Quick to mount on all<br />
spindle configurations:<br />
• ANSI American Standard<br />
<strong>Chucks</strong> for A1 and A2 spindles<br />
• Taper-Key Drive <strong>Chucks</strong> for<br />
#00, #0, #1, #2 spindles<br />
• Cam-Lock <strong>Chucks</strong> for D1-3",<br />
D1-4", D1-5", DI-6" and D1-8"<br />
spindles<br />
• Threaded-Nose <strong>Chucks</strong> for<br />
2 1 ⁄4" - 8 TPI spindles<br />
• Plain-Back <strong>Chucks</strong> for 5", 5 3 ⁄4",<br />
and 6 1 ⁄4" plain-back spindles<br />
Hardinge-Sjogren Speed <strong>Collet</strong> <strong>Chucks</strong> provide greater collet capacity, reduced<br />
machining time and increased accuracy as compared to using a 3-jaw chuck. The<br />
manual chuck easily mounts to your lathe’s spindle, enabling the use of precision<br />
hardened and ground collets.<br />
The 5C Hardinge threaded or taper spindle nose versions allow the use of step<br />
chucks with closers for larger diameter secondary operation work. The 5C and 3J<br />
spindles can accept Hardinge Sure-Grip ® Expanding collets which grip parts with<br />
1 ⁄ 2" (12.70mm) to 4" (101.60mm) bores.<br />
Increase Capacity: The Hardinge-Sjogren Speed <strong>Collet</strong> Chuck increases the lathe’s<br />
capacity 25% to 40% compared to a lathe with a standard collet closing attachment.<br />
The Hardinge-Sjogren Speed <strong>Collet</strong> Chuck takes advantage of the full spindle bore<br />
— there is no draw tube.<br />
Save Time: An almost effortless turn of the hand wheel automatically opens or<br />
closes the collet, releasing or gripping the workpiece as desired. The chuck is easily<br />
adjusted to grip a thin wall part which may be crushed with a standard collet closer.<br />
Use Precision-machined or Emergency <strong>Collet</strong>s: The Precision-machined collets<br />
provide an extremely long life and superior TIR as compared with a 3-jaw chuck.<br />
The emergency collet is for chucking diameters when a standard Precision-machined<br />
collet is not available.<br />
Sjogren Speed <strong>Collet</strong> <strong>Chucks</strong><br />
For Manual Machines<br />
Use standard 5C, 2J, 3J and 22J collets on toolroom<br />
lathes, engine lathes, and grinding machines to increase<br />
your machine capacity!<br />
CAUTION: Hardinge-Sjogren Speed <strong>Collet</strong> <strong>Chucks</strong> are designed to operate at speeds of 4,000 rpm<br />
or less. <strong>Chucks</strong> that feature a Hardinge threaded- or taper-nose spindle should not be operated in<br />
excess of 3,000 rpm when a step chuck with closer is used.<br />
