ALPINE BEARING COMPANY, LLC

Alpine Bearing Company, LLC specializes in the precision manufacturing of ball and roller bearings, with a demonstrated focus on annular ball bearings for defense applications. Their core capability centers on high-tolerance bearing production, utilizing advanced metallurgy, precision grinding, and strict adherence to military-grade dimensional and performance specifications. The company delivers mission-critical components that ensure rotational integrity under extreme loads, vibration, and thermal stress—key requirements in aerospace, armored vehicle, and naval propulsion systems. Their technical expertise includes bearing geometry optimization, surface finish control, and material selection compliant with MIL-SPEC and ASTM standards, positioning them as a niche supplier of reliability-critical rotating system components. The contractor has established a direct relationship with the Department of Defense, supplying specialized bearing assemblies for defense platforms requiring durable, low-friction motion control. Their work supports systems where bearing failure could compromise operational readiness, indicating a trusted role in sustaining legacy and next-generation military hardware. Alpine Bearing Company operates within NAICS 332991, which encompasses the manufacturing of ball and roller bearings not classified elsewhere. This places them squarely in the defense industrial base as a Tier 2 supplier of motion control components, serving high-reliability sectors where precision engineering and consistent quality are non-negotiable. Their market positioning is that of a specialized manufacturer, not a broad-line distributor, emphasizing in-house production over sourcing or assembly. As a small business structured as a 2K entity, Alpine Bearing Company maintains a compact, focused operational footprint in Allston, Massachusetts. While they hold no formal government certifications, their ability to secure a DoD award demonstrates compliance with federal procurement standards and supply chain integrity requirements. Their geographic presence supports regional defense logistics networks, reinforcing their role as a localized but mission-critical supplier within the national defense industrial ecosystem.
