SER Series Spherical Roller Bearings with Retaining Grooves and Set Screws feature dedicated retaining grooves and are secured with set screws, ensuring more precise positioning and a more secure axial lock, effectively preventing loosening or displacement during operation. Equipped with a reliable sealing structure, these bearings offer excellent dust and contamination resistance. They also feature self-aligning capabilities to compensate for installation errors, making them suitable for general-purpose transmission equipment with moderate to light loads that requires high axial positioning accuracy and is subject to vibration. They offer a stable structure, easy installation, and high practicality.
