SKF SSV 8/4-KNSI Progressive Distributor
The SKF SSV is a fixed-volume progressive lubricant metering distributor family, also known under the Lincoln brand. This page covers part reference 619-36434-3, an electrically monitored variant used in centralized lubrication systems. Progressive distributors meter lubricant in a defined piston sequence, delivering a fixed quantity to each outlet in turn.
How Progressive Metering Works
Lubricant entering the distributor moves pistons in a defined sequence, and each piston movement meters a fixed quantity to an outlet. The outlets are hydraulically interdependent, so a blocked outlet or downstream line stops the distributor cycle. That stoppage can be detected by a monitoring device, which is the key reason to choose a monitored variant like the KNSI.
What 8/4 and KNSI Actually Mean
The number in SSV 8 denotes the nominal number of outlets, and official tables list models such as SSV 6, SSV 8, and SSV 10. The notation 8/4 is used by distributors to describe eight outlet positions arranged as four combined pairs, but it is not a standard SKF family designation. Confirm internal outlet bridging from the part drawing before counting usable points.
K and KN are real official SSV variants, and a Lincoln listing shows SSV 8-KNSI as an electrically monitored metering-device variant. That listing is associated with listing 619-29000-1 and a 20 to 265 VUC designation. The SI element relates to electrical switching or indication, not to a check valve.
Official Family Connections and Variants
- Inlet: G 1/8 or 1/8 NPTF
- Outlets: M10x1
- Family models: SSV 6, SSV 8, SSV 10
- Official variants: K and KN
- Stainless steel versions: distinct parts using VA 1.4305 and VA 1.4571
- 350 bar is a commonly published operating figure for the SSV family, but confirm the value for part 619-36434-3 from the part drawing or manual
What Older Listings Got Wrong
Older reseller listings described this part as an integrated check-valve assembly with a special connection standard, a wide temperature span, and a stated metering accuracy. The official SSV family data does not support those descriptions. Confirm configuration, pressure, and lubricant suitability from the drawing, manual, and quotation.
Monitoring and Ordering Practice
This is an aftermarket distributor, not manufactured, sponsored, or endorsed by SKF or Lincoln. The monitored variant pairs with cycle-based controllers such as the SM-AC control timer in d3 cycle mode. M10x1 outlet threads mate with standard adapters like the M10x1 adapter.
Ordering checklist: confirm the nameplate part number, outlet count and bridging, inlet form, monitor voltage, and any stainless requirement. Part 619-36434-3 could not be matched to the standard SSV listing tables in the retrieved official assembly documentation. Confirm the exact configuration, outlet bridging, and monitor voltage from the nameplate and quotation. Contact us for a quote.
Frequently Asked Questions
What is the SSV 8/4-KNSI?
The SSV 8/4-KNSI is an SKF fixed-volume progressive metering distributor with reference number 619-36434-3. It meters lubricant in a fixed sequence to multiple outlets.
What does progressive mean here?
Pistons meter lubricant in a defined sequence, and each outlet receives a fixed quantity. Outlets are hydraulically interdependent, so a blockage stops the cycle.
What does 8/4 mean?
It means eight outlet positions arranged as four combined pairs per distributor shorthand. Confirm internal outlet bridging from the part drawing before counting usable points.
What does KNSI mean?
KNSI appears in Lincoln listings as an electrically monitored metering-device variant. The SI element relates to electrical switching or indication, not a check valve.
What connections does the SSV family use?
The official family connections are inlet G 1/8 or 1/8 NPTF. Outlets are M10x1.
What pressure does it handle?
350 bar is a commonly published operating figure for the SSV family. Confirm the exact value for part 619-36434-3 from the part drawing or manual.
Do stainless versions exist?
Yes, stainless steel versions exist as distinct parts. They use materials VA 1.4305 and VA 1.4571.
What did older listings get wrong?
They described a check valve, a special connection, and an accuracy figure the official data does not support. Confirm configuration from the drawing, manual, and quotation.
Which oils or greases apply?
No universal oil viscosity range or grease grade is published for every SSV version. Confirm lubricant suitability from the SKF manual for the exact part.
