Design Features
Optimized Load-Bearing Structure
The 240 Series utilizes wide rollers and raceways, increasing the effective contact area to achieve a high load rating. Manufactured from high-carbon chromium bearing steel (GCr15), its inner and outer rings undergo precision machining and heat treatment to ensure dimensional stability and structural integrity under heavy loads.
Dynamic Self-Alignment & Adaptability
The spherical outer ring raceway and double row of symmetrical rollers grant the bearing self-aligning capability. This allows it to compensate for minor misalignments between the shaft and housing caused by deflection or installation, promoting even load distribution and extending service life in demanding applications.

Technical Note: The cage is a critical bearing component. CA Type (Copper Alloy) cages are suited for higher speeds and temperatures; CC Type (Steel) cages offer high strength for heavy loads; MB Type (Machined Brass) cages provide smooth operation for precision applications. Standard bearings include an outer ring lubrication groove and holes (W33). For specific cage availability and custom configurations, please inquire.
