NSL self-lube
Food-safe · lube-free
NSF H1 food-approved oil-impregnated bush, so it runs without added lubrication. FG to 145°C, FGH to 220°C.
Beyond standard chain
Specialist chain for demanding applications
When commodity chain won't last, the engineered MAXTOP ranges will: sawmill, side-bow, self-lube, high-strength stainless steel and more — Merley Chains is the sole UK distributor.
The UK gap we're here to close
Most UK suppliers stock the commodity range and stop there. The specialist chain, engineered for heat, corrosion, curves, quiet running or brutal duty, is where machines fail — and it is where we put our focus. As sole UK distributor for MAXTOP, we bring those engineered ranges to British industry, from stock and with the technical support to match them to the job.
Specialist ranges
Engineered for the job standard chain can't do
Engineered specialist chain families, matched with the right sprockets and, where needed, adapted in-house.
MEGA II stainless steel
High-strength stainless steel
Flanged inner plates and double outer plates resist breakage under high loading — standard inner width, so it runs on standard sprockets.
Side-bow chain
Curved conveying
Flexes sideways to follow curved and inclined paths. Curve radii from 254 mm; extended-pin versions carry plastic flights.
High-strength (HV)
Heavy-load drives
Through-hardened pins for demanding drives. 60HV to 200HV, tensile up to ~51,000 kgf.
Hollow-pin chain
Attachment-ready
Hollow pins for fitting attachments, slats and extended pins, the basis of many conveyor builds.
Low-noise chain
Quieter running
Engineered to run quieter, to ~200 m/min, where noise is a working consideration.
Double Flex (DF)
Two-plane conveying
Articulates in two planes for timber and heavy conveying. Tensile to ~18,400 kgf. More ›
Sharp Top chain
Timber & board grip
Tooth-profiled plates grip timber and board. 80, 100 and 32B series, simplex to quad strand.
Welded Steel (WR/WH)
Rough bulk conveying
Welded, heat-treated mill chain for scraper and drag conveyors. Ultimate strength to ~92,700 kgf.
Drop-forged rivetless (X)
Overhead conveyors
X348–X678 rivetless chain assembles by hand, with trolleys, pushers and dog chain to suit.
Composite & poly-steel
Wet · hygienic · non-marking
Engineered-plastic, poly-steel and non-marking chains for wet, clean or delicate-product lines.
