FAQ
The questions our customers actually ask — about compatibility between 3300 and 3500 hardware, spare storage, shipping, warranty, and how to get a part identified from a photo. Answers are kept short and practical, and new questions are added as they come in.

How do I choose between 8 mm and 5 mm proximity probes?
Follow the installed system, not preference: the tip diameter is fixed by the probe bore in the bearing housing and by the calibrated linear range your Proximitor was set up for. 8 mm is the standard for most sleeve-bearing machines; 5 mm appears where the mounting hole is smaller or where a smaller linear range…
-
Can you cross-reference my old part number to a current replacement?
Yes — that is a daily request here. Send the number exactly as it appears on the nameplate, including any suffix, and we return the direct replacement if one exists, or the closest substitute with the notes on wiring, termination, or configuration. Suffixes matter: length, connector type, and certification variants each change the part, so…
-
How can I get a quote or a retrofit plan?
Send us the list — model numbers, nameplate photos, or even a photo of the rack — through the contact form or WhatsApp. Within one business day you receive a line-by-line quote with availability and lead time. For retrofit planning, include the machine train and what you want to achieve (system renewal, obsolescence cover, or…
-
Do you provide datasheets, manuals, and technical documentation?
Yes. Every product page carries the key specifications, and the Tech Docs section collects our guides — overviews, selection guides, installation notes, and troubleshooting checklists. For original factory manuals we can supply the official documentation for most 3300/3500/7200 items on request, together with our own stamped service sheets. Ask with your inquiry and the documents…
-
Do you offer on-site commissioning and technical support?
TenBN is a parts supplier: our core service is identifying, stocking, and dispatching the correct spare quickly. For on-site commissioning we work with a network of rotating-machinery service partners and can put you in touch with a vetted provider in your region. What we do support directly — every day — is remote technical help:…
-
How fast can you ship, and do you deliver worldwide?
In-stock items dispatch within 24 hours on business days; the quoted lead time you see is the dispatch promise, and shipping from our forwarders runs from overnight (EU/US domestic) to 2–5 days for most international destinations. We ship DHL/FedEx/UPS with export documentation, and dangerous-goods-free electronics move without special handling. Delivery terms are flexible — EXW,…
-
What warranty do you provide on your products?
Factory-new items carry the full manufacturer warranty; tested surplus and service-stamped parts carry the TenBN functional warranty stated on your quote — typically 12 months on condition-based items. The warranty covers function against the original specification: if a part we supplied does not perform as specified, we replace it or refund, and we support the…
-
Are 3300 series and 3500 series modules interchangeable?
No — the two systems are electrically and mechanically different. A 3300 monitor does not fit a 3500 rack, and 3300 XL probes connect to 3300-style Proximitors, not directly to 3500 monitor inputs. Probes themselves can often be re-terminated to a newer system, but monitors, racks, and power supplies are not cross-compatible. Send us your…
-
Are your Bently Nevada products genuine and factory-new?
Yes. Every module we ship is either factory-new in original packaging or a tested surplus part that is explicitly labelled as such on the quote — never refurbished without disclosure, and never counterfeit. Surplus units are functionally tested, cleaned, and packed with ESD protection, and carry our own warranty on top of the description. If…
-
Do you stock spare parts for discontinued 3300/3500 series models?
Yes — discontinued does not mean unavailable. Large parts of our stock exist precisely because the installed base of 3300, 3300 XL, and 3500 hardware keeps running. We stock current-replacement modules, legacy sensors, and direct-fit spares for most rack positions, and where a direct part is unavailable we propose the closest substitute with the wiring…
