| Deep groove ball bearing with seals or shields | |||||||||
Deep groove ball bearing with seals or shields Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. Integral sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed makes radial and axial load in both directions, so it requires little maintenance. |

SKF 61921 deep groove ball bearing Key Features: Deep Groove Design: This design is characterized by its deep raceway grooves, allowing it to carry a high radial load capacity and enabling it to operate at higher speed. Single Row: This bearing is typically a single-row ball bearing, which makes it suitable for various applications where space is limited but reliable performance is needed. Low Friction: SKF bearings are known for their low friction, contributing to higher efficiency and longer service life. Versatile: It's a versatile bearing type that can be used in a wide range of applications, from industrial machinery to electric motors, automotive components, and more. Standard Seals: SKF 61921 bearings often come with seals (either non-contact or contact seals) to protect the bearing from dirt, dust, and moisture, which extends the lifespan of the bearing. Specifications: Inner Diameter (ID): 105 mm Outer Diameter (OD): 145 mm Width (B): 20 mm Dynamic Load Rating (C): Typically around 48 kN (check exact specs based on specific SKF series) Static Load Rating (C0): Typically around 23.5 kN Grease Lubricated: Most variants come pre-lubricated, though oil lubrication can also be an option in some applications. Applications: Electric Motors: Used in electric motor assemblies due to their ability to support both radial and axial loads while minimizing noise and vibration. Pumps and Compressors: The deep groove design helps manage high-speed rotation and varying loads in pump applications. Automotive: Suitable for car components like alternators, wheel hubs, or gearboxes. Machinery: Found in both industrial and agricultural machinery where reliability and high performance are key. | |||||||||
