Better Chain Performance

What are some guidelines for better chain performance?

  • FREQUENT LUBRICATION. Bare metal-to-metal contact leads to wear and metal fatigue; therefore, good lubrication is essential to chain performance and life. Manual lubrication (brush or spout can every 8 hours) provides the lowest performance. An oil bath increases the speed limit by 7 to 10 times.

FEET PER MINUTE

Lube Type / Chain No: #40 #50 #60 #80 #100 #120 #140 #160
Type A (manual): 300 250 220 170 150 130 115 100
Type B (oil bath): 2300 2000 1800 1500 1300 1200 1100 1000
  • THE RIGHT OIL. Oil has to get between the moving parts of the chain to be effective. Smaller chain needs lighter oil; however, increasing temperatures require heavier oil. See the accompanying table.
