The Harowe™ R25 heavy-duty brushless resolvers are designed for reliability in adverse operating conditions. Resolvers are the better choice over encoders for applications that involve very high temperature, vibration and shock and/or dirty environments. R25s will quickly recover their cost by eliminating frequent downtime caused by less robust transducers. You can trust the R25 to operate reliably 24 hours a day, 365 days a year in the worst industrial environments.

Additional Information

N/A Unlike similar duplex-bearing packages, the R25 uses a front-and-rear bearing arrangement. This provides from two to three times the radial load bearing capacity and up to ten times the L10 life of a package with duplex bearings. The increase in load bearing capacity applies equally to static, dynamic, and shock loading.
