8MSA4L.E0-31
The B & R Automation 8MSA4L.E0-31 component from the 8MS Three Phase Synchronous Motors series is a robust steel synchronous motor gear ring featuring module 4 and 31 teeth for uniform load distribution. Its 132 mm outside diameter and 124 mm pitch diameter ensure compatibility with standard mounting envelopes and precise belt engagement, while the 40 mm face width enhances durability under cyclic forces. The pilot bore enables concentric shaft alignment and, with no keyway, reduces stress concentrations. Treated with a nitride surface, the case hardness reaches up to 1400 HV, improving wear resistance in abrasive environments. Complying with DIN 3960 accuracy standards and weighing 4.2 kg, this unit combines high tensile strength and precise 31° helix angle engagement to minimize noise and vibration, making it ideal for demanding industrial automation applications.
