I’m building a custom gearbox with 7075 T-6 spur gears, and I’m concerned
that aluminum flakes will enter the races on the roller bearings (SKF 2307) and cause premature failure. So my question is — should I place an oil seal on the shaft first to protect the bearing — or is this an unfounded concern and I should mount the seal in the typical manner outside the bearing? Or both? Or go with a sealed bearing? I’m confused and could use your expertise, please.

Sometimes I feel like I blink and another year is gone. By the time most of you read this, it will be at or near the end of 2015. If you’re like us, you’ll be reflecting on the past year and looking forward to the next.
One of the great benefits of Gear Expo for us here at Gear Technology is the opportunity to meet faceto-face with many of the people who, in one way
or another, contribute to our success throughout the year. After all, our success is dependent almost entirely
on information and the people who provide it. These contributors
include researchers at top technical universities, the heads of technology at major gear industry corporations, independent consultants with decades of gear industry experience, members
and volunteers at leading industry organizations like the AGMA,
our technical editors and others.
Reducing losses and increasing profits by instituting a motor management plan is what this series of articles is all about. Here in Part I, we discuss how to create a motor inventory and establish repair-or-replace motor guidelines. Subsequent topics in this
three-part series will address (Part II)
motor failure policies and purchasing
specifications, and (Part III) repair
specifications and preventive and predictive maintenance, respectively.
