DRILL-JIG BUSHINGS, OIL-GROOVE BUSHINGS, Oil-Groove Bushings Without Oil Feed

OIL-GROOVE BUSHINGS

Press-Fit Bushings (P, PM)

Head Press-Fit Bushings (H, HM)

Renewable Bushings (SF, SFM, FM)

Type 3
Without Oil Feed

FEATURES: Oil grooves are specially designed coolant passageways in a bushing's ID wall. Oil grooves are available on almost any bushing type, including press fit, head press fit, and renewable. Use when you need complete drill lubrication and cooling, such as when drilling hardened steel, or when bushings are used as bearings.

TYPE 3 (WITHOUT OIL FEED): This type of oil groove has no external feed from a manifold passage to the bushing's internal oil grooves, so all coolant must enter at the ID entrance end. This type is also commonly used as a bearing bushing, packed with oil or grease.

OIL GROOVE STYLES: Type 3 Oil-Groove Bushings (without Oil Feed) are available in nine styles, to suit different operating conditions, lubrication requirements, and individual preferences:

	AF				Helix
	AD				Helix, Open Bottom
	AE				Helix, Open Both Ends
	AK				Straight
	AT				Loop
	AW				Double Loop
	AQ				Figure 8
	AZ				Double Figure 8
	AM				Helix with ID Groove

SIZES & TECHNICAL DATA: Oil grooves are available for bushings with ID sizes from 3/8" to 8", and lengths from 1/2" to 8" (oil grooves stop 1/8" short of each end). Oil grooves are 1/16" wide and 1/32" deep.

ORDERING EXAMPLES:

	P-48-16-.5000-AF		P bushing with AF-style oil groove, 1/2" ID
	H-48-16-.5000-AF		H bushing with AF-style oil groove, 1/2" ID
	SF-48-16-.5000-AF		SF bushing with AF-style oil groove, 1/2" ID

OPTIONAL WIPER: To guard against dirt and chips entering the bushing ID (usually from the drill-entrance end), order oil-groove bushings with a wiper end. Order style AAA for headless bushings, style AAB or AAC for head-type bushings (see Technical Information).
