The ZB6606 Stainless-Steel Pulley Block is a compact yet heavy-duty solution for redirecting or tensioning wire rope in marine, industrial and home applications.
CNC-milled from one-piece AISI 304 stainless steel, the side plates, axle and housing resist rust even after years of salt-water spray.
A low-friction nylon sheave (25 mm) spins on a sealed stainless bushing, giving you 92 % efficiency—higher than cast blocks twice the size.
| Feature | User Benefit |
|---|---|
| Full-SS304 Body | Zero rust, zero staining; passes 1 000 h salt-spray test. |
| Sealed Nylon Sheave | Quiet, self-lubricating, UV-stable; accepts 3–8 mm wire or 6–12 mm rope. |
| Smooth Flame-Polished Edges | Won’t chafe lines or snag sails. |


Q: Is the nylon wheel UV-proof?
A: Yes, PA6 is compounded with 2 % carbon-black UV inhibitor; 5-year outdoor lifespan typical.
Q: Can I use this pulley for continuous 24 h cycling?
A: For high-cycle applications (>500 cycles/day) we recommend our ZB6606-B version with ball-bearing; contact sales.
Q: Will 1×19 stainless wire rope wear the groove?
A: Groove hardness 75 Shore D; after 3 000 km of 4 mm 1×19 wire, groove depth wear <0.2 mm.
Q: Magnet test?
A: 304 stainless is nominally non-magnetic; slight pull on edges due to cold-work is normal and does not affect corrosion resistance.
