Feature:_x000D_ _x000D_ This sealed ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. _x000D_ It is made of 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. _x000D_ The rubber seals on both sides of the bearing keep lubricant in and contaminants out. _x000D_ 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. _x000D_ Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. _x000D_ _x000D_ _x000D_ Specification: _x000D_ Model(Optional) Inner diameter Outside diameter Thickness _x000D_ 623-2rs 3mm 10mm 4mm _x000D_ 624-2rs 4mm 13mm 5mm _x000D_ 625-2rs 5mm 16mm 5mm _x000D_ 626-2rs 6mm 19mm 6mm _x000D_ Cage material: Steel plate _x000D_ Application: General_x000D_ Number of rolling body columns: Single column_x000D_ Raceway type: Deep groove raceway_x000D_ Bearing material: Bearing steel_x000D_ Rolling body type: Ball_x000D_ Angle: 15 degrees_x000D_ Sealing cap: Double-sided seal_x000D_ Rolling body: Steel ball_x000D_ _x000D_ Package list:_x000D_ 10 * Ball Bearings_x000D_ _x000D_ Note:_x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
