Welcome to Linqing Xinshengdi Bearing Co., Ltd.
DAC42800045 Wheel Hub Bearing (42x80x45mm)
- Structural Footprint: Heavy-duty 42mm inner bore, 80mm outer diameter, and a wide 45mm axial footprint for maximum load distribution.
- Advanced Metallurgy: Vacuum-degassed, high-carbon chromium steel engineered to eliminate subsurface inclusions that trigger micro-cracking.
- Heavy-Duty Sealing: Premium multi-lip elastomeric seals engineered to withstand the extreme centrifugal pressure of highway driving.
Product Overview:The DAC42800045 is a heavy-duty, double-row angular contact ball bearing meticulously designed to handle the elevated vehicle mass and high centers of gravity typical of modern mid-size crossovers, SUVs, and utility vehicles. When a larger vehicle enters a sharp turn at speed, severe lateral moment forces are transferred directly down through the steering knuckle to the wheel bearing. A standard passenger car bearing would flex, leading to accelerated wear and brake caliper misalignment. The expansive internal ball complement of the DAC42800045 maximizes structural rigidity, ensuring absolute tracking stability under high-stress cornering loads.
To ensure long-term survivability under demanding driving cycles, DBS Bearings utilizes an optimized split inner-ring configuration. During our 100% Individual Quality Verification, the internal contact angles and ball sizing parameters are meticulously matched. This rigorous control eliminates internal stress imbalances between the twin rows of balls, providing your fleet and retail customers with a replacement part that eliminates hub play and prevents steering wheel shimmy.
OEM & Customization Services:We provide comprehensive private-labeling options for established automotive warehouse distributors. From custom-branded laser marking on the bearing outer face to tailored, moisture-barrier bulk master cartons, we build the product to reflect your brand's commitment to quality.
FAQ:
Q: Is this bearing designed for front axle or rear axle installation?A: While application-dependent, the DAC42800045 is predominantly spec'd for the heavily loaded front steering axles of premium crossovers and utility platforms.
Q: Why does this wheel bearing utilize a split inner ring?A: The split inner ring allows our assembly facility to insert a higher number of larger steel balls, vastly increasing the bearing’s overall load capacity compared to a solid-ring design.
Q: Is this unit compatible with ABS-equipped braking systems?A: This variant utilizes high-protection rubber-and-steel composite dust seals and should be paired with vehicles using axle-mounted external ABS wheel speed sensors.
