OIL-GROOVE BUSHINGS

Press-Fit Bushings (P, PM) Head Press-Fit Bushings (H, HM) Renewable Bushings (SF, SFM, FM)		Type 1 With Oil Hole 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 1 (WITH OIL HOLE): This type of oil groove has a single radial hole in the bushing wall to allow coolant to flow from a manifold passage to the bushing's internal oil grooves. Bushing must be correctly oriented during installation so that the radial hole lines up with the manifold passage. OIL GROOVE STYLES: Type 1 Oil-Groove Bushings (with Oil Hole) are available in eight styles, to suit different operating conditions, lubrication requirements, and individual preferences:   AC     Helix   AA     Helix, Open Bottom   AB     Helix, Open Both Ends   AL     Straight   AR     Loop   AU     Double Loop   AN     Figure 8   AX     Double Figure 8 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 x 1/32" deep. Oil holes are 1/4" diameter. ORDERING EXAMPLES:   P-48-16-.5000-AC   P bushing with AC-style oil groove, 1/2" ID   H-48-16-.5000-AC   H bushing with AC-style oil groove, 1/2" ID   SF-48-16-.5000-AC   SF bushing with AC-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).   P-48-16-.5000-AC-AAA MATERIAL: 1144 Stressproof steel, heat treated to achieve Rc 62-64 ID hardness. Other materials readily available by special order (see Specials).
