The new type of the series DST-JGRM

Robust and with conventional connection sizes

The new type of the DST-JGRM series with optimised injection-moulded design is the robust alternative to a lead screw nut with flange. It is characterised by connection sizes and pitches that are identical to those of standard ball screw nuts. The special design enables easy installation and is especially suitable for radial loads. For high axial loads, the JGRM lead screw nut is also available with a stainless steel plate.

Connection sizes and pitches identical to those of standard ball screw nuts
Lubrication-free and maintenance-free due to iglidur® J high-performance polymer
Cost-effective through plastic injection moulding
Robust and strong design
Available in 2 installation sizes for threads in ø 14/16 and 18/20

Also available as "heavy duty" version with stainless steel plate!

More reliability
high axial load

This is why we have developed the "heavy duty" version

For higher axial loads, a heavy-duty version of the JGRM type is also available. The flange size of the heavy-duty JGRM lead screw nuts remains identical. The plate is fitted before the JGRM lead screw nut. Due to the stainless steel plate, the contact surface for force dissipation is enlarged as the screw heads no longer come into contact with the plastic. This version withstands axial loads up to 6MPa.

The heavy-duty version is perfect for applications with very high static loads that are not very dynamic, e.g. format adjustment. It is also available in two different sizes for threads in ø 14/16 and 18/20.
