FLOWSERVE High Precision Machined Stainless Steel Bearing Spare Parts for Water

When a maintenance team needs more than just one bearing — when they need the matching housing, the seal, the shaft sleeve, and the coupling all lined up for the same overhaul — that is where our product range fits in. We supply across multiple categories: centrifugal pump spare parts, variable-frequency drives, servo motion controllers, touch-screen operator panels, motor starter cabinets, electric motors, mechanical seal cartridges, flexible shaft couplings, and gear reduction units. For customers with sites abroad, we can deploy personnel to perform 3D laser field scanning of worn pump components and supervise re-installation and start-up. This eliminates the back-and-forth of coordinating a measuring team, a foundry, a machine shop, and a field service crew through separate contracts.

Getting the right bearing for a FLOWSERVE pump involves more than matching the number on the old bearing's side face — although that is the quickest route. The ordering sequence below covers the steps we follow to avoid the wrong fit or incorrect clearance class.

1. Submit Inquiry — The fastest method: forward the bearing designation stamped on the worn component (e.g. 6310 C3). If the marking is illegible, send pump model plus bearing location (drive end or non-drive end), and a photo of the bearing in its housing showing approximate dimensions
2. Cross-Reference Check — We compare the supplied bearing code against our interchange database and confirm bore (d), outside diameter (D), width (B), and type — deep groove ball, angular contact, cylindrical roller, or tapered roller
3. Grade & Clearance Confirmation — Verify precision level (P0 standard, P6 for higher accuracy, P5 for precision spindles), radial clearance class (C3 for normal pump service, C4 for high temperature, CN for low temperature), cage material (steel stamping, machined brass, or polyamide), and lubrication (open, shielded, or sealed; grease type if pre-packed)
4. Quotation Issued — Documented quote listing bearing designation, quantity breaks, delivery window, packing method, and incoterms
5. Dispatch & Documentation — Payment received → stock pick confirmed → individual bearing boxes packed into export carton → inspection certificate and packing list attached

Each bearing we supply is checked against published dimensional and running-quality standards before release:

• Dimensional Verification — Inner bore (d), outer diameter (D), and assembled width (B) measured to ISO 492 tolerance grades; results compared against the specified class
• Clearance Measurement — Radial internal clearance for ball and cylindrical roller bearings; axial clearance for tapered roller bearings — verified against C3, C4, or CN target range
• Noise & Vibration Test — Audible running quality checked on a test spindle; vibration acceleration measured against grade limits; any abnormal noise or elevated vibration flagged for rejection
• Raceway & Rolling Element Visual — Inspected under magnification for flaking, indentations, rust staining, heat discoloration, and cage deformation
• Grease Fill Verification — Sealed and shielded bearings checked for correct grease charge quantity and base oil type if specified on the order
• Traceability Marking — Part number, manufacturing lot code, and date code stamped or laser-marked on each bearing for full lot traceability

Certifications: ISO9001:2015, ISO14001:2004, API Specification Q1.

The handling a bearing receives between the warehouse and the installation point has a direct effect on its service life. A bearing that arrives with brinelled raceways from rough handling, or with moisture corrosion from inadequate sealing, will fail prematurely regardless of its quality grade. Our packing routine is designed to avoid those outcomes:

• Individual Boxes — Each bearing sits in its own manufacturer-issue cardboard box with a silica gel desiccant pack inside
• Anti-Rust Protection — Standard bearings receive a vapor-phase corrosion inhibitor (VCI) wrap; stainless steel variants are vacuum-sealed in PE/aluminum laminate pouches for extended shelf life in humid coastal environments
• Export Carton — Individual boxes consolidated into a double-wall corrugated master carton, labelled "Precision Components — Handle with Care" on all sides
• Wooden Crate — Orders exceeding 20 pieces or those destined for sea freight consolidation are packed in ISPM 15 heat-treated plywood crates with internal foam partitions
• Custom Labelling — Customer-specified part numbering, barcode labels, and packing slip formats are supported on request
