Product Overview: The 3782/20 Tapered Roller Bearing
The 3782/20 is a high-performance, single-row inch series Tapered Roller Bearing, engineered to handle both radial and axial loads simultaneously. This bearing consists of two main separable parts: the cone (inner ring, rollers, and cage assembly) and the cup (outer ring). Its dimensions are a 44.45mm bore diameter, an 82.931mm outer diameter, and a total width of 24.605mm. The separable design simplifies mounting and allows for precise clearance or preload adjustments during installation, making it a versatile choice for a wide range of demanding applications.
Manufactured from high-quality bearing steel, the 3782/20 ensures durability and reliable performance under heavy loads and harsh conditions. Its tapered roller design minimizes friction and heat generation, contributing to a longer service life and improved operational efficiency. This bearing is a staple in automotive, industrial, and agricultural machinery where robust performance is critical.
