QJ209, Angular Contact Ball Bearing, Split Inner Race, Single Row, Open, 35° Contact Angle, Brass Cage, Normal Clearance, Metric, 45mm ID, 85mm OD, 19mm Width, Single-row angular contact ball bearing, supporting bidirectional thrust loads, and combined loads where thrust load is predominant. Ball contact angle of 35 degrees relative to the inner and outer raceways increases thrust load capacity. Open configuration for lubrication applied in place Brass cage evenly spaces balls for reduced friction, vibration, and noise ABEC 1 tolerance ratings for accuracy and low rotational speeds
