Product Details
SKF Roller Bearing, 120mm OD, 55mm ID, 7500r/min Limiting Speed, 166kN Static Load Rating - 21311E
Keep your machine's rotating parts moving fluidly with this roller bearing from SKF. It's designed to handle heavy loads in both radial and axial directions, so it's a handy choice for demanding industrial applications. As the sheet metal cage withstands corrosion and impact, you can count on a long lifespan even in tough settings. This device is self-aligning, so it can tolerate misalignment between its shaft and housing without a significant increase in friction. The double-row design means it supports substantial loads without giving in to fatigue.
Features & Benefits
• Limiting speed of 7500r/min to suit high-speed rotating machinery
• Static load rating of 166kN and dynamic load rating of 156kN so it's suitable for use with heavy-duty equipment
• Cylindrical bore means it's easy to align with the shaft for simple installation and disassembly
• Static load rating of 166kN and dynamic load rating of 156kN so it's suitable for use with heavy-duty equipment
• Cylindrical bore means it's easy to align with the shaft for simple installation and disassembly
Applications
• Conveyor systems
• Mining equipment
• Aerospace technology

What's the difference between reference speed and limiting speed?
The bearing's reference speed is a practical limit under which it can operate smoothly without overheating. The limiting speed is the maximum speed at which it can function mechanically without experiencing damage.
