The 7309 BECBP Angular Contact Ball Bearing features inner and outer ring raceways displaced along the bearing axis, which enables it to carry radial loads plus axial loads (thrust) in one direction. This bearing is commonly selected when you need higher speed capability and precise guidance compared with many thrust-bearing alternatives.
Use the following specs for purchasing, cross-checking drawings, and OEM matching to your equipment BOM.

A 40° contact angle helps the 7309 BECBP support higher axial loads (in one direction) compared with smaller contact-angle designs, making it suitable for demanding combined-load positions. Single-row angular contact bearings are often used in matched arrangements (DB/DF/DT) when customers need axial load capacity in both directions and improved system stiffness.
Because a single-row angular contact bearing takes axial load in one direction, buyers typically specify a paired or set arrangement to match the machine’s thrust directions. Common options include Back-to-Back (DB) for higher rigidity, Face-to-Face (DF) for better misalignment tolerance, and Tandem (DT) to increase axial load capacity in one direction—tell us your load direction and shaft/bearing seat details so we can recommend the correct arrangement.
Typical buyer industries include Building Material Shops, Manufacturing Plants, Machinery Repair Shops, Food & Beverage Factory operations, Retail, Construction works, and Energy & Mining. If you share your application (speed, load, temperature, lubrication method, and contamination level), we can confirm the best precision grade and fit suggestion for procurement.
We support OEM services such as customer logo/marking, customized packaging, and sample orders for approval before mass purchasing. Many B2B buyers evaluate suppliers across common sourcing channels before onboarding a vendor, so having clear OEM specs (marking format, carton layout, label/barcode, and inspection requirements) can speed up your internal approval process.
Price is negotiable based on quantity, precision grade (P0–P2), packaging requirements, and delivery terms. Send your required quantity, destination port/zip code, and target brand/reference number (if any), and we will reply with a quotation and lead-time.
Q1: Is 7309 BECBP suitable for axial load in both directions?
A: A single-row angular contact bearing carries axial load primarily in one direction; for axial loads in both directions, buyers usually use a DB/DF paired arrangement or choose a double-row angular contact bearing depending on stiffness and space.
Q2: Which precision grade should I choose (P0/P6/P5/P4/P2)?
A: For general industrial use, P0/P6 is common; for higher speed, lower runout, or spindle-like requirements, purchasers often specify P5/P4/P2—share your speed and accuracy needs and we’ll recommend a cost-effective grade.
Q3: Can you do OEM logo/marking on the bearing?
A: Yes, OEM/private label (customer logo) is acceptable; provide your marking artwork or required text format and we will confirm feasibility for sampling and mass production.
Q4: Do you offer samples before bulk orders?
A: Yes, sample offer is available so you can verify fit, noise/vibration, and installation before placing a wholesale order.
Q5: What packaging options are available?
A: Packaging can be made as customer required (individual box, industrial packing, barcode label, master carton, pallets); send your packaging spec and we’ll quote accordingly.
Q6: What information should I send to get a fast quote?
A: Bearing designation (7309 BECBP), precision grade, quantity, packaging requirement, target delivery time, and shipping destination—then we can respond with price and lead-time quickly.
If you want, paste your target market (EU/US/SEA), expected annual volume, and whether you need DB/DF/DT matching, and I’ll tailor the page copy more tightly to your highest-converting keywords and buying scenarios.
