Product Description
The 352217 (GOST current designation) is a Double Row Tapered Roller Bearing with boundary dimensions of 85×150×85mm, featuring an exceptionally high static-to-dynamic load ratio (Cor/Cr = 1.24), which reflects outstanding shock load resistance and suitability for high-speed, high-load applications.
Cross-referenced as 97517E under the original GOST designation system, this bearing belongs to the heavy-duty 3522xx series and is specifically engineered for the most demanding industrial environments — including applications with severe misalignment, contamination, vibration, and impact loading. Its unique square cross-section (B/d = 1.000, B = d = 85mm) makes it instantly recognizable and particularly well-suited for compact, symmetrical shaft housing designs.
At only 5.67 kg with limiting speeds of 1,700 rpm (grease) / 2,000 rpm (oil) — the highest speed rating in the entire 3522xx series — the 352217 achieves a truly remarkable engineering balance: delivering the same full Cr=410kN / Cor=510kN load capacity as bearings weighing up to 120kg+, in the most compact, lightweight, and highest-speed package in the family.

✅ Double Row Tapered Roller Design — Simultaneously handles heavy radial loads AND bidirectional axial loads, ideal for shaft applications with combined loading
✅ Cr=410kN / Cor=510kN — High static-to-dynamic ratio (Cor/Cr=1.24) provides exceptional resistance to shock loads and sudden overloads typical in mining and rolling mill startup conditions
✅ Unique Square Cross-Section (B=d=85mm, B/d=1.000) — Symmetrical geometry simplifies housing design and provides balanced load distribution across both roller rows
✅ 85mm Bore / 150mm OD / 85mm Wide — Ultra-compact envelope ideal for space-constrained 85mm shaft installations requiring maximum load capacity at high speeds
✅ 1,700/2,000 rpm Limiting Speed — Highest speed capability in the entire 3522xx series, suitable for higher-speed heavy-duty applications including industrial gearboxes, rolling mill drives, and mining equipment
✅ Ultra-Lightweight at 5.67 kg — Lightest member of the 3522xx family, enabling the easiest handling, installation, and maintenance while maintaining full Cr=410kN / Cor=510kN load capacity
✅ 52100 / GCr15 Premium Chrome Steel — High-grade bearing steel offering exceptional hardness (HRC 60–65), 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
