Product Description
The 350222X2 (GOST current designation) is a Compact Double Row Tapered Roller Bearing with boundary dimensions of 110×200×92mm, featuring an exceptionally high static-to-dynamic load ratio (Cor/Cr = 1.24) — reflecting outstanding shock load resistance and excellent combined radial-axial load handling capability.
Cross-referenced as 97222E under the original GOST designation system, this bearing belongs to the 3502xxX2 compact series — a specialized GOST family designed to deliver full heavy-duty load capacity within a significantly reduced axial width compared to the standard 3522xx series.
The 350222X2 is specifically engineered for applications where 110mm shaft diameter and 200mm housing bore are fixed constraints, but axial installation space is limited. At 8.4 kg and 92mm width, it is nearly 50% lighter and 26% narrower than the standard 352222 (16.4kg, 125mm) — while maintaining the identical Cr=410kN / Cor=510kN load ratings. This makes the 350222X2 the definitive choice for compact gearbox designs, retrofits, and space-constrained industrial machinery requiring full heavy-duty 110mm bearing performance.

✅ Double Row Tapered Roller Design — Simultaneously handles heavy radial loads AND bidirectional axial loads in both directions, ideal for shaft applications with combined loading
✅ Cr=410kN / Cor=510kN — Full heavy-duty load capacity with Cor/Cr=1.24, providing exceptional resistance to shock loads and sudden overloads typical in mining and rolling mill startup conditions
✅ Compact Axial Design (B=92mm vs 125mm standard) — 26% narrower than the standard 352222, enabling installation in space-constrained housings without sacrificing load capacity
✅ Lightweight at 8.4kg (vs 16.4kg standard) — Nearly 50% lighter than the standard 352222 with identical load ratings, reducing machine weight and simplifying installation/maintenance
✅ 110mm Bore / 200mm OD / 92mm Wide — Compact envelope for 110mm shaft installations requiring full heavy-duty performance in limited axial space
✅ 1,100/1,400 rpm Limiting Speed — Suitable for heavy industrial applications with moderate rotational speeds
✅ HRC 60–64 Hardness — Premium GCr15/52100 chrome steel with precisely controlled hardness for exceptional wear resistance and fatigue life under extreme loading
✅ Severe-Duty Engineered — Designed specifically for high loads, severe misalignment, contaminated environments, shocks, and vibrations per GOST heavy-duty standards
✅ Multi-Clearance & Precision Options — C0~C5 clearance and P0~P2 precision grades available to suit diverse application requirements
✅ Open / Shielded / Sealed Variants — Flexible sealing configurations for clean, dusty, or wet operating environments
✅ Full Interchangeability — Compatible with SKF, FAG, Timken, NSK same-dimension equivalents for seamless maintenance replacement
