8MSA2L.R0-44

Product Description:

The 8MSA2L.R0-44 comes from B & R Automation and is part of the 8MS Three Phase Synchronous Motors family. It uses a three-phase design and the body measures out at a length of 1000 mm, giving it reach for equipment that needs stability and exact positioning. This model uses case-hardened steel as the core material, and the hardness checks in at 58-62 HRC—hard enough to take on repeated use with little wear showing up. At 5.4 kg, the motor fits into equipment without adding excess weight, which can help reduce strain across long machine frames.

Tolerances show up tight on this part since backlash stays at ≤ 0.04 mm and there's a straightness tolerance of ≤ 0.05 mm per meter. That much control matters especially when accuracy is tracked over longer distances in big factory lines, as it keeps errors low and finished parts reliable. The face width comes in at 20 mm, and the profile shift coefficient is x = 0, meaning gears or other interfacing equipment can bolt up without fuss or rework. Every mounting hole gets spaced at 125 mm, drilled at 8.5 mm diameter for easy and repeatable fixture alignment. Modules are rated 2 on this series for gear fit, which bumps the versatility up for uses with custom layouts.

In practice, the 8MSA2L.R0-44 slips right into high-end industrial work demanding both consistency and resilience. Built from tough, case-hardened steel, this model shrugs off mess, vibrations, and sudden temperature jolts that usually weaken lighter builds. Whether lined up for pick-and-place arms or precise conveyor drives, it stands up to cycles without constant repair stops. Most of the time, this motor just runs—quiet, low on error—letting the rest of the line keep focus on output instead of adjusting or fixing motion.
