HTD® Aluminum Timing Belt Pulleys at SDP/SI
Product Announcement from Stock Drive Products & Sterling Instrument - SDP/SI
Hicksville, NY -- A series of 3 mm Pitch HTD® aluminum timing belt pulleys for 6 mm (.236") belts manufactured by SDP/SI (ISO 9001 + AS9100D Registered Manufacturer) feature the patented Fairloc® integral hub fastening design which eliminates the need for conventional separate hub clamp devices.
Additionally, the choice of Fairloc® hubs offers the benefits of frequent position adjustment, while adding positive metal-to-metal fastening strength along the entire hub surface.
Identified as the A 6A23-... and A 6D23-... inch series, and A 6A23M... and A 6D23M... metric series, these HTD® pulleys are made of clear anodized aluminum alloy and are available from stock in 10 to 80 grooves. Bore sizes range from .125" to .313" in inch and 3 mm to 8 mm in metric. O.D.'s range from .346" to 2.9" in inch and 8.8 mm to 68 mm in metric. They are also available in double flange type. SDP/SI stocks a wide variety of other HTD® size pulleys in different materials and for different belt widths.
The Fairloc® integral hub fastener consists of two slots that are machined into the hub, one radially the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section. As the screw is tightened, the cantilevered section clamps the shaft securely. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque transmitting abilities. 2 mm pitch GT®2 timing belt pulleys pulleys are also available with Fairloc® Hub.
