Key Specifications & Benefits of SKF Tapered Roller Bearings (30211, 30312, 32213, 32313)
| Description | Core Value |
|---|---|
| High-Precision Tapered Design | Enables simultaneous radial & axial load handling with minimal friction and thermal expansion |
| Multiple Precision Grades (P0–P2) | P2-grade option delivers ultra-low runout for high-speed machinery and precision gearboxes |
| Low-Vibration Options (Z1V1–Z3V3) | Ensures quiet operation in HVAC systems, textile spindles, and medical equipment |
| 55×100×21 mm Standard Size | Direct OEM replacement for major industrial gearmotors and agricultural axles |
| Grease or Oil Lubrication Ready | Flexible maintenance — compatible with lithium complex, polyurea, and ISO VG 68–220 oils |
| Made in China, SKF-Compliant Engineering | Rigorous testing per ISO 15242 & DIN 6220; 100% traceable batch records |
| OEM/ODM Support | Custom packaging, laser marking, and application-specific preload tuning available |
| 1M Units Annual Capacity | Guaranteed stock availability and fast lead times — no production delays |
| HS Code 8482200000 Certified | Fully compliant for global customs clearance — zero documentation surprises |
| BDL Brand with SKF-Quality Process Control | Same heat treatment, cage geometry, and surface finish as premium-tier tapered bearings |
Engineered for demanding applications: construction machinery hubs, wind turbine yaw systems, mining conveyor idlers, and railway axle boxes. Backed by 100% dimensional & dynamic load verification (Cr, Cor, e, Y). Unlike generic imports, every batch undergoes vibration spectrum analysis and microhardness mapping. FAQ: Can these replace original SKF 30211? Yes — identical ABEC/TQB tolerances and contact angle (13°–16°). Are cages brass or steel? Both options available — specify at order. What’s the max operating temperature? 120°C continuous (grease-lubricated), 150°C intermittent.
