Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide selection of sizes which includes ISO 06B, 08B, 10B, 12B, 16B and 20B chain sizes (3/8 to 1-1/4” pitch) for single, dual and triple chain. These install with standard TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide range of diameters to accommodate various app speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, allows for induction hardening of tooth. So all can be heat treated Hardened The teeth on ask for. The TL Taper Bushed Sprocket provides a true concentric suit to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft safely. Standard hex wrenches will be the only tool necessary for set up or removal. After the bushing mounting screws are loosened and removed, the screw is certainly re-used and threaded in to the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a typical global design, which is why the TL sprocket is so versatile. Simple installation, concentric shaft match, ideal for higher speeds and large loads plus an economical price, make this the favorite choice for new styles and replacement requirements. TL sprockets are usually less expensive than custom or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum simple bore (pilot bore) plus some share finished bore sizes. Any shaft size is possible with our custom bore and keyway capability. Sprockets with hubs are typically fitted to the shaft as a clearance fit. They are held set up with two set screws and a keyway. Clearance fits are well-known for light loads and gradual speeds. A press suit (or shrink fit to the shaft) is usually preferred for higher speeds or heavier loads as they match to the shaft more safely than a clearance suit sprocket. Based on the clearance of the shaft fit, sprockets may work slightly on the shaft leading to possible fretting or shaft wear. All standard hub sprockets can be found with hardened teeth from stock or on request. Press fits usually need 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 established screw secures the key. 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 immediate mounting to the customers’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and so are available in a wide variety of diameters. Plate type sprockets could be welded or bolted right to the users’ hub keeping equipment compact and light weight. They can be purchased in single, dual and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, especially huge 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 elements. TL Bushings are stocked in both metric and in . 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 perfect for replacements and a modern remedy for upgrading clearance match and press fit sprockets. TL Bushings are used in a wide variety of various other European and American standard drive products. Stainless Steel Metric Sprockets Stainless Steel (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 edition also on ask for. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally offer pressure for the chain drive and can be utilized within a tension arm assembly or individually mounted to put the drive. Share sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known on conveyors, allow 2 single chains about the same sprocket to regulate pairs of rolls or drive units that must index. Custom Metric or ANSI Sprockets Custom made sprockets including large diameter metal or cast iron devices for one, duplex or triple strand chain could be made to purchase. PTI typically will keep some stock inside our European warehouse, therefore delivery could possibly be rather quick. Other customized sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are favored to insure requirements are obvious. All are possible with customized finished bore.
