What Optibelt AG does

Optibelt AG is the Swiss sales entity of the Arntz Optibelt Group, a 154-year-old family-owned German industrial group founded in 1872 in Höxter, Westphalia, and one of the world's leading manufacturers of high-performance drive belts and power transmission components. The company manufactures V-belts (optibelt RED POWER 3, BLUE POWER 2, SUPER XE-POWER PRO), timing belts (OMEGA, ALPHA, DELTA CHAIN), ribbed belts, Kraftbands, polyurethane conveyor belts, elastomer sheeting for sealing, damping and X-ray protection, and accessory components including tension and idler pulleys, repair kits and air springs. Its flagship technical assets include patented tension-cord engineering (aramid, polyester and carbon cords), EPDM compound reinforcement with transverse fibres, and the patented optibelt Modular Cleat System (MCS) for material-handling applications. Headline products are validated for up to 97% drive efficiency (BLUE POWER 2) and 5–10% energy savings versus conventional belts.

The Arntz Optibelt Group generates revenue through B2B hardware sales of drive belts and engineered solutions, with €284 million in FY2024 turnover, slightly below the prior year due to sluggish industrial conditions and a late-summer 2024 cyber-attack. The go-to-market combines direct enterprise sales through approximately 30 owned sales offices across Europe, the Americas, Asia Pacific, North Africa and Oceania with exclusive distribution through authorised specialist trade partners and an integrated e-commerce platform backed by digital engineering tools (CAP drive calculation software, TCO calculator, CAD service tool, mobile app). Customers are industrial OEMs and aftermarket accounts across more than 15 verticals, with named references including Porsche and Karmann (automotive), Claas (agricultural machinery), and bicycle OEMs via the Optibelt Mobility subsidiary founded in 2024.

Manufacturing is operated through nine production sites in seven countries (Höxter, Bad Blankenburg and Rinteln in Germany; San Juan del Río in Mexico; plus Romanian, North African and additional European capacity) and the Group employs over 2,400 people worldwide, including 70+ in North America. Ownership remains with the Arntz family through private limited companies; Regina Arning succeeded Reinhold Mühlbeyer as Managing Director/CEO on 30 November 2024.

Revenue model

1. High-performance drive belt sales: Optibelt manufactures and sells V-belts, timing belts, ribbed belts, polyurethane conveyor belts, and related components (tension pulleys, repair kits, metal products) to industrial customers worldwide. Products are sold through direct sales, specialist trade distributors, and e-commerce platform. Revenue is generated through one-time product sales with repeat purchase cycles driven by replacement needs and new project wins.
2. Industry-specific drive solutions: Optibelt develops and delivers custom drive solutions tailored to specific industry applications (automotive, agricultural machinery, food & beverage, construction, etc.), often working in close partnership with customers from analysis and design through to final optimisation. This involves technical consulting and solution engineering alongside product supply.
3. Micro-mobility drive systems: Through its subsidiary Optibelt Mobility (founded 2024), the company develops and distributes drive systems for bicycles, scooters, and motorcycles, including STX and TTX PU belt systems and sprockets. Targets both OEM manufacturers and end customers.
