240 Seal Guard Roller Chain

#240 seal guard roller chain is a maintenance free high performance roller chain. The maintenance free class of roller chains means that this chain does not require continual lubrication such as other chains do, 240 seal guard chain is also factory pre-loaded and pre-stretched to eliminate almost all stretch in the chain. This chain also runs on standard 240 sprockets, making it easy to make the switch! When comparing a Seal Guard roller chain versus the O-Ring roller chain there are significant gains in performance, durability, and strength.

240 Seal Guard Chain 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 wear.
• Solid Bushings and Solid Rollers for uncompromising durability and performance throughout the chain life.
• Precision heat treated components (pins, bushings, rollers, side plates).
• Wide waste side plates for improved durability, shock resistance, and fatigue performance.
• Factory pre-stretched for reduced chain stretch over-time and minimum initial chain stretch.
• Stainless Steel Blast Coated for slight anti-corrosion
