AC4631

The AC4631 is a specialized double-row angular contact ball bearing designed specifically for the demanding environment of automotive air conditioning compressor clutches. Its precise construction ensures smooth engagement and disengagement of the clutch, providing reliable performance through countless cycles. This bearing is built to handle the specific combination of radial and axial loads generated by the belt tension and clutch actuation, making it a critical part for a functioning AC system.
Engineered to withstand the harsh under-hood environment, the AC4631 bearing is built for long-term durability. It typically features high-quality seals to protect against contaminants like dust, moisture, and road grime, while effectively retaining its specialized grease. This sealed design is crucial for preventing premature failure and ensures the bearing operates efficiently for an extended service life without needing maintenance.
The internal geometry of the AC4631 is optimized for high-speed, low-noise performance. As an angular contact bearing, it provides the rigidity needed to maintain pulley alignment and prevent wobble, contributing to a quieter and more efficient drive belt system. Its reliable operation helps ensure your vehicle's air conditioning runs smoothly, delivering consistent cooling performance when you need it most.
