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, double and triple chain. These mount with standard TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in an array of diameters to support various program speeds. The popular sizes are stocked with hardened tooth. The C45 material, standard steel sprockets, allows for induction hardening of teeth. So all could be warmth treated Hardened Tooth on demand. The TL Taper Bushed Sprocket provides a accurate 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 necessary for installation or removal. Once the bushing installation screws are loosened and taken out, the screw is 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 standard global design, which is why the TL sprocket is indeed versatile. Ease of installation, concentric shaft suit, ideal for higher speeds and large loads plus a cost-effective cost, make this the favorite choice for new styles and replacement needs. 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) plus some stock completed bore sizes. Any shaft size can be done with our custom bore and keyway capability. Sprockets with hubs are usually suited to the shaft as a clearance fit. They are held in place with two set screws and a keyway. Clearance fits are well-known for light loads and slower speeds. A press suit (or shrink suit to the shaft) is normally preferred for higher speeds or heavier loads because they suit to the shaft more securely than a clearance match sprocket. According to the clearance of the shaft suit, sprockets may work somewhat on the shaft leading to feasible fretting or shaft wear. All regular hub sprockets are available with hardened teeth from share or on ask for. Press fits usually need the sprocket to end up being 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 main element. 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 single, double or triple strand chain are a cost-effective choice allowing for direct mounting to the clients’ hub or shaft. They are most frequently regarded 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 mounting, especially large diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do many 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 solution for upgrading clearance fit and press match sprockets. TL Bushings are found in a wide variety 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 given 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 tooth. Larger sizes on demand. TL Bushed version also on demand. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally offer tension for the chain drive and can be used within a stress arm assembly or individually mounted to position the drive. Share sizes are available for 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 systems that must index. Customized Metric or ANSI Sprockets Custom sprockets including huge diameter metal or cast iron units for one, duplex or triple strand chain can be made to purchase. PTI typically continues some stock in our European warehouse, so sprockets delivery could be rather quick. Various other custom sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are favored to insure requirements are clear. Each is possible with customized 
finished bore.
