With its premium sealed design and precision tolerances, the First Shaft Front Bearing delivers unwavering stability, making it the first choice for fleet owners and independent workshops who demand zero compromises.
The First Shaft Front Bearing is not just a spare part—it is a performance upgrade. Manufactured with high-grade chrome steel and double-lip rubber seals, it effectively blocks contaminants while retaining lubrication. Whether you operate in dusty mines, wet construction sites, or long-haul highways, this bearing maintains its clearance and preload, drastically reducing unscheduled downtime.
2RS rubber seals resist mud, water, and debris
Optimized cage design for radial & axial forces
Operates from -30°C to +120°C without failure
Grease-packed for 50,000+ km maintenance-free
Every 6305-2RS bearing undergoes stringent dimensional inspection to meet ISO 15 and DIN 620 standards. The inner and outer rings are precision-ground to sub-micron tolerances, ensuring a perfect fit on the first shaft of Howo and Sitrak transmissions. The bearing’s radial internal clearance is set to C3 as standard, allowing for thermal expansion during high-speed operation.
