SKF 6316-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 80x170x39mm

The SKF 6316-2RS1/C3 sealed deep groove ball bearing provides substantial radial load support for equipment with an 80mm shaft and a 170mm bearing housing bore. Its 39mm width and robust single row construction make it suitable for demanding industrial drives where both bearing capacity and reliable shaft guidance are important. Deep groove raceways accommodate predominantly radial loads together with axial forces in either direction, subject to the bearing's rated limits. SKF specifies a 130kN basic dynamic load rating and an 86.5kN basic static load rating, making these figures important when assessing fatigue life, peak loading and machinery duty cycles. The bearing uses a pressed steel cage and conventional cylindrical bore for standard shaft mounting arrangements.

The 2RS1 contact seals are fitted on both sides to retain factory-applied grease and help prevent moisture, dust and other contaminants entering the rolling elements. The C3 clearance suffix identifies greater radial internal clearance than the normal CN version, providing additional allowance where tight shaft fits or temperature differences reduce clearance during operation. C3 should nevertheless be selected according to the equipment manufacturer's requirements rather than assumed necessary for every heavy-duty application. SKF lists a 2,600rpm limiting speed for this sealed bearing; actual operation must also consider seal friction, loading, lubrication and heat dissipation. For replacement work, confirm the full 6316-2RS1/C3 designation, correct mounting fits and available housing space. Never transmit installation forces through the rolling elements.
