MRDE500498336 Radial Motor","description":"\u003cdiv\u003e\u003cp\u003eThe Riva Calzoni MRDE500\/498-336 Radial Piston Motor (part number 5247788) is a radial hydraulic motor in the MRD\/MRDE family from Riva Calzoni Oleodinamica SpA, engineered to convert pressurized fluid into rotational motion at low speed and high torque. MRDE denotes the expanded, dual-displacement version, where the drive shaft’s eccentric cam can move radially to vary displacement as the motor operates. Its mechanism uses a telescoping cylinder and piston arrangement that transmits force through a fluid column, enabling self-aligning seals, reduced wear, and high starting torque with smooth, pulsation-minimized performance. This model is specified for demanding hydraulic drive applications and is cataloged as MRDE500\/498-336 with the associated part number 5247788. \u003c\/p\u003e\u003c\/div\u003e","brand":"RIVA","offers":[{"title":"New","offer_id":46284588122346,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-023.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/riva-calzoni-s-p-a-mrde500498336-radial-motor","provider":"GTG Hardware","version":"1.0","type":"link"}
