This single row deep groove ball bearing carries a bore diameter of 80.0 mm, an outside diameter of 170.0 mm, and a width of 39.0 mm, with a net mass of 3.75 kg. It is fitted with metal shields on both sides and uses a steel sheet metal cage (JN). Radial internal clearance is in the CN (Group N) range. The limiting speed is 4550 1/min, with a reference speed of 5500 1/min. Dimensionally and constructionally equivalent to SKF 6316-2Z, NSK 6316ZZ, and NTN 6316ZZ. The shielded design protects the raceway and balls from contact with dust and coarse particles while retaining the internal grease fill, making this bearing suited for applications where relubrication access is limited. The standard CN clearance and JN cage support balanced radial load distribution at the stated speed ratings, and the deep groove raceway geometry allows the bearing to accommodate moderate axial loads in both directions in addition to radial loads.
