Metric Sprockets

Metric chain sprocket sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety of sizes which includes ISO 06B, 08B, 10B, 12B, 16B and 20B chain sizes (3/8 to 1-1/4” pitch) for single, double 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 accommodate various application speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of the teeth. So all could be heat treated Hardened The teeth on request. The TL Taper Bushed Sprocket provides a true concentric fit 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 installation or removal. Once the bushing mounting screws are loosened and eliminated, the screw is usually re-used and threaded into the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a standard global design, which is why the TL sprocket is indeed versatile. Simple installation, concentric shaft fit, ideal for higher speeds and large loads plus an economical price, make this the popular choice for new styles and replacement requirements. TL sprockets are generally less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum simple bore (pilot bore) and some share finished bore sizes. Any shaft size can be done with our custom made bore and keyway capacity. Sprockets with hubs are usually fitted to the shaft as a clearance fit. They are held set up with two established screws and a keyway. Clearance fits are well-known for light loads and slow speeds. A press fit (or shrink match to the shaft) is normally preferred for higher speeds or heavier loads because they fit to the shaft more safely than a clearance suit sprocket. Based on the clearance of the shaft match, sprockets may work somewhat on the shaft causing feasible fretting or shaft wear. All standard hub sprockets are available with hardened the teeth from stock or on request. Press fits usually require the sprocket to become heated for set up to increase the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A set screw secures the key. The TL Taper Bushed Sprocket will function just like the press match sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for one, double or triple strand chain are an economical choice allowing for immediate mounting to the clients’ hub or shaft. They are most frequently regarded as for sprockets above 40 teeth and are available in an array of diameters. Plate type sprockets could be welded or bolted right 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 large diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform most of the other standard drive parts. TL Bushings are stocked in both metric and inch 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 modern solution for upgrading clearance match and press match sprockets. TL Bushings are used in a multitude of various other European and American standard 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 could be provided with 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 tooth. Larger sizes on demand. TL Bushed edition also on demand. Metric Idler and Double-Single Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally offer tension for the chain drive and can be used within a pressure arm assembly or separately mounted to put the drive. Share sizes are for sale to 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 units that must index. Customized Metric or ANSI Sprockets Custom made sprockets including large diameter metal or cast iron products for single, duplex or triple strand chain could be made to purchase. PTI typically helps to keep some stock in our European warehouse, so delivery could possibly be rather quick. 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 customized finished bore.
