Cast iron CHM housing, hollow output shaft with 45 mm bore, keyed; optional output flanges as the CHM 130. The dimension sheet gives the combined unit (CHPC\/CHM 80(90)+130); 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). Lubricated with mineral oil; the oil quantity is set for the mounting position, so the orientation matters when ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSupplied without motor.\u003c\/strong\u003e Fits an IEC 90 B5 motor (24 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":"98:1 \/ 1.5 kW","offer_id":46283742740565,"sku":"CHPC90-CHM130 R.98 1.5kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"122.5:1 \/ 1.5 kW","offer_id":46283742773333,"sku":"CHPC90-CHM130 R.122.5 1.5kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"147:1 \/ 1.5 kW","offer_id":46283742806101,"sku":"CHPC90-CHM130 R.147 1.5kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"196:1 \/ 1.5 kW","offer_id":46283742838869,"sku":"CHPC90-CHM130 R.196 1.5kW","price":0.0,"currency_code":"ZAR","in_stock":true},{"title":"245:1 \/ 1.1 kW","offer_id":46283742871637,"sku":"CHPC90-CHM130 R.245 1.1kW","price":0.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/1595\/4773\/files\/chpc-chm-photo_7a2f1742-d6b4-460c-9439-ace4050fa2fe.jpg?v=1791267295","url":"https:\/\/nusaf.co.za\/products\/chiaravalli-chpc-90-chm-130-worm-gearbox-pre-stage","provider":"Nusaf Dynamic Technologies","version":"1.0","type":"link"}
