Dovetail Cavity Slide Accessories

Mounting Holes: Two types of mounting holes are offered on DC model slides; Style 1 or Style 2, as shown. Both hole styles have the advantage of not interfering with the mating way surfaces. Please specify longitudinal location when ordering.
Accordion Way Covers: Covers are recommended in applications (when way wipers are not adequate) where there are fine chips, dust or other foreign materials. These covers are not available on models DC2, DC3, two position models or on the cylinder end of stop rod models.
Low Friction Way Bearing Material: Bearing material is bonded to the mating surfaces of the saddle and gib. This material reduces the friction by approximately two-thirds (with lubrication) and provides smooth way motion with reduced stick-slip due to similar values for static and dynamic friction. It is recommended for high cycle applications, where the fit between the saddle and base require little or no clearance, where reduced friction is required for accuracy or where lubrication is prohibitive. Not available on DC2 and DC3 slides.
Way Wipers: The wipers on both ends of the saddle provide protection to way surfaces from chips, dirt and other contaminants. Way wipers should remain engaged with the slide base. To insure this engagement, the base length should be increased as follows:
DC2 thru DC8 models add 1 inch to the base length.
DC10 thru DC20 models add 2 inches to the base length.
Limit Switch Stop Rod: A heavy duty oil tight plug-in neutral position switch is available on all stop rod and CP model slides. This switch will give a signal at each end of the travel and does not require resetting when the travel limits are adjusted.
Limit Switch Side Mount: The heavy duty oil tight plug-in limit switches are available on all DC6 thru DC20 models that do not require way covers. Four types of switch arrangements are most commonly used: SA1 - neutral position switch for signal at each end of travel; SA2 - two switches for signal at each end of travel; SA3 - switch arrangement SA1 with feed switch; SA4 - switch arrangement SA2 with feed switch. Please specify switch arrangement number and length of feed stroke when ordering.
Acme Screw Take-Up Nut: By means of a simple adjustment, the backlash in the Acme screw nut assembly can be appreciably reduced. This adjustment can also be used to compensate for eventual wear in the lead screw nut. This accessory is available on all acme lead screw models except DC4. When ordering this accessory, 1" should be added to the base length.
Lubrication System - Manual or Automatic: Either system provides a convenient method of supplying a metered quantity of oil to the slide assembly with the inherent advantages of safety, cleanliness and savings both in time and lubricant. The manual system uses a pull handle pump lubricator, while the automatic system uses an electric gear motor pump lubricator with a built in time control that can be set to provide lubrication at proper time intervals. Either lubrication system can be supplied with nylon tubing, steel tubing, or an internal manifold in the saddle. Please specify nylon tubing, steel tubing or internal manifold when ordering. The lubricator will be supplied unmounted with six feet of nylon tubing.
