Specification BikeType : City Bike Brand : SKF BulletPoint : SBDs ( Pack of 2) Aluminum Anodized Silver collar 1-1/4 inch inner diameter for tube/shaft w/ 2 Set Screws. BulletPoint1 : 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 BulletPoint2 : 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 BulletPoint3 : "SKF SPEEDI-SLEEVE. These thin-walled stainless steel shaft repair sleeves can come to immediate rescue when a crankshaft needs a new sealing surface. " BulletPoint4 : "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. " BulletPoint5 : While installation is simple, it must be done with care in order to assure proper results.

Round bore collars are commonly used as positioners, spacers, stops, and bearing surfaces.
Secure Shaft Attachment: Set screw collars are designed with a threaded hole and a set screw that tightens against the shaft, ensuring a secure attachment. This feature prevents slippage or movement of components during operation.
Adjustable Positioning: The set screw design allows for adjustable positioning along the shaft. This flexibility enables fine-tuning and precise alignment of components to achieve optimal functionality and performance.
Versatile Applications: These collars are widely used across different industries, including automotive, robotics, and manufacturing. They can be used in various equipment and machinery to secure gears, pulleys, sprockets, or other components onto shafts.
Easy Installation: These collars are easy to install on the shaft. Simply slide the collar onto the desired position and tighten the set screw using a compatible hex wrench. No additional tools or disassembly of other components are required.
