Tips of vacuum capacitors:

Torque/Direct Pull 
In variable capacitors, the linear sliding motion of the moving electrode assembly is converted to rotary tuning via a threaded shaft. The torque values given in the tables are the maximum torque needed to reach minimum capacitance when rotated with a standard lead screw; the torque required to tune away from minimum may be less than half this value.

For most variable capacitors, direct pulltuning is a possible alternative to rotary tuning. Maximum required pull forcevalues are also given in the tables.

Capacitance range end-stops are built intoevery variable capacitor. It is recommended that the user install his own stops to prevent damage from gear-reduction drives.

In addition, also offers several"Adjustable" capacitors which are designed to be operated as a fixed capacitor, but can be hand adjusted to any value within their range and  then locked in position with a locking nut.
