Design Specs - English
How To Create A Part Number:
Model – Bar Style – Bar Width – Height – Separators – Length – Bracket (fixed) – Bracket (moving)
Example: NSB-PR-4.50-55-1-72.89-#1IN-#1IN
⇒ Length is specified in inches, to two decimals. It is the distance between flanges
⇒ (see formula on carrier side view diagram)
⇒ Specify bracket type and arrangement # for each end
Cross Bar Styles:
– PR = Poly Roller (over bolted aluminum round bar)
– RB = Aluminum Round Bar
– AF = Aluminum Flat Bar

Carrier Side View

Travel/2 + CL (+ Offset Distance From Center*) = Length
Dynatect recommends mounting the stationary end of the carrier at the center of travel, minimizing the required length.
In cases where center mounting is not possible, add the distance offset from center to the carrier length calculation.

Mounting Brackets
Specify bracket arrangement and direction of flange. Mounting holes can be inward facing or outward facing.
Example: #1 arrangement and inward facing holes = #1-IN
Example: #4 arrangement and outward facing holes = #4-OUT
