Solid Disk Handwheels EN 521.8

Product description

Information

These solid disk handwheels EN 521.8 have a recess in the hub to accept EN 000.8 or EN 000.3 position indicators.

If application requires occasional removal of position indicator, handwheel may be ordered upon request with an EN 576 cover disk to shroud the empty recess.

For heavier torque adjustments, the hub bore can be provided with a keyway.

The shape of these handwheels does not only meet all demands for modern design but also functions ergonomically.

Resistant to solvents, oils, grease and other chemical agents.

Installation Instructions

Install the handwheel to the spindle, create cross hole if it's required and fasten it with the set screw.
Turn the spindle to the starting point (0 position).
Move the position indicator to the 0 position by turning the outer gear wheel.
Install the position indicator into the recess of the hub and fasten it with a set screw. To avoid deformation of the housing, do not apply unnecessary excessive torque!
Check by turning the handwheel to ensure that the starting position of the spindle coincides with the 0 position of the two pointers (Position Indicators EN 000.8) or respectively pointer and counter (Position Indicators EN 000.3). If necessary, take out and readjust the position indicator.
