They provide a reasonably priced alternative to the GN 607 / GN 607.1 indexing plungers of the appropriate sizes. Plungers are inserted into position by holding them by the knurled knob. The wrench flats on the lock nut are exposed when the pin is retracted, so that the plunger can be easily tightened by means of an open-end wrench. Type C / CN offers a lock-out position for applications that require the plunger pin to be retracted for an extended period of time. After retracting the plunger pin, turn the knob 30 degrees, release the knob and it will stay in the retracted position via the indexing lock. In the rest position, the lock-out mechanism is completely concealed by the knob. GN 909.5 thin hexagon nuts are to be ordered separately. see also... • List of Indexing Plunger Types • Spacer Bushings GN 609.5 (to Limit the Thread Length) • Locating Bushings GN 412.2 / GN 412.4 • RoHS compliant Accessory • Thin hexagon nuts GN 909.5 On request • With red knob How to order (Inch) 1 2 3 GN 822.7-0.249-1/2X20-B How to order (Metric) 1 2 3 GN 822.7-6-M12x1.5-CN 2 | 3.1 Indexing, Locking, Blocking with Pins and Ball-Shaped Elements 1 Pin diameter d1 2 Thread d 2 3 Type 1 Pin diameter d1 2 Thread d 2 3 Type www.jwwinco.com | phone: 1-800-877-8351 GN 822.7 Mini Indexing Plungers continued Inch table 1 2 d1 d2 Pin −0.002 Bore +0.001 +0.003 Thread Dimensions in: inches - millimeters d3 d4 l1 l2 l3 min. k A/F Spring load ≈ Initial End .155 3.9 5/16 x 24 .83 21.1 .59 15.0 1.08 27.4 .20 5.1 .24 6.1 .65 16.5 .39 9.9 .90 lbf 4N 2.70 lbf 12 N .186 4.7 3/8 x 24 .98 24.9 .71 18.0 1.34 34.0 .24 6.1 .31 7.9 .79 20.1 .47 11.9 1.35 lbf 6N 3.60 lbf 16 N .249 6.3 1/2 x 20 1.10 27.9 .79 20.1 1.59 40.4 .28 7.1 .39 9.9 .93 23.6 .55 14.0 2.25 lbf 10 N 5.17 lbf 23 N .311 7.9 5/8 x 18 1.30 33.0 .91 23.1 1.87 47.5 .39 9.9 .47 11.9 1.00 25.4 .67 17.0 2.47 lbf 11 N 7.87 lbf 35 N Metric table 1 2 d1 d2 Pin h9 Bore +0.03 +0.08 4 5 6 6 7 8 10 .16 .20 .24 .24 .28 .31 .39 Dimensions in: millimeters - inches Thread d3 d4 l1 15 .59 27.5 1.08 5 .71 34 1.34 6 .71 34 1.34 6 .79 40.5 1.59 7 .79 40.5 1.59 7 .91 47.5 1.87 10 .91 47.5 1.87 10 M 8 M 8x1 21 M 10 M 10 x 1 25 M 10 M 10 x 1 25 M 12 M 12 x 1.5 28 1.10 20 M 12 M 12 x 1.5 28 1.10 20 M 16 M 16 x 1.5 33 1.30 23 M 16 M 16 x 1.5 33 1.30 23 .83 .98 .98 www.jwwinco.com | phone: 1-800-877-8351 18 18 l2 min. .20 .24 .24 .28 .28 .39 .39 l3 k A/F 16.5 .65 10 20 12 Spring load ≈ Initial 6 8 8 10 10 12 12 .24 .31 .31 20 .79 .79 12 .39 23.5 .93 14 .39 23.5 .93 14 .47 25.5 1.00 17 .47 25.5 1.00 17 End .39 4N .90 lbf 12 N 2.70 lbf .47 6N 1.35 lbf 16 N 3.60 lbf .47 6N 1.35 lbf 16 N 3.60 lbf .55 10 N 2.25 lbf 23 N 5.17 lbf .55 10 N 2.25 lbf 23 N 5.17 lbf .67 11 N 2.47 lbf 35 N 7.87 lbf .67 11 N 2.47 lbf 35 N 7.87 lbf 3.1 Indexing, Locking, Blocking with Pins and Ball-Shaped Elements | 3
