Sentry Precision s Value-Priced Sentry Precision Belt-Driven s The Sentry line is our standard building block spindle and is offered as a low-cost solution for many applications that call for a precision, high performance, standard design. Sentry spindles are built tough to deliver years of trouble-free performance. They feature a 1% inch design permanent grease lubrication, class 7 extra precision steel ball bearings, and can be applied at any attitude: horizontal, vertical, angular, ceiling, and side-mounted attitudes and rotational need. The Sentry line includes 6 models 1 cartridge and 5 block configurations: C17 Cartridge B35 Block B4 Block B5 Block Block B9 Block Sentry C17 Cartridge The C17 and B35 are the smallest Sentry spindles. These spindles are equipped with labyrinth seals. The Sentry C17 is our newest cartridge spindle, a drop-in replacement for the Gilman 1875. The C17 is available in two basic configurations and offered with three spindle nose options and two spindle mounting brackets. Built to stock, these configurations are offered with 1-2 week shipment and a standard one year warranty. The Sentry B35 is our smallest block spindle. Its compact size makes it ideal for small work that may require precision boring, drilling, and milling. The B35 is offered with a variety of motor drive packages up to 3 hp and 9, and features 4-6 week shipment. The B35 is a drop-in replacement for the Gilman 275. Models B4, B5,, and B9 represent the high end of the Sentry precision spindle line. These spindles are equipped with the patented SETCO AirShield and feature a standard 2-year warranty and 6-8 week shipment with standard options. All Sentry block-style spindles are equipped with a cross keyway and jackscrew holes, and can be configured with a variety of options such as triplex and quad front bearing arrangements, a wide assortment of motor drive packages, manual drawbar, and arrangement for through-spindle coolant. Like the B35, these spindles can be equipped with a variety of motor drive packages up to 1 hp and 13,5.

How to Size Your to the Application Selection Procedure 1. Determine the Power and requirements for the application. Refer to the cutting data found in tool catalogs. For assistance, consult the SETCO Application Group. 2. Locate the () on the chart and follow the line up until it intersects with the required Power (hp). 3. Continue up until it crosses the Size (model) line. This line is the minimum spindle size. 4. Verify that the Tool Overhang, measured from the spindle nose, falls within the maximum for the spindle. 5. For finish bore applications, verify the front spindle bearing is as large as the bore to be machined.
