Brand: SKF ID: 99487 MADE IN: USA DESCRIPTION Item Number 99487 SKF EAN 85311042963 Category CR Axle Repair / Seal Weight and Dimensions Inner (d) MM 123.83 Inner (d) Inch 4.875 Weight (kg) 0.256 SPEEDI-SLEEVE The SKF SPEEDI-SLEEVE is a fast and effective way to refinish worn shaft. It's quicker than remetalizing or regrinding, and provides an improved sealing system. The outside surface of an SKF SPEEDI-SLEEVE forms an ideal sealing surface. Many popular regrinding and refinishing techniques produce a surface that cannot be properly sealed The standard range of SKF SPEEDISLEEVE sizes covers shaft diameters from .472” to 8” (12 mm to 200 mm). The SKF SPEEDI-SLEEVE is thinwalled, 0.011” (0,28 mm), and made of high quality stainless steel. The contact surface is wearresistant with a finish of Ra 10 to 20 µin (0,25 to 0,5 µm). No expensive machining or preparation is required before mounting. Downtime is reduced since installation only takes a few minutes "SKF SPEEDI-SLEEVE. These thin-walled stainless steel shaft repair sleeves can come to immediate rescue when a crankshaft needs a new sealing surface. " "Low in cost, a SPEEDI-SLEEVE is slipped over the worn area quickly and easily, and provides a surface that is actually harder than that of a new shaft. The same size seal (as the one being replaced) fits snugly onto the new surface. And each SPEEDI-SLEEVE comes as a kit with a disposable installation tool. " While installation is simple, it must be done with care in order to assure proper results. An installation tool is packaged with every sleeve Here's how to install an SKF SPEEDI-SLEEVE 1 Clean the seal counter surface on the shaft. File down any burrs or rough spots. 2 Measure the diameter where the sleeve will be positioned on an unworn portion of the shaft. Measure in three positions and average the readings (to make sure the shaft is within recommended specifications). If the mean diameter is within the range for a given sleeve size, there is sufficient press fit built into the sleeve to prevent it from sliding or spinning without using an adhesive. 3 Determine where the sleeve must be positioned to cover the seal wear track. Measure to the exact point, or mark directly on the surface. The sleeve must be placed over the worn area, not just bottomed or left flush with the end of the shaft. 4 Shallow wear grooves do not require filling. Optionally, a light layer of a non-hardening sealant, e.g., can be applied to the inside diameter surface of the sleeve. Clean away sealant that migrates to the shaft or sleeve outside diameter surface. 5 If the shaft is deeply scored, fill the groove with a powdered metal epoxy type filler. Install the sleeve before the filler hardens, allowing the sleeve to wipe off any excess filler. Clean away any remaining filler from the sleeve outside diameter surface. 6
