What Arrow Gear Company does

Arrow Gear Company, founded in 1947 by James J. Cervinka and Frank E. Pielsticker and headquartered in Downers Grove, Illinois, is a privately held precision gear manufacturer owned by Precision Arrow Gear Group (PAGG LLC). The company specializes in aircraft-quality hardened and ground gears, with spiral bevel gears as its founding and flagship product category. It produces bevel, spur, and helical gears, curvic couplings, and complete gear drives, and operates a full in-house manufacturing stack spanning design, CNC machining, heat treatment, isotropic superfinishing (capable of 2 Ra finishes), and CNC gear inspection. Equipment includes Gleason Phoenix 600 tooth cutting and grinding systems, a Hofler Rapid 800 grinder achieving 0.5 micrometer involute accuracy, a Wenzel WGT 500 bevel gear inspection system, and proprietary robotic chamfering systems. The company is certified to ISO 9001:2015, AS9100 Rev D, and Nadcap (Heat Treating, Chemical Processing, Non-Destructive Testing).

Arrow's business model is B2B custom precision manufacturing with RFQ-driven, quote-based pricing for custom gears and multi-year program contracts with aerospace and defense primes, complemented by a stock-gear catalog (51 lapped spiral bevel sets and 8 ground tooth sets in standard ratios). The company sells exclusively through direct enterprise field sales — RFQ forms, direct phone engagement, and facility visits — with no third-party distribution. Revenue streams include custom gear manufacturing, stock gear sales, gearbox assembly (capability introduced in the late 1980s via Joint Strike Fighter and F22 prototype work), and ancillary precision machining services such as CNC turning, broaching, ID/OD grinding, lapping, and inertia welding. Primary customer segments are aviation and aerospace (engines, transmissions, fixed-wing applications), government and defense (military engines and transmissions), and helicopter industry (main gears and drive-shaft bevel gears), with secondary exposure to UAV/satellite, industrial, mining, robotics, oil and gas, agriculture, food processing, and medical equipment. Named programs include Joint Strike Fighter and F22 Raptor prototypes; Arrow claims to supply more loose gears for jet engines than any other gear company. A 20,000 sq/ft Heat Treat Center of Excellence is currently under construction at the Downers Grove campus.
