Life - An estimate which is too low leads to early failure, an estimate which is too high makes the Constant Force spring larger and more expensive than necessary.

Force - should equal the requirement of the application, normal tolerance is +/- 10%.

Life - An estimate which is too low leads to early failure, an estimate which is too high makes the spring larger and more expensive than necessary.

Torque - should equal the torque required to drive the mechanism plus the governor in the application, normal tolerance is +/- 10%.

W: Maximum available width space (mm) L: Maximum available length space H: Maximum available height space (mm)

Force The force of the spring should be equal to the spring force required to obtain the desired brush pressure. Normal tolerance is +/- 10%.
