Performance Mounted Ball Bearings

Bearings

Wide Outer Ring

Sealmaster has the industry’s widest outer ring. The black oxided outer ring

is 20 to 30% wider than industry standard outer rings. This feature results in

increased grease capacity, and room for improved sealing options. A wider

outer ring has increased surface area contact with the housing to better absorb

shock load.

Lock Pin and Dimple

The Sealmaster exclusive locking pin and dimple system provides a direct

lubricant path into the bearing cavity & ball path instead of around a lubrication

groove. The pin also prevents outer ring rotation (sometimes referred to as

“creep”), and allows ±2° static misalignment of the bearing insert.

Multiple Locking Methods

Setscrew Locking

120° spaced, balanced three point contact minimizes inner ring distortion

vibration, reduces noise, and improves reliability. Precision manufactured

diamond faceted setscrews contribute to improved clamping and resistance to

back out.

Features and Benefits

Skwezloc

Concentric Locking Collar

SKWEZLOC is a concentric locking collar clamp design that results in near-

perfect concentricity of the shaft to bearing bore and maintains near perfect

ball path roundness, while reducing fretting corrosion. This design eliminates

the shaft damage of setscrew locking, and minimizes bearing induced vibration

for smoother quieter operation. The collar has a TORX head cap screw that

outlasts stripping 12 times longer than hex head cap screws.

Multiple Sealing Options

Felt Seal with Flinger

The standard felt seal provides a tight labyrinth seal which retains lubrication

and acts as a lter to exclude contamination. The external stamping is a inger

which shields the felt from large contaminants and directs them away from the

sealing surface. The design operates with less drag and less heat generation

than rubber contact seals.

Single Lip Contact Seal

Single Lip Contact Seal consists of a nitrile rubber washer in metal shroud to

shield the lip from large contaminants. The seal is designed to balance drag

and protection in wet and dry environments. This can be specied by adding

the sufx C to the part number.

Additional Sealing Options can be found in the Custom Select section on pages

G-24 to G-27.
