This double row angular contact ball bearing carries axial loads in both directions within a single unit, using a two-point contact design with a defined contact angle for combined radial and axial loading. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 17.5 mm, and net mass 0.091 kg. The limiting speed is rated at 19400 rpm, with a reference speed of 16600 rpm, reflecting the X-life design and reduced running friction. The bearing uses a TVH cage made of glass-fibre reinforced polyamide, which lowers mass and friction while allowing higher rotational speeds compared to a standard cage. The C3 internal clearance compensates for thermal expansion and interference fit effects during operation, keeping the bearing free of excessive preload. The double row arrangement gives stiff axial guidance in one compact width, suitable for shaft positions requiring precise axial location without a separate second bearing.
