Bearing housing assembly

Description

Product Overview
Bearing housing assembly is a precision-engineered mechanical component that supports and secures rolling-element bearings within rotating equipment. It provides the structural interface between bearings and machinery frames—ensuring alignment, load distribution, sealing, and simplified maintenance for shafts and rotating assemblies. Designed for heavy-duty industrial service, this assembly maximizes equipment uptime by combining robust materials, tight tolerances, and integrated sealing and lubrication features. Strategically, reliable bearing housings reduce total cost of ownership by preventing premature bearing failure, lowering maintenance labor, and enabling predictable asset performance across mining, power generation, manufacturing, and material-handling operations.

Key Specifications & Technical Characteristics

• Material: High-strength ductile cast iron (EN-GJS-400-15) as standard; alternatives available: stainless steel (SS304/SS316), nodular cast iron, and alloy steel on request.

• Surface treatment: Shot-blasted and primed; options: epoxy powder coat, zinc plating, or phosphating for enhanced corrosion resistance.

• Dimensional standards: Manufactured to ISO 113/ABEC-graded mounting bore tolerances; custom bore sizes and bolt patterns available per drawing.

• Bearing fit: Precision machined housings for H7/N7 fits; optional pre-mounted bearing or reamed bore for press-fit assemblies.

• Sealing: Integrated labyrinth and single/double-lip seals with options for felt, rubber (NBR/VMQ), or spring-energized seals.

• Lubrication features: Grease fitting (Zerk) locations, purge/lubrication ports, and optional grease reservoirs or automatic lubrication adaptors.

• Load capability: Designed for radial and axial loads per application; specific dynamic/static load ratings depend on matched bearing.

• Physical characteristics: Typical unit weight range 3–250+ kg depending on size; standard finishes in black primer or customer-specified RAL color.

• Tolerances: Housing bores ±0.02 mm; bearing seat runout <0.03 mm (typical — confirmed on drawing).

• Packaging options: Export-grade wooden crates, palletized skids with corrosion inhibitor film, or bulk boxed for factory-fit assemblies.

• Shelf life: Not applicable as a mechanical assembly; recommended storage in dry, temperature-controlled warehouse to preserve seals and coatings.

Core Industrial Applications

• Mining and aggregates: Used in conveyors, crushers, and vibrating screens to withstand shock loads, abrasive environments, and heavy radial loads. Robust sealing and material choices extend bearing life under contamination.

• Power generation: Supports turbine auxiliaries, fans, and pump shafts where vibration damping and precise alignment ensure efficiency and safety.

• Pulp & paper and material processing: Enables continuous operation of rollers, calenders, and refiner shafts with reliable lubrication management to reduce downtime.

• Steel and metalworking: Employed in rolling mills, conveyors, and drive systems where thermal and mechanical stresses demand durable housing construction.

• Food & beverage and pharmaceuticals (sanitary variants): Stainless-steel housings with hygienic seals and smooth finishes for washdown and contamination-sensitive lines.
  Why it outperforms alternatives:

• Precision machining and optimized sealing reduce ingress of contaminants that cause premature bearing failure.

• Modular design allows rapid field replacement and lower mean time to repair (MTTR) versus integral housings.

• Material and coating options tailored to corrosive or high-impact environments deliver longer service life and lower lifecycle cost.

Competitive Advantages

• Quality consistency: ISO 9001-compliant manufacturing with batch traceability, dimensional inspection reports, and material certificates (MTC) supplied per shipment.

• Supply reliability: Scalable production lines with safety-stock policy and prioritized fulfillment for core sizes reduce lead times for repeat buyers.

• Logistics capability: Packaged and labeled for multimodal transport, export documentation (COO, packing list) and DDP/DDU shipping options available.

• Price competitiveness: Tiered pricing for annual contracts and volume discounts for strategic partners; cost engineering available for long-term programs.

• Sustainability: Material-efficiency designs reduce weight without sacrificing strength; options for low-VOC coatings and recyclable packaging on request.

• Technical support: Application engineering, CAD models, installation guides, maintenance schedules, and on-demand field-service support or training.

Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT

• Loading capacity (MT per container): Typical loading capacity 20–22 MT per 20’ container (depending on part geometry and packing method); 44–46 MT per 40’ high-cube container when palletized and secured.

• Lead time: Standard lead time quoted per size; expedited production available for core SKU contracts.

• Documentation: Supplied with inspection certificates, dimensional drawings, recommended lubrication schedule, and packing list.
