What are speedi sleeves used for?

SPEEDI-SLEEVES® were used to repair the grooved shafts without removing them from the equipment. With the addition of external V-rings, the high-pressure water was prevented from penetrating the primary seals.

How are Speedi sleeves measured?

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 is SKF Speedi-sleeve?

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 do I remove Speedi sleeve flange?

A SPEEDI-SLEEVE can be removed by applying heat to the sleeve with an electric heat blower, which will expand it enough to let it slide off the shaft without causing damage. by using a pair of wire cutters starting at or near the flange and applying a twisting motion.

How do I remove Speedi-sleeve flange?

What is a sealing sleeve?

With the limb placed in the socket, a sealing sleeve is applied over the outer upper portion of the socket and pulled up onto the thigh creating a seal against the skin. A one way expulsion valve is normally integrated at the base of the socket to allow air to expel creating a form of suction suspension.

How do you replace a Speedi sleeve?

Can a worn shaft be repaired?

Conventional Shaft Repair Methods Worn and damaged shafts are conventionally repaired using a hot process (welding/machining or hot metal spray/machining). If not carefully controlled, these conventional methods will cause residual damage to the shaft. They also require the disassembly of the machine.

Why is a shaft worn out?

Shaft Wear and Damage In the mining industry, shafts can become worn or damaged due to vibration, friction and abrasive media.
