This self-aligning ball bearing compensates for shaft misalignment through its spherical outer raceway, allowing the inner ring with balls to tilt relative to the outer ring. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 14.0 mm, giving the basic envelope needed for seat selection. The TVH cage is a plastic design guiding the ball set, and net mass is 0.116 kg. Limiting speed is rated at 18100 1/min, with a reference speed of 15300 1/min for thermal reference under standard conditions. Radial internal clearance is C3, wider than normal, which allows for thermal expansion and some shaft deflection without inducing preload. The Z bore type and TVH cage identify the specific execution covered by this symbol. This bearing corresponds dimensionally and constructionally to RHP 1204JC3 and SKF 1204ETN9/C3.
