Key Specifications & Why BDL Needle Roller Bearings Stand Out

Description Core Value
Model Range K20×24×17 to K25×30×20 — ultra-compact radial design for space-constrained machinery
Load Direction Pure radial load capacity with high L/D ratio — ideal for oscillating & intermittent motion
Design Style Ringless (no inner/outer ring) — reduces weight, simplifies assembly, lowers cost vs. full-complement types
Material High-carbon chromium bearing steel (GCr15 equivalent) — hardened to HRC 60–64 for extended fatigue life
Precision & Clearance Available in P0–P2 tolerance grades and C0/C3/C4 clearances — ensures smooth operation under thermal expansion
Lubrication Pre-greased or oil-lubricated — compatible with standard industrial lubricants; low-maintenance operation
Origin & Compliance Manufactured in ISO 9001-certified Chinese facilities; HS Code 8482102000 — fully customs-compliant
Applications Automotive transmissions, gearboxes, agricultural equipment, textile machinery, and compact actuators
Quality Assurance 100% dimensional inspection + noise & rotation testing — meets SKF-compatible performance benchmarks
Why Choose BDL Over Alternatives? 20% higher dynamic load rating vs. generic equivalents; OEM-grade consistency; fast 3–7 day delivery from stock

Frequently Asked Questions:
Q: Are these interchangeable with SKF HK/K series? A: Yes — identical dimensions and load ratings; direct replacement.
Q: Can they operate at high speeds? A: Optimized for moderate speeds (≤8,000 rpm); consult engineering team for high-RPM applications.
Q: Do you support custom packaging or labeling? A: Yes — white-labeling and OEM branding available upon request.
