Aluminium CHM housing, hollow output shaft with 35 mm bore, keyed; optional output flanges as the CHM 090. The dimension sheet gives the combined unit (CHPC\/CHM 71+090); the gearbox connected to the pre-stage has the pre-stage's Z1 input dimension. Supplied for the B3 mounting position — tell us if you need a different orientation (see the mounting-position drawing). Filled for life with synthetic oil — no oil changes, no maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSupplied without motor.\u003c\/strong\u003e Fits an IEC 71 B5 motor (14 mm shaft).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow to pick from the table:\u003c\/strong\u003e with a standard 4-pole motor (1400 r\/min) the total ratio sets the output speed; P1 is the motor power the catalogue pairs with the row and the output torque is at that power. 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":"180:1 \/ 0.37 kW","offer_id":46283726389333,"sku":"CHPC71-CHM090 R.180 0.37kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"240:1 \/ 0.37 kW","offer_id":46283726422101,"sku":"CHPC71-CHM090 R.240 0.37kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"300:1 \/ 0.37 kW","offer_id":46283726454869,"sku":"CHPC71-CHM090 R.300 0.37kW","price":0.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/1595\/4773\/files\/chpc-chm-photo_bbed86b5-251b-4c71-b39b-b482d0bb0f42.jpg?v=1791267229","url":"https:\/\/nusaf.co.za\/products\/chiaravalli-chpc-71-chm-090-worm-gearbox-pre-stage","provider":"Nusaf Dynamic Technologies","version":"1.0","type":"link"}
