Womala Tapered Roller Bearing OE 1409810305 for Mercedes Benz Wheel Bearing System Parts
The Tapered Roller Bearing (OE: 1409810305) is a critical load-bearing component for specific Mercedes Benz models (211616 E 270 CDI, 220073 S 55 AMG). Typically installed in the vehicle’s drivetrain or chassis (e.g., axle, differential), it supports radial and axial loads simultaneously while enabling smooth rotational movement. As an OE-grade part, it meets Mercedes Benz’s strict standards for wear resistance, load capacity, and dimensional precision, ensuring seamless compatibility with the vehicle’s mechanical system and reliable operation across driving conditions (e.g., city roads, highways, heavy-load scenarios).
Constructed from high-performance materials: the bearing features high-carbon chromium steel rings and rollers (for high strength and wear resistance) with precision grinding to ensure tight fit and minimal friction, extending service life and maintaining stable performance.
Core Functions
- Dual Load Support: The primary function is to bear both radial (perpendicular to the axis) and axial (parallel to the axis) loads, adapting to the complex force conditions of the drivetrain or chassis.
- Smooth Rotation: Reduces friction between rotating components, ensuring smooth movement of parts like axles or differential gears and minimizing energy loss.
- Durability Assurance: Resists wear and deformation under long-term load and high-speed operation, preventing mechanical failure and extending the lifespan of associated components.
Compatible Vehicles
This Tapered Roller Bearing is tailored for the following Mercedes Benz models and its respective OE number:
| Item | Details |
| Product OE Number | 1409810305 |
| Mercedes Benz Model | 211616 E 270 CDI 220073 S 55 AMG |
Notes: This Tapered Roller Bearing is model-specific and designed exclusively for Mercedes Benz 211616 E 270 CDI and 220073 S 55 AMG. Do not use it for other models or variants to avoid fitment issues such as improper load bearing, increased friction, or mechanical jamming. During installation, ensure the bearing is mounted with the correct preload (per manufacturer specifications) and that the mating components (e.g., shafts, housings) are clean and undamaged to guarantee optimal performance. Periodically check the bearing for signs of failure like abnormal noise (e.g., grinding, humming), excessive heat, or oil leakage, and replace it immediately if faults are found to prevent severe damage to the drivetrain or chassis.

Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
