This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets, with a bore of 100.0 mm, outside diameter of 140.0 mm, and width of 20.0 mm. Net mass is 0.824 kg, and the limiting speed reaches 20000 1/min. The cage is executed in version T, and the bearing is supplied without sealing, matching the open design typical for this application. The restricted tolerances place this bearing in a precision class suited for spindle arrangements requiring accurate running and controlled preload. Since it is intended for use in pairs or sets rather than as a single unit, axial internal clearance is set through the adjusted configuration rather than through an internal clearance class. The absence of sealing means lubrication and contamination control must be provided externally, and the T cage supports stable guidance of rolling elements at the stated limiting speed.
