SKF Deep-groove Ball Bearing, Plain Race Type, 20 mm ID - 61804-2RS1 This ball bearing from SKF is a low-maintenance option for machinery that needs to handle both radial and axial loads. Thanks to rubber seals that keep dirt out of the bearing and lock the lubricant in, it's a reliable unit that you won't need to re-grease. The bearing is made entirely from steel to improve its durability and lifespan. It produces low levels of friction and won't overheat, making it suitable for use with machinery that operates at high rotational speeds. • Parallel bore type

• Food and beverage industries How does the roller bearing work? A roller bearing is a precision machine element that positions and supports rotating equipment. It minimises friction and noise, which reduces the need for maintenance of a machine's moving parts. Why is the bearing's initial clearance usually greater than its operating clearance? The bearing's operating clearance accommodates the thermal expansion of the bearing's parts as it reaches its operational temperature.
