Series Overview
Verifying tooth base fatigue strength: SP – I 0229 / 3 – 04516 Drawing reference number Valid for the following conditions: - Output speed: n = 5.0 rpm Gearing heat treatment - Repeated load 1: Normalized - Ambient temperature of 68°F 3: Hardened
Raceway diameter [mm] Md B: Operation torque [ft-lbs] 229, 411, 541 and 641 mm Md nom: Nominal torque [ft-lbs] for SF = 1 and n = 5.0 rpm (see dimensions table)
I: Intermediate series If the following equation is met, the stress level Fatigue stress of tooth base needs to be considered SP: Spur gear driven type of tooth base is below the endurance limit and however, if the following equation is met (if so, refer fatigue is infinite: to below additional steps to verify life):

110 For custom configurations, we also supply material certificates according to EN 10204-3.1. B. This certificate logs the actual values of material characteristics such as tensile strength, apparent yielding point, notched bar impact work, extension and chemical analysis. Material tests are performed according to the latest industry recognized methods (i.e. ultrasonic testing- developed by the Fraunhofer Institute). EN ISO 9001:2000 certified Quality Assurance We want you to be satisfied!
IMO Slew Drives have to meet the highest quality requirements because they are often used as safety critical components. Development, design, calculation and sales are performed strictly according to EN ISO 9001:2000 certified procedures. EN ISO 9001:2000 certified Quality Assurance
The quality chain starts with the choice of the raw material (i.e. for the production of seamless rolled rings of the SP-series) and is continuous, including the ongoing testing of the current production series.
