Style: Rubber Sealed on Both Sides Material: Chrome Steel Size: 8x22x7mm Static Load Rating: 1.35 kN/300 lbs Dynamic Load Rating: 3.3 kN/700 lbs Max RPM: 34000 ABEC Rating: C3 Quantity Per order: 20 Pieces Product Description: This sealed ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. It is made of chrome steel material which makes it durable and resistant to deformity under heavy loads. This bearing is brand new and pre-lubricated/greased from the manufacturer so no additional lubrication is required. The rubber seals on both sides of the bearing keep lubricant in and contaminants out. This deep-groove sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. It is used in a wide range of applications such as agricultural machinery, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, aggregate crushers and many other industries.
