This four-point contact bearing carries combined radial and axial loads in both directions through a single row of balls contacting the grooves at four points. Bore diameter is 35.0 mm, outside diameter 80.0 mm, width 21.0 mm, and net mass is 0.56 kg. The bearing is fitted with a solid brass cage (MPA) and rated C3 internal clearance. Limiting speed reaches 17900 1/min, with a reference speed of 7200 1/min. Because a single row handles axial loads from both sides, this design suits shaft arrangements requiring axial location without a second bearing for opposite-direction thrust. The C3 clearance compensates for thermal expansion during operation, while the solid brass cage supports stable ball guidance at the stated speed range. The construction allows mounting where both radial and bidirectional axial forces act on the same bearing position.
