33016 3007116E 33016R Chrome Steel 80*125*36mm Single Row Cone and Cup Tapered Roller Bearings

The 33016 (standard model), 3007116E (legacy model), and 33016R (KOYO-specific model) single row tapered roller bearings are manufactured from high-grade 52100 chrome steel (equivalent to GCr15). Through precision heat treatment, the material achieves a hardness of HRC 58-62, delivering three critical performance benefits tailored to compact heavy-duty applications with an 8012536mm footprint (80mm ID, 125mm OD, 36mm width):
Wear Resistance: Outperforms low-carbon steel bearings by 320-330% in dusty, heavy-industrial environments (e.g., large machine tool spindles, 20-30kW motor shafts, medium-sized transmission gearboxes). It effectively resists particulate abrasion that typically shortens the service life of standard bearings.
Impact Toughness: Absorbs sudden load spikes—such as start-stop cycles of heavy conveyors or vibration from industrial-grade precision equipment (e.g., CNC milling centers)—without micro-cracking or deformation, ensuring stable operation in high-cycle heavy-duty scenarios.
Basic Corrosion Protection: When paired with standard anti-rust treatments (e.g., anti-corrosion oil coating, passivation), it resists rust in humid environments (e.g., workshop air compressors, small hydraulic power units), reducing replacement costs for high-power drivetrains.
Ideal for 20-30kW electric motors, medium gearboxes, and heavy-duty precision components, these bearings extend service life to 18,000-20,000 operating hours, significantly reducing maintenance frequency for compact industrial equipment under heavy loads.
