6009‑2RS1/C3 Double Lip Contact Rubber Sealed Bearing 45×75×16mm C3 Clearance High Temp Motor Pump Transmission Bearing

The 6009‑2RS1/C3 single row light series deep groove ball bearing combines double-sided 2RS1 lip contact NBR rubber seals and C3 increased radial clearance. The expanded internal clearance compensates thermal expansion of shafts and bearing rings under continuous high-speed, high-temperature operation to avoid bearing seizure failure. Double contact rubber seals tightly retain internal grease and block dust, water mist and industrial pollutants, greatly extending maintenance cycles. Widely applied to heat-generating medium-large industrial motors, water pumps, cooling fans, garden machinery, textile equipment and automation transmission assemblies with sustained operating heat.

1. C3 oversized radial clearance eliminates jamming risks caused by thermal expansion under high rotating speed and elevated working temperature, perfect for heat-generating equipment
2. Double-sided 2RS1 lip contact rubber seals deliver outstanding dustproof and splash-proof performance, prevent grease leakage and prolong grease service cycle
3. Superfinished inner and outer raceways reduce rotational friction torque, ensuring stable low-noise, low-vibration long-term continuous running
4. Light series structure with strong radial load capacity, capable of bearing slight bidirectional axial loads for all kinds of general industrial machinery
5. High-hardness GCr15 chrome steel rings and steel balls offer superior wear resistance and long service lifespan
6. Custom precision grades (ABEC1/ABEC3), special high-temperature lubricating grease and OEM personalized processing fully supported
