Metric 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 mount with regular TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in a wide range of diameters to support various application speeds. The popular sizes are stocked with hardened the teeth. The C45 materials, standard steel sprockets, allows for induction hardening of the teeth. So all can be high temperature treated Hardened Teeth on request. 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 are the only tool required for installation or removal. After 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 gently loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a typical global design, which is why the TL sprocket is indeed versatile. Simple installation, concentric shaft suit, ideal for higher speeds and large loads plus a cost-effective price, make this the favorite choice for new designs and replacement requirements. TL sprockets are usually less expensive than custom or completed 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 is possible with our custom bore and keyway capacity. Sprockets with hubs are typically suited to the shaft as a clearance suit. They are held in place with two set screws and a keyway. Clearance fits are well-known for light loads and sprockets gradual speeds. A press suit (or shrink suit to the shaft) is usually preferred for higher speeds or heavier loads because they fit to the shaft more safely than a clearance fit sprocket. According to the clearance of the shaft suit, sprockets may work slightly on the shaft leading to feasible fretting or shaft use. All standard hub sprockets are available with hardened tooth from stock or on ask for. Press fits usually need the sprocket to become heated for set up to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A arranged 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, dual or triple strand chain are an economical choice allowing for direct mounting to the clients’ hub or shaft. They are most regularly 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 gear 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 installation, especially large diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do 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 ideal for replacements and a contemporary remedy for upgrading clearance fit and press fit sprockets. TL Bushings are used in a multitude of other European and American standard drive products. Stainless Steel Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capacity. These hub type sprockets could be provided with a completed 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-Single Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally provide stress for the chain drive and can be used within a stress arm assembly or separately mounted to put the drive. Stock sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, popular on conveyors, allow 2 single chains about the same sprocket to regulate pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Custom sprockets including huge diameter metal or cast iron models for one, duplex or triple strand chain can be made to purchase. PTI typically continues some stock in our European warehouse, therefore delivery could possibly be rather quick. Additional customized sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are clear. Each is possible with custom finished bore.
