Overview
Quarter-turn locking for secure shaft attachment
Dodge® Eccentric Collar mounted ball bearings use an eccentric locking collar that secures the bearing inner ring to the shaft. The locking collar bearings fit applications that need simple shaft attachment, shock-load capability, and options for contamination protection.
The product line spans light-, normal-, and intermediate-duty series, plus Harsh Duty™ configurations, across pillow block, flange, take-up, and hanger housing styles. Its range lets you match duty level, sealing, and lubrication to each piece of equipment while keeping one familiar eccentric collar locking method across the line.
Key features and benefits
Quarter-turn eccentric collar with one set screw
A quarter-turn in the direction of shaft rotation locks the inner ring, and one set screw holds the collar for quick, simple installation.
Case-carburized inner ring
The case-carburized inner ring supports durability and high shock-load capability in demanding equipment.
Controlled fit for ±2 degrees static misalignment
The tightly controlled fit between the bearing insert and housing allows ±2 degrees of static misalignment to accommodate minor mounting errors during installation.
DualGuard™ single-lip seal with rubberized flinger
DualGuard single-lip seals with a rubberized flinger help keep contaminants out and clean grease in, extending service life.
33 percent fiberglass-reinforced nylon cage
Heat-stabilized nylon with fiberglass reinforcement flexes under misalignment for longer life and resists fatigue better than metallic cages.
Pillow block, flange, take-up, and hanger housings
Pillow blocks, 2-, 3-, and 4-bolt flanges, tapped bases, piloted flanges, take-up units, cylindrical units, and hangers help match these bearings to equipment requirements.
