Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety of sizes including ISO 06B, 08B, 10B, 12B, 16B and 20B chain sizes (3/8 to 1-1/4” pitch) for single, dual and triple chain. These attach with regular TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide variety of diameters to support various application speeds. The more popular sizes are stocked with hardened the teeth. The C45 material, standard steel sprockets, allows for induction hardening of the teeth. So all can be heat treated Hardened Tooth on request. The TL Taper Bushed Sprocket offers a true concentric match to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft safely. Standard hex wrenches are the only tool necessary for set up or removal. After the bushing installation screws are loosened and removed, the screw can be re-used and threaded into the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global design, which is why the TL sprocket is indeed versatile. Ease of installation, concentric shaft suit, suitable for higher speeds and weighty loads plus an economical cost, make this the popular choice for new styles and replacement needs. TL sprockets are generally less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum ordinary bore (pilot bore) plus some share finished bore sizes. Any shaft size is possible with our customized bore and keyway capacity. Sprockets with hubs are typically suited to the shaft as a clearance match. They are held set up with two established screws and a keyway. Clearance fits are well-known for light loads and gradual speeds. A press fit (or shrink match to the shaft) is generally preferred for higher speeds or heavier loads because they suit to the shaft more securely than a clearance suit sprocket. With respect to the clearance of the shaft fit, sprockets may work slightly on the shaft leading to possible fretting or shaft put on. All regular hub sprockets are available with hardened teeth from stock or on demand. Press fits usually require the sprocket to end up being heated for installation to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A established screw secures the main element. The TL Taper Bushed Sprocket will function just like the press fit sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for single, double or triple strand chain are an economical choice allowing for direct mounting to the customers’ hub or shaft. They are most frequently regarded for sprockets above 40 teeth and are available in an array of diameters. Plate type sprockets can be welded or bolted directly to the users’ hub keeping apparatus compact and light-weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially huge diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do many of the other regular drive components. TL Bushings are stocked in both metric and ” bores. TL Bushings for Weld-On-Hubs or TL Bushed Sprockets TL Taper Bushings for Weld-OnHubs and sprockets are stocked from 1008 thru 5050 sizes covering 5” or 125mm shaft sizes. TL Bushings are well suited for replacements and a contemporary answer for upgrading clearance suit and press suit sprockets. TL Bushings are used in a multitude of other European and American regular drive products. Stainless Steel Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down ability. These hub type sprockets can be given a finished bore and keyway. Stainless Sprockets cannot be hardened. PTI stocks sizes from ISO 06B thru 16B (3/8” -1” pitch) and from 12 to 25 & 30 the teeth. Larger sizes available on ask for. TL Bushed version also on request. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally provide pressure for the chain drive and can be utilized within a tension arm assembly or separately mounted to position the drive. Share sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, popular on conveyors, allow 2 single chains on a single sprocket to control pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Custom sprockets including huge diameter steel or cast iron devices for solitary, duplex or triple strand chain could be made to purchase. PTI typically keeps some stock in our European warehouse, therefore delivery could possibly be rather quick. Various other custom sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are obvious. All are possible with custom finished bore.
