Aluminium housings, hollow output shaft with 25 mm bore, keyed; output flanges as the CH 05. Overall length R1 123 mm, pre-stage offset I2 50 mm; the gearbox connected to the pre-stage has the module's Z1 input dimension (14\/120); other dimensions as the CH 05. Filled for life with synthetic oil — no oil changes, no maintenance; aluminium housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSupplied without motor.\u003c\/strong\u003e Fits an IEC 71 B5 motor (14 mm shaft).

The catalogue notes the installed power is sometimes more than the gear needs — always check the output torque against your load, and ask us if in doubt.\u003c\/p\u003e","brand":"Chiaravalli","offers":[{"title":"84:1 \/ 0.25 kW","offer_id":46283915362389,"sku":"CHPC71-CH05 R.84 0.25kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"108:1 \/ 0.25 kW","offer_id":46283915395157,"sku":"CHPC71-CH05 R.108 0.25kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"135:1 \/ 0.25 kW","offer_id":46283915427925,"sku":"CHPC71-CH05 R.135 0.25kW","price":0.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/1595\/4773\/files\/chpc-ch-photo_fabdeb51-cc19-4112-a69c-57f69051fd15.jpg?v=1791268446","url":"https:\/\/nusaf.co.za\/products\/chiaravalli-chpc-71-ch-05-worm-gearbox-pre-stage","provider":"Nusaf Dynamic Technologies","version":"1.0","type":"link"}
