Longer length and additional sliders |

A longer length passive slider in UniSlide base with
hard coat anodizing.

Longer
length sliders provide greater stability for large or
cantilevered loads. The amount of bearing surface area
remains the same as the standard sliders. Mounting holes
consist of two pairs of holes. One pair is identical
to the standard slider, referenced from the center of
the slider. The other pair is identical to standard
slider referenced from the slider end.
Additional passive or floating sliders
may also be added to the UniSlide Assembly to lend additional
support to long, bulky loads.

If a motorized
UniSlide Assembly will accumulate more than 200,000 cycles
of operation or will be used in a production capacity
8 hours per day, a hard coat anodized finish can be applied
to the dovetail ways to prolong life. This coat is 0.002"
thick, measures Rockwell C 70 and is dyed black. This
option is specified by prefacing the part number with
the letter "Z", i.e. ZMB4015BJ-S4.
The price formula for each Series is given in the price
list. Electroless nickel coating is also available.

Polyurethane way covers
with attaching plates are available for protection against
dust and grit. They extend over and above the UniSlide
Assembly as follows:

Since the collapsed or compressed bellows requires additional
base length, please add 1/3 of free travel length to the
nominal base length of the assembly. For example, the
free travel of the MB4021P10J-S4 with the standard slider
length of 4" and without way covers is 17". If way covers
are desired, the dovetail base must be increased by 17"/3,
which, to the nearest 3" length increment, is 6". Therefore,
Model MB4027P10J, having a 27" nominal length base will
accommodate the compressed bellows and is the correct
choice. This option is specified by appending the Part
Number with the letters "WC",
i.e., MB4021P10J-S4-WC.
The price for each unit with way covers is given in the
price list. |
| Outboard
limit switches |

See
also Limit Switches. When the standard internal adjustable
limit switches are not available or adequate for an application,
outboard limit switches may be useful. For example, when
it is necessary to over travel a stop point or to provide
more stops than the normal two, these switches may be
used. Adjacent photo shows a movable switch in a track
mounted lengthwise along the side of the UniSlide Assembly
base. A 1/4" plate with cam is mounted on the slider and
activates the switch when it passes over it. The maximum
number of limit switches is only limited by the nominal
base length. These switches can be wired to stop travel
until restarted, change speed or be active in only one
direction. |
