#120 we offer 1-stop solution for the purchase of mechanical power transmission and pto shaft, agricultural gearboxes products in China. Manufacturer & distributor of roller & wire rope end chain & sprockets. Types of chain & sprockets include alloy, high10sile transport, high chain & sprocket test & proof coil chain & sprockets. Applications include log chain & sprockets, cargo lashings, pipe line handing, tailgates, guard rails & switch chain & sprockets.seal guard roller chain & sprocket is a maintenance free high performance roller chain & sprocket. The maintenance free class of roller chain & sprockets means that this chain & sprocket does not require continual lubrication such as other chain & sprockets do, 120 seal guard chain & sprocket is also factory pre-loaded and pre-stretched to eliminate almost all stretch in the chain & sprocket. This chain & sprocket also runs on standard 120 sprockets, making it easy to make the switch! When comparing a Seal Guard roller chain & sprocket versus the O-Ring roller chain & sprocket there are significant gains in performance, durability, and strength.
120 Seal Guard Chain & Sprocket Difference
- Unique anti corrosive stainless steel spring type contact seals fitted between link plates prevent penetration of abrasive materials while sealing in high quality bearing grade lubricant, thus minimizing elongation due to chain & sprocket wear.
- Solid Bushings and Solid Rollers for uncompromising durability and performance throughout the chain & sprocket life.
- Precision heat treated comp1nts (pins, bushings, rollers, side plates).
- Wide waste side plates for improved durability, shock resistance, and fatigue performance.
- Factory pre-stretched for reduced chain & sprocket stretch over-time and minimum initial chain & sprocket stretch.
- Stainless Steel Blast Coated for slight anti-corrosion
