Technical Specification .webp "32209 7509E Metric Tapered Roller Bearings")
.webp "diagram of dsbr metric tapered roller bearings (2)")
The 32209 7509E tapered roller bearing is designed to handle both radial and axial loads with high efficiency, making it ideal for heavy-duty applications such as automotive axles, gearboxes, trailers, and agricultural machinery. Manufactured using high-grade bearing steel (GCr15/52100) and processed through advanced heat treatment, the 32209 7509E offers superior fatigue resistance, load-bearing capacity, and dimensional stability under demanding conditions.
Its precision-ground raceways reduce friction and vibration, ensuring smooth rotation and quiet performance at high speeds. The separable inner and outer ring structure allows for easy installation, inspection, and maintenance. This bearing is commonly used in truck and trailer wheel hubs, where reliability under impact load is critical.
DSBR offers OEM customization, including pre-lubrication, packaging, and preload settings, with ISO 9001 & IATF 16949 certified production quality. Whether you're sourcing for replacements or mass production, DSBR provides stable supply and competitive pricing.
Ideal for heavy-duty applications, they offer:
Excellent capacity for both radial and axial forces
Support for axial loads in a single direction
Reduced friction for efficient, high-speed operation
Durable, replaceable, and service-friendly design
