The NKE 4304-B-TV-C3 is a genuine NKE double row angular contact ball bearing, engineered for applications requiring high radial and axial loads. It features a 20mm bore diameter, 52mm outer diameter, and a 21mm width. This bearing incorporates a glass fibre reinforced polyamide cage (TV) and has a C3 radial internal clearance, indicating a greater than normal clearance for demanding operating conditions. With a basic dynamic load rating of 27.5 kN and a static load rating of 17.6 kN, it offers robust performance. The limiting speed with grease lubrication is 10,000 rpm, and with oil lubrication, it reaches 14,000 rpm.
