Ultra Kleen

Polymer and stainless steel housed mounted bearings

Hydro Armor seal
Designed with four contact lip seals and an extended metal flinger for maximum protection, the Hydro Armor seal:
• Protects lubrication from contamination and washout
• Eliminates seal blowout due to mechanically retained design.

Grease washout is the most common failure in washdown applications. Dodge E-Z and Ultra Kleen bearings are designed with innovative features to keep lubrication in and contaminants out.

Maxlife cage
Patented two-piece design that creates a constant grease compartment around each of the rolling elements.
• Compartments provide constant contact between balls and grease to prevent wear and minimize friction.
• Holds in the grease to prevent it from being washed out during high pressure cleaning

Insert
The Ultra Kleen features inserts made of 100% stainless steel and includes set screws positioned at 65 degree angles to provide maximum locking force without compromising inner ring strength. The inserts each include a stainless anti-rotation pin to prevent insert rotation in the housing under load which may cause premature bearing failure. Stainless inserts eliminate the possibility of contamination due to chipping and flaking, commonly found in inserts which are coated with zinc or thin-dense chrome.

Sealing
Retaining lubrication and preventing contamination from entering the bearing is critical in harsh environments. That is why Dodge has developed the premium Hydro Armor sealing system for maximum sealing effectiveness under these conditions. The seal includes two patented features unique to Dodge bearings; these features are standard on the Ultra Kleen product. The first is a triple-lip seal designed to maximize sealing and produce less drag than other multi-lip seals. The Dodge patented triple-lip design uses a mechanically retained seal with two contact points on the inner ring and one contact point riding against the flinger surface. Three points of contact maximize the ability of the seal to guard against contamination and to retain lubricants. The Hydro Armor seal incorporates the industry’s first internal rubberized flinger. This flinger uses molded rubber to provide additional protection from contaminants entering the bearing. Located behind the stainless steel flinger, the design shields the rubber lip from accidental damage due to high pressure washdown required in the food processing industry. This superior design will allow effective cleaning and increase bearing service life, leading to extended up-time for our customers. When used in conjunction with one another, the triple-lip seal and internal rubberized flinger create a sealing system that is ideal for demanding environments.

Retainer
The Maxlife cage is the product of extensive research and development in retainer technology and industry leading engineering. The cage features a two-piece design that creates a grease compartment around each of the rolling elements. These compartments allow balls to be constantly in contact with grease, so a good oil film will always exist to prevent wear and minimize friction and heat. The Maxlife cage reduces the relative motion between bearing components and grease which results in lower operating temperatures and extended life. The compartmental construction of the cage tends to hold in the grease and prevent it from being washed out in extremely wet or dirty conditions. This feature allows the bearing to be re-lubricated with less frequency than standard designs require, while extending bearing life.

Lubrication
