The DAC3870 RICH is a high-quality double row angular-contact ball bearing, precisely engineered to accommodate both radial and axial loads in both directions. This type of bearing is particularly well-suited for applications demanding high rigidity and accurate shaft guidance, thanks to its angular contact geometry that ensures superior performance under combined loading conditions. It features a C3 clearance, indicating that it has a radial internal clearance greater than normal, which can be beneficial for applications involving thermal expansion or potential misalignment. Equipped with double-sided non-contact shields, it offers protection against larger contaminants while allowing for slightly higher operating speeds compared to contact seals. The shields help to retain the internal lubrication, contributing to reliable performance. Its dimensions are a 38 mm bore diameter, 70 mm outer diameter, and a width of 38 mm. It has a weight of 0.584 kg. This product is manufactured in China by RICH.
