Featuring a compact 40mm (1-9\/16 inch) diameter, this sheave is designed to handle maximum rope diameters of 3\/8 inch, making it ideal for various sailing and industrial applications. The sheave's construction includes a captive ball bearing system that combines a two-stage bearing setup: a set of ball bearings to minimize friction and a secondary full-contact bearing to ensure smooth operation under full load. This design allows for efficient load handling with minimal wear and tear, extending the longevity of your sheaves and maintaining optimal performance over time. The sheave's width measures 5\/8 inch (15.5mm), providing ample clearance for ropes and lines while maintaining a low profile suitable for tight spaces. With a maximum working load limit of 880 pounds (400kg), this component offers strength and durability for critical rigging needs. Weighing only 1.1 ounces (30 grams), the Ronstan Series 40 Orbit BB Sheave is lightweight and easy to install, reducing overall rig weight without sacrificing strength. Constructed with high-quality materials, this sheave ensures corrosion resistance and longevity in harsh environments. Whether used in sailboats, industrial lifting systems, or architectural applications, the RF48000 sheave provides a dependable solution for smooth rope guidance and load distribution. Its compact design and efficient bearing system make it a versatile choice for any demanding setup requiring reliable performance and ease of maintenance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBall bearing system: Two-stage bearing setup with ball bearings and full-contact bearing for low friction and smooth operation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompact size: 40mm (1-9\/16 inch) diameter with a width of 15.5mm (5\/8 inch), suitable for tight spaces.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty load capacity: Maximum working load limit of 880 pounds (400kg) for demanding applications.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLightweight construction: Weighs only 1.1 ounces (30 grams) for easy handling and installation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable materials: Corrosion-resistant construction ideal for marine and harsh environments.\u003c\/li\u003e\u003c\/ul\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":44572594044970,"sku":"97304","price":22.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/97304XL.jpg?v=1783989803","url":"https:\/\/atticusgoods.com\/products\/ronstan-series-40-orbit-ball-bearing-sheave-rf48000-for-marine-and-rigging-applications","provider":"Atticus Goods","version":"1.0","type":"link"}
