OIL-GROOVE BUSHINGS

OPTIONAL WIPERS

45° TYP.
.020/.030 WIPER END
TYPICAL FLAT.
APPLICATIONS: SHARP
Oil grooves are available on most drill-bushing types, including P, H, BOTH ENDS
and SF. Use when you need complete drill lubrication and cooling,
such as when drilling hardened steel. Oil grooves are specially
designed coolant passageways in the bushing’s ID wall. Choose
from 25 different groove styles. End wipers are also available, to
keep out dirt and chips.

Coolant passage STYLE AAA
HEADLESS BUSHINGS
ORDERING EXAMPLES:
P-48-16-.5000-AJ P bushing with AJ oil groove, inch ID WIPER END
P-48-16-.4724-AJ P bushing with AJ oil groove, mm ID
(.4724 = 12.00mm)
P-48-16-.5000-AJ-AAA P bushing with AJ oil groove and AAA
wiper
SF-48-16-.5000-AJ SF bushing with AJ oil groove
THREE GENERAL TYPES:
1. With oil hole. A single radial hole in the bushing wall allows
coolant to flow from a manifold passage to the internal oil grooves.
Bushing must be installed to line up the radial hole with the
manifold passage.
2. With oil hole and external groove. OD groove allows coolant
to flow around the bushing, then through the radial hole in the
bushing’s wall to the internal oil grooves. Allows installing the
bushing at any orientation, and mounting bushings in series using STYLE ABB
a single manifold passage. This type is our most popular.
HEAD-TYPE BUSHINGS
3. Without oil feed. No external coolant feed through a manifold
passage, so all coolant enters through the top. This type is also
commonly used as a bearing bushing, packed with oil or grease.
OIL-GROOVE STYLES:
We offer a wide selection of oil-groove styles in each general type.
This allows choosing a style to suit various operating conditions,
lubrication requirements, and individual preferences.
OPTIONAL WIPERS:
To guard against dirt and chips entering the bushing ID, order
oil-groove bushings with a wiper end. Note: do not order an
oil-groove style that breaks out at the wiper end (AA, AB, AG, AH,
AD, or AE). Order style AAA for headless bushings (install wiper in
either direction). Order style ABB or ACC for head-type bushings.
