{"product_id":"chiaravalli-chpc-63-chm-040-worm-gearbox-pre-stage","title":"Chiaravalli CHPC 63 + CHM 040 Worm Gearbox with Pre-Stage Module (ratios 90–300:1)","description":"\u003cp\u003eCHPC 63 pre-stage module (ratio 3:1, IEC 63 B5 motor flange) coupled to a CHM 040 worm gearbox — total ratios 90–300:1 in one compact unit, for the slow output speeds a single worm stage cannot reach. Aluminium CHM housing, hollow output shaft with 18 mm bore, keyed; optional output flanges as the CHM 040. The dimension sheet gives the combined unit (CHPC\/CHM 63+040); the gearbox connected to the pre-stage has the pre-stage's Z1 input dimension. Supplied in the universal position — it can be mounted in any orientation. 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 63 B5 motor (11 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":"90:1 \/ 0.18 kW","offer_id":46283693129813,"sku":"CHPC63-CHM040 R.90 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"120:1 \/ 0.18 kW","offer_id":46283693162581,"sku":"CHPC63-CHM040 R.120 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"150:1 \/ 0.18 kW","offer_id":46283693195349,"sku":"CHPC63-CHM040 R.150 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"180:1 \/ 0.18 kW","offer_id":46283693228117,"sku":"CHPC63-CHM040 R.180 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"240:1 \/ 0.18 kW","offer_id":46283693260885,"sku":"CHPC63-CHM040 R.240 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"300:1 \/ 0.18 kW","offer_id":46283693293653,"sku":"CHPC63-CHM040 R.300 0.18kW","price":0.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/1595\/4773\/files\/chpc-chm-photo.jpg?v=1791267106","url":"https:\/\/nusaf.co.za\/products\/chiaravalli-chpc-63-chm-040-worm-gearbox-pre-stage","provider":"Nusaf Dynamic Technologies","version":"1.0","type":"link"}
