Bearing Housings FAQ
What bearing housings can you manufacture?
We manufacture pillow block housings, flange mount housings, take-up unit housings, cartridge housings, split housings, and custom bearing housings. All mounting styles and bearing bore sizes available.
What materials are best for heavy-duty bearing housings?
Cast iron provides excellent rigidity and vibration damping for heavy-duty applications. Aluminium 6061-T6 is used for lightweight applications. Steel 4140 is used where corrosion resistance or higher strength is needed. Stainless steel 316 is used in marine or wet environments.
What tolerances can you hold on bearing bores?
Bearing bores are machined to ISO286 bearing housing tolerances (typically H7, H8, or H9). Standard tolerance: ±0.05mm. Precision boring: ±0.02mm. Bore concentricity and roundness are maintained within tight limits for optimal bearing fit.
What is the typical lead time for bearing housings?
Simple housings: 2–3 weeks. Medium complexity: 3–4 weeks. Complex multi-bore assemblies: 4–6 weeks. Lead times depend on material, bore configuration, and surface treatment requirements.
Can you manufacture housings for custom bearing sizes?
Yes. We manufacture housings for any bearing size or type — ball bearings, roller bearings, tapered roller bearings, thrust bearings, or custom bearing geometries. CAD design and engineering support available.
Do you offer surface treatments for corrosion resistance?
Yes. Surface treatments include powder coating, paint, passivation (for stainless), and hard anodising (for aluminium). These protect bearing housings from corrosion in harsh environments.
