When wear and damage occur on a shaft, SKF Speedi-Sleeves are the solution.
In order to perform their function properly, shaft seals must be seated on a smooth, round shaft face. If the shaft face becomes worn the seal can no longer perform as necessary, and, over time, will allow contaminants to enter the component and cause further damage to both the shaft and the component. Simply replacing the seal will not repair the damage to the shaft and therefore, it would be necessary to take the machine apart and grind the shaft face down until smooth again which will allow the seals to function.
Speedi-Sleeves from SKF provide a proven solution to worn shafts without disassembling the shaft or requiring new seal sizes due to grinding the shaft down. They provide a new, smooth sealing surface for the seal to sit against, while preventing further wear to the shaft face. The 99139 Speedi-Sleeve is no exception. Made with SKF’s manufacturing process and proprietary stainless-steel material, this sleeve is a perfectly engineered seal counterface surface designed to minimize wear on the sealing lip. This Speedi-Sleeve’s dimensions are:
Shaft Diameter, minimum - 34.93mm
Shaft Diameter, maximum - 35.08mm
Width - 16mm.
SKF Speedi-Sleeves have a removable flange to simplify installation. The flange can be left intact, but it should be removed in applications where it will interfere with other components so as not to cause friction heat and wear debris. The flange should also be removed in applications where it may reduce the supply of lubricant to the seal.
SKF Speedi-Sleeves like the 99139, contain imperceptible lubricant pockets. These pockets enable lubricant to reside on the sleeve and prevent dry running of the sealing lip which can lead to excessive wear.
The 99139 sleeve is thin walled (0,28 mm / 0.011 inch) and the contact surface is wear-resistant and manufactured to minimize directionality (0° ±0,05) with a finish of Ra 0,25 to 0,5µm (10 to 20µin). This is a better counterface than can often be achieved on a shaft.
