Speedi-Sleeves are made of stainless steel and have a wall thickness of 0.254 mm (0.01 inch). Because of the extreme thinness, the diameter of the seal seating will only be increased by
about 0,5 mm so that it is possible to use replacement seals of the same size as the original.
The sleeves have a hardness of 95 HRB and a surface roughness Ra of between 0,25 to 0,5 mm. Thus they often offer a better counter face for the seal lip than the original shaft itself.
Normally, Speedi-Sleeves can be mounted immediately on the cleaned shaft.
Only in cases where the shaft exhibits deep grooving or is otherwise damaged is it advisable to first apply powdered metal epoxy filler to the grooves and other damaged areas.
All CR Speedi-Sleeves have a removable installation flange at one side for easy mounting together with the mounting tool supplied with each sleeve. The flange can be retained to act as
a flinger or can be removed easily as a pre-cut tear groove is provided.
