 Seal Guard

o Redesigned and material upgraded to greatly improve the installation and long term fit on

the bearing cap assembly.

o Performance results:

 Virtually eliminates the potential for cracking during installation or operation.
 Improved performance in extreme temperatures.
 Eliminates the potential for outside contaminants from reaching the bearings.

 Trunion Seal on pre lube U-Joints

o The design of triple lip seal has been changed.
o Performance results:

 Instances of loss of small amounts of

grease has been reduced by >50%.

 Thrust Washer design changes

o The thrust washer is now a 2-piece assembly (a

thrust washer and a spacer). The spacer is
machined with 3 grooves per side.

o Performance results:

 The addition of a spacer allows for improved rotation of the journal cross and the

needle bearings.

 Improved distribution of grease.
 Reduced potential for misaligned needle bearings.

 Journal Cross Design changes

o The chamfer at the end of the trunion has been increased and seal guard retention ridge

has been redesigned.

o Performance results:

 Reduced stresses on the seal guard.
 Reduced journal cross stress levels.
 Improved needle bearing retention.

Thank you for your continued support of Spicer U-joints.
