer to the bottom of
blind holes. They are used with Precisionaire Instruments of 2,000 to 1
amplification or higher, and will achieve 3/4 of basic amplification.
Use with an Air to Electronic (A/E) Column to obtain full amplification.
Maximum part tolerance is .0025.

Standard Small Jet Spindles,
.1250 to .2960

Standard Small Jet Spindles in the range .1250 through .2960
are different in design than those of standard spindles above .2960.
Spindles for this size range are available as standard in long wear
life steel and can be TiN coated. These spindles are used with
Precisionaire Instruments having amplifications of 2,000 to 1 or
higher and achieve 3/4 of the basic amplification. For full amplification,
use with an A/E Column. Maximum part tolerance is .0025.

Standard Small Jet Spindles,
.093 to .1250

Small Jet Spindles in the .093 through .1250 range are made of
long wear life steel and can be TiN coated. These spindles are used
with Precisionaire Instruments having amplifications of 5,000 to 1
or higher and achieve 1/5 of the basic amplification. For full amplification,
use with an A/E Column. Maximum part tolerance is .0005.

Balljet Spindles

Balljet Spindles are recommended for gaging I.D.'s in soft or porous parts,
for narrow lands and for gaging bores to the hole edge. Standard Balljet
Spindles are stocked in semi-finished blanks ranging from .375 to 2.000
for thru and blind holes. Standard material is long wear steel. Engineered
Balljet Spindles are available. Maximum part tolerance is .0025.

Leafjet Spindles

Leafjet Spindles are semi-standard, contact-type spindles for checking
laminated bores, rough surfaces and for gaging thru or blind holes in
which oil grooves, keyways or cross-drilled holes prevent the use of
standard Airejet Spindles. Leafjet components are stocked and spindles
are made to size per order. Leafjet Spindles are for checking hole diameters
.4375 and larger and may be designed for checking tolerances in excess
of those possible with Airejet and Balljet Spindles. They can also be used
for checking to the extreme bottom of blind holes and to the extreme
edge of holes and grooves.
