About Consolidated Bearings
Precision Rolling Bearings & Support Assemblies
Consolidated Bearings Company is a leading importer and wholesaler of high-quality Tier-1 bearings and related products, offering the industry's most comprehensive bearing portfolio with competitive pricing and exceptional availability. The company maintains deep inventory across all major bearing types and sizes, serving machine builders, maintenance facilities, and OEM assembly operations.
The Consolidated Bearings product range includes deep groove ball bearings for radial and low-thrust loads; self-aligning ball bearings for accommodating shaft misalignment; angular contact double-row ball bearings for precision spindle applications; tapered roller bearings for axial and radial load combinations; cylindrical roller bearings for high radial load capacity; needle bearings for compact design requirements; spherical roller bearings for heavy shock loads; and complete pillow-block assemblies with cast-iron or thermoplastic housings.
Consolidated operates the CBC (Consolidated Bearing Company) private-label manufacturing line, producing large volumes of common sizes—deep groove balls, spherical rollers, cylindrical rollers, needle bearings, and thrust bearings—with direct quality control and often at reduced cost compared to internationally-sourced OEM parts.
All bearings are rated per ISO 281 dynamic load rating standards and ISO 286 dimensional tolerance classes (P0, P6, P5). The company offers sealed, shielded, and open designs depending on environmental contamination and lubrication requirements. Bore sizes range from miniature (0.5 mm) through large industrial (over 200 mm).
ChatMRO connects maintenance teams, equipment builders, and spare-parts buyers instantly with the correct Consolidated bearing—specify bore diameter, load direction (radial/thrust/combined), speed category, and environmental exposure (dry/contamination-prone), and our AI surfaces matching bearing types and housings with availability and pricing from our indexed 30M+ component database.

Frequently asked questions
What's the difference between sealed and shielded bearings?
Sealed bearings have rubber or metal seals pressed into the bearing sides, preventing dirt and moisture ingress but also sealing in lubrication—they're maintenance-free but cannot be cleaned. Shielded bearings have metal or thin seal covers that reduce contamination while allowing grease escape—better for high-temperature or dirty environments. Sealed is preferred for clean, sealed environments; shielded for outdoor or harsh conditions.
How do I calculate the required bearing size for my application?
Calculate radial load (perpendicular to shaft) and thrust load (along shaft axis). Cross-reference bore diameter and combined load against ISO 281 dynamic load rating tables—the bearing must withstand the required load at your operating speed for your desired life (typically 10,000 to 25,000 hours for industrial duty). Consolidated technical support can assist with selection.
What's the difference between a pillow block and a flange bearing mount?
A pillow block is a cast-iron or polymer housing containing the bearing and designed to bolt directly to a shaft or foundation, ideal for pedestal mounting. A flange bearing mounts directly to a motor or shaft face with bolts. Pillow blocks are adjustable and easier to replace; flange mounts are compact and space-efficient. Choose based on mounting space and accessibility requirements.
How often should I regrease sealed bearings?
Most sealed bearings are pre-lubricated and require no maintenance—grease is sealed inside for the bearing's life. Re-lubrication is not recommended and can cause overgreasing, which increases drag and heat. If a sealed bearing fails, replacement is the only option; repair is not practical.
What bearing type handles radial loads, thrust loads, and misalignment simultaneously?
Spherical roller bearings are the best choice—they tolerate radial loads, combined radial/thrust loads, and shaft misalignment up to ±2 degrees simultaneously. Tapered roller bearings also handle combined loads but less misalignment tolerance. For maximum misalignment (±5+ degrees), self-aligning ball bearings are preferred, though they sacrifice thrust load capacity.
