Product Description
The 352216 (GOST current designation) is a Double Row Tapered Roller Bearing with boundary dimensions of 80×140×80mm, featuring a dynamic load rating of 320 kN and static load rating of 315 kN, with limiting speeds of 1,800 rpm (grease) / 2,400 rpm (oil) — the highest oil-lubrication speed rating in the 3522xx series.
Cross-referenced as 97516E 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.
The 352216 stands out within the 3522xx family for its perfectly square cross-section (B = d = 80mm, B/d = 1.000) — shared only with the 352217 — and its 2,400 rpm oil-lubrication speed, the highest in the entire series. At only 4.97 kg, it is the absolute lightest member of the 3522xx family, making it the premier choice for compact, high-speed, high-load 80mm shaft applications where installation space, weight, and rotational speed are all critical constraints.

✅ Double Row Tapered Roller Design — Simultaneously handles heavy radial loads AND bidirectional axial loads, ideal for shaft applications with combined loading
✅ Cr=320kN / Cor=315kN — Balanced radial and axial load capacity with near-unity Cor/Cr ratio (0.984), optimized for applications with balanced combined loading rather than pure shock resistance
✅ Perfectly Square Cross-Section (B=d=80mm, B/d=1.000) — Symmetrical geometry simplifies housing design, provides balanced load distribution across both roller rows, and minimizes axial installation space
✅ 80mm Bore / 140mm OD / 80mm Wide — Ultra-compact envelope ideal for space-constrained 80mm shaft installations requiring high load capacity at high speeds
✅ 1,800/2,400 rpm Limiting Speed — Highest oil-lubrication speed (2,400 rpm) in the entire 3522xx series, suitable for the most speed-critical heavy-duty applications
✅ Absolute Lightest at 4.97 kg — Lightest member of the entire 3522xx family, enabling the easiest handling, installation, and maintenance
✅ 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
