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 can be found in an array of diameters to support various program speeds. The popular sizes are stocked with hardened the teeth. The C45 material, standard steel sprockets, permits induction hardening of tooth. So all could be high temperature treated Hardened The teeth on demand. The TL Taper Bushed Sprocket provides a accurate concentric match to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft securely. Standard hex wrenches are the only tool necessary for installation or removal. Once the bushing installation screws are loosened and removed, the screw is usually re-used and threaded in to the bushing removal hole. Tightening the removal screw will carefully loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global design, which explains why the TL sprocket is so versatile. Simple installation, concentric shaft suit, ideal for higher speeds and large loads plus a cost-effective price, make this the popular choice for new styles and replacement requirements. TL sprockets are usually 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) and some share finished bore sizes. Any shaft size can be done with our custom made bore and keyway capability. Sprockets with hubs are typically fitted to the shaft as a clearance suit. They are held set up with two established screws and a keyway. Clearance fits are popular for light loads and slower speeds. A press suit (or shrink match to the shaft) is normally favored for higher speeds or heavier loads as they fit to the shaft more securely than a clearance fit sprocket. Depending on 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 can be found with hardened teeth from stock or on request. Press fits usually require the sprocket to become heated for set up to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A set screw secures the key. The TL Taper Bushed Sprocket will function just like the press fit sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for solitary, dual or triple strand chain are an economical choice allowing for direct mounting to the customers’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and so are available in a wide selection of diameters. Plate type sprockets can be welded or bolted right to the users’ hub keeping gear compact and light-weight. They are available in single, dual and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, especially large diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other regular drive parts. 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 ideal for replacements and a contemporary option for upgrading clearance match and press suit sprockets. TL Bushings are used in a wide variety of additional European and American regular drive products. Stainless Steel Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capacity. These hub type sprockets could be provided with a completed bore and keyway. Stainless Sprockets can’t be hardened. PTI stocks sizes from ISO 06B thru 16B (3/8” -1” pitch) and from 12 to 25 & 30 tooth. Larger sizes on request. TL Bushed version also on request. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally provide pressure for the chain drive and can be utilized within a pressure arm assembly or individually mounted to put the drive. Stock sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known 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 Customized sprockets including huge diameter metal or cast iron models for solitary, duplex or triple strand chain can be made to order. PTI typically will keep some stock inside our European warehouse, so delivery could possibly be rather quick. Various other customized sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are obvious. All are possible with customized finished bore.
