What are Bowman Oilless Washers?

Bowman Oilless washers are made from rotational cast high-strength bronze and use specially formed graphite plugs as the lubricant. They are designed for high-load, low-speed applications.

How do graphite lubricated washers work?

The specially formed graphite plugs provide lubrication within the washer, making Bowman Oilless washers suitable for high-load, low-speed applications.

What axial loads do these handles?

The axial load capacity depends on the washer size, operating conditions, and application. Contact Bowman to discuss your requirements and determine a suitable solution.
