33118

The 33118 tapered roller bearing is a high-precision metric series component designed to manage significant radial and axial loads simultaneously. Featuring a 90mm bore, 150mm outside diameter, and a total width of 45mm, this single-row bearing consists of four essential elements: the inner ring (cone), the outer ring (cup), tapered rollers, and a durable pressed steel cage. Its separable design allows the cone assembly and cup to be mounted independently, simplifying the installation process and maintenance routines in complex machinery. Engineered for stability, the 33118 excels in applications where rigid shaft guidance is critical, often utilized in pairs to handle bidirectional thrust efficiently.

Built from premium-grade chrome steel (GCr15), the 33118 bearing is optimized for long service life and high operational reliability under harsh conditions. With a dynamic load rating of approximately 310 kN and a static capacity reaching up to 390 kN, it is perfectly suited for heavy-duty sectors, including automotive transmissions, axle systems, and industrial gearboxes. The internal geometry is precision-ground to minimize friction and heat generation, supporting limiting speeds of up to 4,300 RPM under oil lubrication. Whether integrated into construction equipment or mining machinery, this bearing ensures smooth rotational performance and high fatigue resistance, making it a cost-effective solution for demanding mechanical environments.
