6316C3 Single Row Deep Groove Ball Bearing C3 Enlarged Internal Clearance 80x170x39mm High Temp Fan Heavy Industrial Equipment

The 6316C3 single row heavy-duty deep groove ball bearing features C3 enlarged internal clearance, standard dimension 80×170×39mm. The 6300 series large steel ball structure delivers outstanding radial load capacity and accommodates slight bidirectional axial load simultaneously. C3 extra clearance reserves sufficient expansion space under long-hour high-speed & high-temperature operation, effectively eliminating seizure risk caused by ring thermal expansion. Open structure supports separate assembly of ZZ metal dust shield or 2RS rubber seal, widely applied in large industrial motors, heavy cooling fans, mining conveyors, cement equipment and high-load transmission shafts running under elevated temperature.

• C3 enlarged clearance: extra internal gap absorbs thermal expansion of inner & outer rings, prevents jamming under continuous high temperature & high speed
• 6300 series oversized steel balls provide much higher load capacity compared with 60/62 series bearings of identical bore size
• Ultra-precision superfinished raceway and steel balls ensure low vibration, stable smooth rotation under sustained heavy load
• Fully quenched high-hardness bearing steel offers excellent wear resistance for dusty, high-temperature harsh industrial environments
• Multiple interchangeable variants: open 6316C3, dust-proof ZZ shielded 6316C3ZZ, splash-proof sealed 6316C3-2RS
• Open design allows convenient on-site grease replenishment to extend service life for round-the-clock operating equipment
