Installation
Drill and ream holes to the proper length and the nominal diameter plus .001” maximum, minus .000” of the
heater diameter 3/16”, 3/8”, 1/2”, 5/8”, etc. The heaters are sized so that they never exceed .005 less than the
nominal diameter and always at least .001 under the nominal diameter for a slide fit. These close fits insure
rapid heat transfer from the heater and also help keep the unit as cool as possible, which contributes to long
life. Always finish-ream drilled or cast holes to insure a smooth, uniform metal to metal contact. A knockout
hole should be provided if possible to aid removal. The receptacle hole should be free from oil before heater
installation to avoid contamination and short life. Do not use set screws to hold heaters in place. Lead wires,
especially when the heater is in a moving die or platen, should be supported to prevent excessive stress on the
lead wires. | | |
On many applications, plastic material, machine oil, and/or moisture may be present. Cycling of a cartridge
heater causes these materials to be absorbed. Heaters, therefore, should be carefully selected for these applica-
tions utilizing sealed terminations.
When installing high watt density cartridge heaters (CSH Series), see the graph below for allowable watt
densities at different fit tolerances and operating temperatures.

The watt densities are based on a unit installed in mild steel. Different materials affect the above values, 1.e.
the lower the thermal conductivity of the material, the lower the maximum allowable watts per square inch.
