KA090XP0 ultra thin wall four point contact ball bearing combines extra‑large bore and KA‑series ultra‑thin equal cross‑section. It delivers high‑precision rotation under multi‑direction combined‑load environment. Widely applied for large‑diameter compact positioning turntables,special industrial rotary platforms and large automation precision assemblies.
X-type four-point contact ball bearings - KA series feature an optimized four-point contact raceway geometry with a split inner ring and single outer ring design (or vice versa), allowing compact support of radial loads while accommodating high axial loads in both directions with minimal clearance. Available in standard, thin-section, and heavy-duty configurations, with bore diameters ranging from 25mm to 400mm. These bearings deliver high axial rigidity, compact design, reliable moment load capacity, and reduced system weight, making them ideal for slewing rings, industrial robot joints, crane turntables, packaging machinery, and precision rotary tables.
