This double row angular contact ball bearing carries the internal geometry as a matched pair, taking combined radial and axial loads from both directions within a single unit. Bore diameter is 45.0 mm, outside diameter 100.0 mm, width 39.7 mm, and net mass 1.34 kg. The X-life design (XL) provides an optimized internal layout compared to standard execution, and the limiting speed is rated at 5500.0 1/min. The bearing uses a solid plastic cage (TVH) that guides the balls with low friction and supports the higher speed rating. Both sides are fitted with seals (2HRS), keeping lubricant in and contaminants out, so the bearing can run without external resealing under normal conditions. The C3 internal clearance suits applications with thermal expansion of the shaft during operation, and the double row arrangement gives stable axial guidance in both directions without needing a second bearing for counter-support.
