KA020XP0 ultra thin wall four point contact ball bearing belongs to KA‑XP0 Reali‑Slim thin‑section bearing family with 0.25‑inch equal square cross‑section. Made of premium 52100 chrome bearing steel and fitted with brass snap‑over cage. This Type‑X four‑point contact bearing can simultaneously undertake radial loads, bidirectional axial loads and overturning moment loads. It delivers low‑friction smooth rotation with compact lightweight profile, one single bearing can replace two angular contact bearings to save installation space. Widely used for rotary tables,optical instruments,robot joints and compact precision automation equipment under strict space‑limited conditions.

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.
