"No-Leak" Seal From Falk Keeps Oil In And Dirt Out

The Falk Corporation, Milwaukee, Wise., has developed the Magnum ™ Seal. An innovative seal with no wearing parts, it is said to offer long life protection for parallel shaft and horizontal right angle speed reducers.

When properly installed and maintained the seal will not leak.

The Magnum Seal solves the leakage problems encountered with conventional single-lipped and double- lipped contact seals and helps protect against damage to shafts.

Because it has no wearing parts it is said to last as long as the drive.

The inner cage of the seal, designed to radial and axial design clearances of approximately .005- inches, fits precisely over the drive shaft and against the bearing. Although the shaft rotates without touching the seal, there is virtually no passage of oil under normal operating conditions.

It also features the oil drainback which assures oil tightness of the seal. The little oil which might get through is immediately routed back to the gear box via this drainback passage in the inner seal cage and housing wall.

The Magnum design traps dirt, grit and abrasive particles in the grease in the outer cover before they reach the oil sealing surface. As further protection against contaminants, a fitting on the cover and a grease-exclusion seal permits purging the chamber with fresh grease.

The Falk Corporation is a subsidiary of Sundstrand Corporation.
