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 standard TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in an array of diameters to accommodate various app speeds. The more 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 ask for. 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. After the bushing installation screws are loosened and taken out, the screw is re-used and threaded into the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a typical global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft suit, ideal for higher speeds and heavy loads plus a cost-effective cost, make this the favorite choice for new styles and replacement needs. TL sprockets are usually less expensive than customized or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum simple bore (pilot bore) and some stock completed bore sizes. Any shaft size is possible with our custom bore and keyway ability. Sprockets with hubs are usually suited to the shaft as a clearance match. They are held set up with two set screws and a keyway. Clearance fits are popular for light loads and gradual speeds. A press match (or shrink match to the shaft) is normally preferred for higher speeds or heavier loads as they suit to the shaft more safely than a clearance match sprocket. According to the clearance of the shaft match, sprockets may work slightly on the shaft leading to possible fretting or shaft wear. All regular 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 increase the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good 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 one, 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 an array of diameters. Plate type sprockets could be welded or bolted directly to the users’ hub keeping tools compact and light weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is frequently used to simplify installation, especially huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other regular drive components. 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 alternative for upgrading clearance suit and press suit sprockets. TL Bushings are used in a sprockets multitude of additional European and American standard drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capacity. These hub type sprockets could be provided with a finished 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 the teeth. Larger sizes available on ask for. TL Bushed edition also on request. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally provide stress for the chain drive and can be used within a stress arm assembly or individually 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 about the same sprocket to control pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Custom sprockets including large diameter steel or cast iron products for single, duplex or triple strand chain can be made to order. PTI typically retains some stock inside our European warehouse, therefore delivery could be rather quick. Additional custom made sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are obvious. All are possible with custom finished bore.
