Single row angular contact ball bearing with 12.0 mm bore, 32.0 mm outside diameter and 10.0 mm width, mass 0.035 kg. It is fitted with a solid plastic cage (TVP), part of the X-life design line, which allows a limiting speed of 33000 1/min and a reference speed of 21100 1/min. The angular contact design carries combined loads and requires axial preloading or pairing to take up thrust from both directions. The plastic TVP cage keeps ball spacing stable at speed and contributes to low friction operation, supporting running at the higher limiting speed value stated. As supplied without integrated sealing, lubrication and contamination protection must be provided externally, so grease or oil supply should be selected according to the actual operating speed and environment.
