Product Overview: The 22209 Spherical Roller Bearing
The 22209 Spherical Roller Bearing is a high-capacity, self-aligning bearing designed for the most demanding industrial applications. With key dimensions of 45x85x23mm, this bearing is a crucial component in our 22200 Series, part of the broader Spherical Roller Bearings collection. Its innovative design features two rows of symmetrical barrel-shaped rollers and a common sphered raceway in the outer ring. This construction allows the bearing to tolerate significant angular misalignment of the shaft relative to the housing, as well as shaft deflection during operation, without compromising performance.
Engineered to handle very heavy radial and axial loads in both directions, the 22209 is manufactured from high-grade bearing steel for maximum durability and service life. It is the go-to solution for machinery operating in harsh environments where shock loads, vibration, and misalignment are prevalent. For robust and reliable performance, explore our full range of spherical roller bearings.
Features of the 22209 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment and shaft deflection, reducing stress on the bearing and extending machine life.
- High Load Capacity: The double-row roller design provides excellent capacity for both heavy radial and axial loads, making it suitable for heavy-duty applications.
- Robust Construction: Manufactured from premium, clean bearing steel to withstand shock loads, vibration, and harsh operating conditions.
- Low-Friction Operation: The roller and raceway geometry is optimized to minimize friction and heat generation, leading to greater operational efficiency.
- Dimensional Stability: Precision-engineered to industry standards for consistent and reliable performance.
- Accommodates Tapered Shafts: Often available with a tapered bore (designated with a 'K' suffix) for mounting with an adapter sleeve on cylindrical shafts.
Applications of 22209 Bearings
