PartNumber : CL-22032-TIPB ProductDescription : Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15? taper on the plunger tip with a mating taper on the bushing. The taper makes alignment easier and also eliminates any binding during retraction (also available with a straight plunger, for slightly greater positional accuracy). The version shown here has a blank machinable end for easy adaptation to various actuating devices, including automated setups. Precision ground body (also available with a slightly oversize unground body to allow custom grinding to size). Order plunger and bushing separately. Made in USA.
