33205 3007205E 33205R Chrome Steel 25*52*22mm Single Row Cone and Cup Tapered Roller Bearings

Built to ISO 355/DIN 720 standards with P6-level precision (minimal vibration and misalignment), the dimensions are optimized for space-constrained small-size setups where load demands exceed typical compact bearings:
25mm Inner Diameter (ID): Fits small industrial shafts (tolerance: 0/-0.011mm) and accommodates a minimum 2mm shaft chamfer. The tight ID tolerance ensures a secure interference fit with 5-10kW motor shafts, mini CNC spindle shafts, or small seeder drive rollers—preventing slippage even under torque surges (e.g., mini lathe cutting hard metals, small mixer stirring thick materials).
52mm Outer Diameter (OD): Seamlessly integrates into compact machinery housings (compatible with a minimum 1.5mm outer ring chamfer), eliminating the need for oversized enclosures. This is critical for small pumps, mini gearboxes, or portable construction tools where space is at a premium.
22mm Width: Provides an enhanced contact area (≈20% larger than narrower small bearings of similar ID/OD) for balanced radial-axial load distribution. The width ensures even load transfer across raceways, making it ideal for small vibrating screens (for granular material sorting) or auxiliary shafts in small agricultural machinery.
CNC grinding (with a precision of ±0.004mm) guarantees dimensional consistency across batches, eliminating fit gaps that cause 95-98% efficiency loss in misaligned small heavy-duty bearings.
