AMI Bearings UCFL205C4HR5 High Temperature Flange Mount Bearing Unit

AMI UCFL205C4HR5 is a 25 mm bore, two-bolt oval-flange mounted ball bearing unit engineered for high-temperature service. The UCFL designation identifies a flange-mount bearing unit with an oval flange and a 2-bolt mounting footprint, while the C4HR5 configuration specifies a radial clearance class of C4 and a high-temperature rating up to 400°F (about 204°C). It employs a ball bearing insert with double-sealed (contact) seals and a setscrew locking collar for secure inner-race fixation, and it typically rides in a cast-iron housing with steel components inside. The unit’s 25 mm bore and standard 2-bolt flange simplify mounting on flat surfaces and enable reliable alignment in industrial equipment such as conveyors and drive assemblies that operate under elevated temperatures. Some catalogs note high-temperature lubrication, with certain listings indicating grease such as Super Lube No. 3, to sustain performance in demanding conditions. With an operating window extending to roughly 200°C (ambient), the UCFL205C4HR5 provides sealed, low-maintenance rotation in environments where conventional bearings may falter, making it a compact, readily serviceable solution for high-temperature machinery requiring precise alignment and dependable load handling.
