SKF Speed Sleeve, 39.93mm to 40.09mm Shaft Diameter, 13mm Seal Seat Width - 99157 Avoid the need for shaft repairs with this bearing speed sleeve from SKF. If your shaft has been damaged by abrasion, contaminants or lack of lubrication, you don't need to replace it. Instead, position this device over the damaged area to get your machinery operational immediately and minimise disruption. The stainless steel sleeve provides a smooth surface designed for radial shaft seals. It's sized to fit a narrow range of shaft sizes, which means it offers tolerance for variations. • Proprietary stainless steel material for increased strength and ductility
• Wear-resistant contact surface extends service life
• Thin 0.28mm walls mean you keep your original seal size
• Removable flange for easy installation Applications • Rolling mills
• Primary metal plants
• Chemical and mineral plants How do I know the sleeve size I need? Carefully clean the shaft, then find an undamaged section of the seal counterface and measure the diameter on at least three different planes. If the mean value of the measurements is inside the range listed in the product table, the sleeve will fit tightly and won’t need an adhesive.
