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 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 selection of diameters to support various app speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of tooth. So all could be heat treated Hardened Teeth on demand. The TL Taper Bushed Sprocket offers a accurate concentric match to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft securely. Standard hex wrenches will be the only tool required for installation or removal. After the bushing installation screws are loosened and eliminated, the screw is usually re-used and threaded in to 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 explains why the TL sprocket is so versatile. Ease of installation, concentric shaft suit, ideal for higher speeds and weighty loads plus a cost-effective price, make this the popular choice for new styles and replacement requirements. TL sprockets are usually less expensive than customized or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum ordinary bore (pilot bore) and some stock completed bore sizes. Any shaft size is possible with our custom made bore and keyway capability. Sprockets with hubs are usually suited to the shaft as a clearance match. They are held set up with two arranged screws and a keyway. Clearance fits are well-known for light loads and slower speeds. A press fit (or shrink suit to the shaft) is usually preferred for higher speeds or heavier loads as they fit to the shaft more safely than a clearance match sprocket. Depending on the clearance of the shaft fit, sprockets may work slightly on the shaft leading to possible fretting or shaft use. All standard hub sprockets can be found with hardened the teeth from stock or on ask for. Press fits usually require 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 good grip. A established screw secures the main element. The TL Taper Bushed Sprocket will function like the press match sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for one, double or triple strand chain are a cost-effective choice allowing for immediate mounting to the clients’ 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 can be welded or bolted right to the users’ hub keeping devices compact and light weight. They can be purchased in single, dual and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform many of the other regular 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 well suited for replacements and a modern option for upgrading clearance fit and press suit sprockets. TL Bushings are found 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 ability. These hub type sprockets can be given a completed 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 available on ask for. TL Bushed edition also on demand. Metric Idler and Double-Single 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 utilized within a pressure arm assembly or individually 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 on a single sprocket to regulate pairs of rolls or drive products that must index. Customized Metric or ANSI Sprockets Customized sprockets including huge diameter metal or cast iron units for single, duplex or triple strand chain can be made to order. PTI typically will keep some stock inside our European warehouse, therefore 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. All are possible with customized finished bore.
