Kluber Lubrication Kluber­alfa YV 93-1202 PFPE Grease — 1 kg (2.2 lb)

Kluber · Kluberalfa YV 93-1202 · High-Vacuum PFPE Grease · In stock

Kluber Kluberalfa YV 93-1202 is a fully-synthetic, high-purity perfluoropolyether (PFPE) grease thickened with PTFE, manufactured by Kluber Lubrication in Germany. It is engineered for bearings, linear guides, valves and gear couplings running in high-vacuum, oxygen-rich, plasma and reactive-gas environments where hydrocarbon or silicone lubricants would outgas, carbonise or react. KOEED stocks the 1 kg (2.2 lb) cartridge for OEM build-out and after-sales replenishment on Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE equipment lines.

Key Technical Specifications & Overview

The YV 93-1202 is built on a PFPE base oil that is chemically inert to most aggressive media — oxygen, chlorine, hydrogen chloride, ammonia, halogens and plasma — making it the default lubricant for the load locks, transfer chambers and robotic axes of semiconductor fabs. It is NSF H1 registered for incidental food contact, so it is also specified on pharmaceutical and food packaging lines driven by Allen-Bradley CompactLogix and Siemens SIMATIC cells.

Application Scenarios & Where It Fits

Kluberalfa YV 93-1202 is specified wherever hydrocarbon oils would fail — either because they outgas into the process, react with the gas chemistry, or carbonise at the bearing running temperature. The most common duty points we see quoted through BOM requests at KOEED are:

• Semiconductor front-end equipment — wafer-handling robot axes (driven by Yaskawa and Mitsubishi servo motors), load-lock and transfer-chamber bearings, ion-implanter rotation feeds, plasma-etch chamber door seals, ALD/CVD chamber rotation stages.
• Vacuum & pump systems — turbomolecular and cryopump bearing pre-lube, scroll-pump tip-seal lubrication, rotary-vane pump bearing reservoirs on Allen-Bradley-controlled roughing lines.
• Oxygen & reactive-gas service — O&sub2;, N&sub2;, Cl&sub2;, NH&sub3;, HCl, HBr and plasma-compatible valve stems, regulators and fittings. BOG (boil-off gas) compressor bearings on LNG and specialty-gas cabinets.
• Pharmaceutical & food processing — conveyor bearings, filling-machine slides, blister-pack tooling, steriliser-internal gear drives, all driven by Siemens SIMATIC and Omron SYSMAC control cabinets where the line runs open or in Class 100 / ISO 5 clean zones.
• Paint & coating lines — oven conveyor bearings, powder-coat cure-oven chains, e-coat tank agitator gearboxes running at 180–220 °C.
• CNC machine tools & robotics — spindle bearings and tool-changer cam followers on Fanuc-controlled machining centres, linear-guide blocks on Panasonic welding cells, vision-guided pick-and-place axes running KEYENCE inspection.
• Cleanroom-compatible drives — servo-amplifier cabinets, fan-cooled drives, harmonic-drive gearheads from Schneider Lexium families.

Integration Notes — Compatibility with Elastomers, Paints & Metals

Although the YV 93-1202 is not an electrical module, the integration "wiring" question for a grease is whether it is chemically compatible with the seals, paints, plastics and metals it will sit next to for the next 3–5 years of service. In our experience shipping into Allen-Bradley, Siemens and Mitsubishi servo cabinets, this is the most overlooked failure mode.

Installation & Commissioning Tips

The YV 93-1202 is a finished lubricant, not a kit, but the way it is loaded on a Siemens SINUMERIK spindle or a Fanuc robot axis is the difference between a 24-month re-grease interval and an unplanned weekend call-out. These are the steps our integration team follows on every cell we ship through our China sourcing arm:

1. Verify cleanroom discipline. Open the 1 kg cartridge only inside the clean zone where it will be used. Wipe the cartridge tip with PFPE-compatible isopropyl alcohol and load a fresh, lint-free nitrile or PTFE gasket on the dispense gun.
2. Purge the old grease. Pump the old lubricant out completely. PFPE / hydrocarbon cross-mixing destroys vacuum and oxygen performance. We provide purge-and-pack-out guidance for Allen-Bradley Kinetix drives and Mitsubishi MR-J4 servo gearboxes on request.
3. Apply the right volume. Fill the bearing housing to roughly 30–50 % of free volume. Over-packing causes the YV 93-1202 to churn and heat up; under-packing starves the contact zone at high RPM.
4. Run-in at low speed. Jog the axis for 5–10 minutes at 10–20 % rated RPM, then step up to 50 % and 100 % in two more intervals. Listen for any tone change — any rise in decibel reading beyond 3 dB indicates a seal or alignment problem, not a grease problem.
5. Commissioning log. Record date, ambient, axis, grease lot number and run-in time in the commissioning log; KOEED can ship with a batch-coded COA on request to support your quality system.
6. Storage of the opened cartridge. Re-cap immediately, store at +5 to +30 °C, and use within 12 months. PFPE does not oxidise, but particulate ingress in a half-used cartridge is the most common cause of premature bearing wear we see from KEYENCE vision cells and Schneider PacDrive axes.

Procurement, Warranty & Lead Time

Kluberalfa YV 93-1202 is held in our bonded Shenzhen warehouse in the original Kluber factory pack. Most orders placed before 14:00 CST on a business day ship the same day; air-freight to most major industrial hubs (SEA, LAX, FRA, DXB, ICN) clears in 3–5 business days. Lead time for back-order positions is 4–6 weeks ex-Munich, Germany. Every cartridge is shipped sealed with a verifiable lot number and a manufacturer COA on request.

Pricing is RFQ-driven — send a one-line email with part number, quantity and destination country and we will come back inside 24 hours on a business day with availability, unit price and freight options. The KOEED quotation includes batch-traceable documentation, 12-month storage warranty from the date of shipment (unopened original pack) and worldwide shipping through DHL / FedEx / UPS with full commercial invoice and HS code. For multi-line BOMs that pair YV 93-1202 with servo amplifiers, encoders or HMI panels from Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic or KEYENCE, use the Create a Quote form to upload the spreadsheet and we will quote the lot in one go.
