Mounted Ball Bearings
Multiple Methods Locking
BOA Concentric
BOA is a concentric locking collar clamp design that results in near-perfect
concentricity of the shaft to the 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.
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.
Eccentric Locking
Eccentric locking design incorporates a precision eccentric collar to mate with
the inner ring extension for shaft hold.
Note: The eccentric is designed for single direction of rotation and should not
be used when two direction rotation is present.
Anti-Rotation Rivet
An anti-rotation rivet prevents outer ring creep, or rotation, within the housing.
Features and Benefits
Sealing
Positive contact molded nitrile rubber contact seal with an auxiliary inger
element standard. The contact seal allows grease purge and helps keep
contamination out of the bearing while the inger provides a rotating shield
that helps direct contamination away from the seal.
