01. Reinforced Alternator-Series Profile

Featuring a widened 13mm cross-section, the 15x35x13mm footprint is deliberately engineered to handle severe radial stresses alongside moderate axial loads. The deeper, precision-ground track geometry absorbs high operational vibrations easily, preventing housing distortion and micro-misalignments.

02. Advanced Contact Sealing for Harsh Conditions

The B15-69-2RS relies on dual molded synthetic rubber seals (2RS) that make uniform physical contact with the inner ring. This airtight protection shuts out mud, road grime, water splash, and fine metallic dust, maintaining clean internal mechanics and preventing premature bearing burnout.

03. High-Purity GCr15 Chrome Steel Composition

Forged from premium-grade, vacuum-degassed GCr15 chrome steel, the bearing rings and ball sets undergo specialized thermal hardening to ensure high Rockwell hardness. This advanced metallurgy translates to exceptional fatigue resistance, lower structural wear, and ultra-quiet execution under full load.

Design & Configuration

The standard B15-69-2RS comes factory-filled with high-temperature, anti-wear grease tailored specifically to handle the intense thermal conditions of automotive engine compartments. For specialized application requirements, we can provide this variant with C3 internal clearance to effectively manage intense shaft expansion, or craft components in high-grade stainless steel for highly corrosive environments. If your system requires minimal starting torque and operates in a pristine environment, ask about our non-contact metal shielded B15-69-ZZ models.

"The B15-69-2RS combines a ruggedized structural footprint with an absolute barrier against contaminants, driving maximum operational reliability for modern automotive and industrial motors."
