Versatile, cost-effective ER bearings feature a design with an extended inner ring to allow for adapter-free mounting. These rings provide extra shaft support, making ER bearings a popular choice for demanding industries such as construction, packaging, textiles, and conveyance.
Emerson Bearing stocks ER free running inserts in multiple styles. The free running style is a specialized type of ER bearing insert, offering low torque service. We designed these inserts for harsh industrial environments, with flingers built on both sides of the bearing for complete sealing. ER free running inserts operate in extreme temperatures, including -40 to 225°F for standard units and up to 400 to 450°F for high-temperature seals.
Our free running inserts are available in a range of sizes, from 1.8504” by 1.2188” to 3.3465” by 1.9370”. These units cover shaft diameters from 0.5” through 1.5625”, basic loads from 2.740 lbs. through 7.110 lbs., and basic static loads from 1.600 lbs. through 4.460 lbs.
