DIAMOND-GROOVE BUSHINGS

 


DG




 
FEATURES: This bushing is designed for cast-in-place or potted installation. Diamond-knurled OD provides excellent holding strength against both rotational and axial forces. Since the bushing's OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.

STANDARD SIZES: see Dimensions page for part numbers and standard ID drill sizes. The prices shown apply to standard bushings only, with any standard USA or metric ID size within the stated range.
 DG-26-16-.1875   Standard bushing, 3/16" ID
 DG-26-16-.1772   Standard bushing,
4.50mm ID (.1772")
 DG-26-16U-.1875   Add "U" for Unground OD

STANDARD ID TOLERANCE:
 From #55 to 1/4"   +.0001/+.0004
 Over 1/4 to 3/4"   +.0001/+.0005
 Over 3/4 to 1-1/2"   +.0002/+.0006

REAMER ID TOLERANCE: Reamer bushings have a different tolerance range than drill bushings:
 From #60 to 1/4"   +.0005/+.0008
 Over 1/4 to 3/4"   +.0006/+.0010
 Over 3/4 to 1-1/2"   +.0008/+.0012
To order bushings with a reamer tolerance, add "-REAMER" to the part number:
 DG-26-16-.1875-REAMER (Special)

NO-COUNTERBORE ON LONG BUSHINGS: Extremely long bushings with a small ID size (marked * ) are counterbored according to ANSI standards for proper drill-bearing length to eliminate binding and heat buildup. Add "-NCB" for applications that require these bushings without a counterbore:
 DG-26-16-.1875-NCB (Special)

MATERIAL: 1144 Stressproof steel, heat treated to achieve Rc 62-64 ID hardness. Other materials readily available by special order (see Specials). DFARS and RoHS compliant.
