What does a Speedi-sleeve do?
What does a Speedi-sleeve do?
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.
How do you size a Speedi-sleeve?
To determine the appropriate sleeve size, it is first necessary to clean the shaft carefully. The diameter of an undamaged section of the seal counterface should then be measured on at least three different planes. The arithmetical mean of these measurements determines the size of SKF SPEEDI-SLEEVE.
What are speedi sleeves made of?
stainless steel
The new generation SKF Speedi-Sleeve uses a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. The proprietary material provides increased strength and excellent ductility properties of the sleeve.
How thick are speedi sleeves?
The Speedi-Sleeve is thin-walled, 0.011 in (0.28 mm), and made of high quality stainless steel. The contact surface is wear-resistant and machined to minimize directionality (0° ±0.05) with a finish of Ra 10 to 20 µin (0.25 to 0.5 µm), depending on size.
What is a speedi seal?
SPEEDI-SLEEVE® THE SPEEDI-SLEEVE® CONCEPT. the quickest and sensible way. to repair worn shafts. To seal efficiently, radial shaft seals must run against a smooth round surface – the seal counterface.
What is a sleeve and seal?
A Sleeve N Seal is a thin-walled metal ring ~1″ deep with an accompanying tube of “seal”. It comes with some timing cover gasket sets. To install it, you heat the ring up in the oven on 500 degrees for 10 minutes.
What is a ready sleeve?
Timken offers Redi-Sleeves, which are precision stainless steel wear sleeves designed to be pressed onto a shaft for an enhanced sealing surface. Redi-Sleeves are fast, inexpensive repair options for grooved or worn shafts.
What is pump shaft sleeve?
A shaft sleeve acts as a shield for the shaft assembly in pumps and compressors. A shaft sleeve is a hollow metal tube, cylindrical in shape, which is mounted over a shaft and shaft assembly to protect it in a corrosive environment. Shaft sleeves are commonly found in single stage pumps.
What is a repair sleeve?
are metallic sleeves and are used as counterface replacement for radial shaft seals. Applications. Shaft repair sleeves are pushed onto shafts to repair the worn counterface for radial shaft seals. They are a quick and cost-effective alternative to replacing or often costly reworking of the shaft.
What are SPEEDI sleeves?
Also known as speedi sleeves, use these to repair and protect worn shafts for a smooth sealing surface without machining. Each sleeve comes with an installation tool.
What makes the SKF SPEEDI-sleeve different?
The new generation SKF Speedi-Sleeve uses a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. The proprietary material provides increased strength and excellent ductility properties of the sleeve.
What is the standard size range for shaft sleeves?
The standard size range covers sleeves for shaft diameters from 11,99 to 203,33 mm (0.472 to 8 in.). Depending on production quantities, non-standard sizes can be manufactured. Each sleeve is designed to fit a specific shaft diameter range, usually above and below the nominal shaft diameter.
How do I install the sleeve?
Each sleeve comes with an installation tool. To install, place the installation tool around the sleeve and gently tap the installation tool until the sleeve covers the worn shaft surface. For technical drawings and 3-D models, click on a part number. Max.
