Introduction
This self-aligning ball bearing (Model 2214K) features high precision (P0–P2), radial load capacity, and flexible clearance options (C0/C3/C4). Made of premium bearing steel with steel/brass cage, it ensures durability and smooth operation. Ideal for demanding industrial applications requiring misalignment compensation.Key Features & Technical Highlights
| Description | Core Value |
|---|---|
| Self-aligning ball bearing (Model 2214K) | Automatic heart adjustment compensates for shaft misalignment up to ±2.5° — extends service life by 40% vs. standard radial bearings |
| Double-row, unseparated design | Higher radial load capacity & inherent stability under dynamic loads |
| Bearing steel (GCr15) + precision ground raceways | Meets SKF ABEC-5 / ISO P5 tolerance standards; surface hardness HRC 60–64 |
| Grease or oil lubrication compatible | Pre-lubricated with lithium-based grease (NLGI #2); optional sealed variants available |
| Clearance options: C0/C3/C4 | C3 ideal for moderate temperature rise & heavy-duty industrial use |
| Precision grades: P0 to P2 | P5/P4 grades certified for high-speed spindles & CNC applications |
| 95×170×32 mm (d×D×B), steel/brass cage | Optimized weight-to-strength ratio; brass cage enables higher RPM and thermal stability |
| OEM/ODM supported — BDL brand (China origin, HS 8482101000) | Fully compliant with ISO 15242-2 & GB/T 273.2; RoHS & REACH certified |
| 10–15 day lead time, 1M pcs/month capacity | Fast turnaround without compromising batch traceability or 100% dimensional inspection |
| Common applications: textile machinery, agricultural gearboxes, fans, conveyors | Proven reliability in dusty, humid, and vibration-prone environments |
Why Choose This Bearing Over Generic Alternatives?
Unlike economy-grade self-aligners, this 2214K features micro-ground raceway curvature, controlled internal clearance distribution, and cage guidance geometry validated per SKF’s kinematic simulation protocols — reducing friction heat by 18% and noise by 12 dB(A). All units undergo ultrasonic cleaning, dynamic balancing, and final load testing at 10% of rated dynamic capacity.
FAQ
Q: Is this bearing interchangeable with SKF 2214 K? A: Yes — identical dimensions, tolerances, and alignment capability; full drop-in replacement.
Q: Can it handle axial loads? A: Limited axial capacity (<15% of Cr); recommend paired with thrust bearings for combined loads.
Q: What’s the max speed with grease lubrication? A: 3,800 rpm (C3, P5, steel cage); 4,500 rpm with brass cage & optimized grease.
