All worms and worm gears stocked right hand only.
Worm made of case hardened and ground steel (HV 620 – 700).
Worm gear made of CuZn37Mn3Al2PbSi-S40 or CuZn37Mn3Al2Si┬░. On request made of plastic or HGW 2083.

┬░Note:
Since July 21, 2021, the exceptions of the EU Directive 2011/65/EU (RoHS II) regarding the use of lead as an alloying element in steel (Exception 6a in Annex III) and in copper alloys (Exception 6c in Annex III) expire. In order to give our customers legal certainty with regard to the requirements of the RoHS directive, we have decided to gradually convert our standard worm gear sets to alloys with a lead content of ÔëĄ 0.1% by weight (worm: 11SMn30 / worm wheel: CuZn37Mn3Al2Si).

You can find an up-to-date overview of the materials that have already been converted on the product pages in our online shop. You can recognize these by the ┬░ marking and by the new item numbers without spaces (e.g. new: R17U80B┬░ / e.g. old: R 17U 80B).

The output torque rating (T2) applies to the initial speed of 2800 rpm at the worm (shaft).
The efficiency values (see table in worm gear set catalog) are guidelines. The bearing, lubrication, speed, and installation, in addition to the lead angle, can influence efficiency.

Gears may be combined only with worms of the same axial distance and with the same transmission ratio.
Worms or worm gears from other manufacturers may not be paired with the counterpiece from Framo Morat. It is almost always necessary to adjust the toothing specifications.
All dimensions can be adapted upon request.
