Custom precision gearbox and mechanical subassembly manufacturer CGI Inc. now offers a new line of IP69K-rated precision planetary gearheads. The Raptor-SS series gearheads are washdown ready and built with advanced heat-treated materials — with stainless-steel construction or a white epoxy coating.

Raptor-SS gearheads are compact (with lengths from 3.39 in to 7.63 in) and have a captive input pinion; high-torque gear geometry; and exceptional stiffness and loading characteristics. They can mount in any direction and accept input speeds to 6,500 rpm. Service life exceeds 15,000 hours.

The IP69K-rated gearheads are available in:

• One, two or three-stage configurations (with backlash of 4, 6 and 8 arc-min respectively) to deliver speed-reduction ratios of 4:1 to 700:1 — with other ratios possible from the three-stage version
• Standard NEMA and metric configurations — and with other features for quick installationSource: CGI Inc.
• Versions with food-grade grease for food-related applications

Efficiencies are better than 95% for single-stage gearheads, 90% for two-stage gearheads and 85% for three-stage gearheads in the Raptor-SS series. Operating range is -40° F to 250° F.

Raptor-SS gearheads in 023RTX (NEMA) and 060RTX (metric) sizes deliver nominal torques of 17 to 45 nm; maximum acceleration torques of 22 to 53 nm; and peak emergency-stop torques of 81 to 107 nm. Torsional stiffness is 15 arc-min.

Raptor-SS gearheads in 034RTX (NEMA) and 090RTX (metric) sizes deliver nominal torques of 63 to 164 nm; maximum acceleration torques of 80 to 207 nm; and peak emergency-stop torques of 277 to 392 nm. Torsional stiffness is 70 arc-min.
