Part Number 23156EJW507C08, Spherical Roller Bearings

Key Features

• Longer bearing life achieved from higher capacity (vs. competitors)

• Longer lubrication life achieved from lower operating temperatures due to reduced internal friction and running torque from cage guided rollers

• Better contaminant purging from slots on cage face helps extend bearing life

• Greater fatigue strength and increased wear resistance provide tougher protection against shock and acceleration loading from a hardened steel cage
