Welcome to Linqing Xinshengdi Bearing Co., Ltd.
DAC25520037 Wheel Hub Bearing (25x52x37mm)
- Envelope Dimensions: Precise 25mm bore, 52mm outer diameter, and 37mm width matching strict OE configuration layouts.
- Angular Contact Geometry: Optimally balanced ball-complements and contact angles to handle intersecting radial and axial tracking forces.
- Elastomeric Sealing: Dual-lip rubber seals designed to tightly hug the inner ring shoulder, locking out high-velocity road splash and road dust.
Measuring 25 mm x 52 mm x 37 mm, the DAC25520037 wheel hub bearing provides robust support for compact automotive applications. Engineered to endure continuous dynamic loads, this bearing is manufactured using premium-grade bearing steel. Our modern DBS manufacturing plant employs automated grease filling and advanced sealing technology, ensuring the DAC25520037 offers maximum resistance to moisture, road debris, and high-temperature environments.
Product Overview:The DAC25520037 is a Generation 1 double-row angular contact ball bearing designed for the front or rear wheel spindles of compact passenger vehicles and light urban hatchbacks. These vehicles require a highly compact wheel geometry that balances low rolling resistance with reliable structural rigidity. The unified outer ring housing two separate rows of steel balls provides exceptional resistance to cornering moments, ensuring stable vehicle handling through tight urban radiuses and unpredictable city streets.
Friction mitigation is critical for improving vehicle fuel economy and extending battery range in modern electric city cars. Within our assembly production line, the internal raceways of the DAC25520037 are super-finished to a mirror shine, reducing mechanical drag to the absolute minimum. Our 100% Individual Quality Verification checks the factory-set internal axial clearance after seal pressing, guaranteeing that every single unit delivered functions with zero play and zero premature heat buildup.
OEM & Customization Services:We provide Comprehensive OEM Kitting & Packaging for high-volume automotive spare parts distributors. The DAC25520037 can be packaged as a complete axle repair kit containing the corresponding hub nuts, circlips, and split pins specified for rapid workshop installations.
FAQ:
Q: What type of internal grease is utilized in this specific model?A: We pre-fill the assembly with a high-performance, shear-stable polyurea grease that resists water wash-out and maintains structural consistency under heavy city braking.
Q: Does this model feature a magnetic ABS encoder ring?A: The DAC25520037 relies on standard dual-rubber seals and is engineered for vehicles using traditional mechanical tone wheels located on the CV axle shaft.
Q: What is the primary cause of premature failure in Gen 1 wheel bearings?A: Improper press-fitting during workshop installation is the leading cause. Mechanics must always apply pressure to the outer ring when pressing into a steering knuckle to avoid brinelling the raceways.
