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, dual and triple chain. These install with regular TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in a wide range of diameters to accommodate various program speeds. The popular sizes are stocked with hardened the teeth. The C45 material, standard steel sprockets, allows for induction hardening of tooth. So all could be temperature treated Hardened Tooth on request. The TL Taper Bushed Sprocket provides a accurate concentric match to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft securely. Standard hex wrenches are the only tool required for set up or removal. Once the bushing mounting screws are loosened and removed, the screw is certainly re-used and threaded into 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 explains why the TL sprocket is so versatile. Simple installation, concentric shaft match, 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 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 share completed bore sizes. Any shaft size is possible with our customized bore and keyway capability. Sprockets with hubs are typically fitted to the shaft as a clearance fit. They are held set up with two arranged screws and a keyway. Clearance fits are well-known for light loads and sluggish speeds. A press suit (or shrink suit to the shaft) is usually favored for higher speeds or heavier loads as they fit to the shaft more securely than a clearance fit sprocket. Based on the clearance of the shaft match, sprockets may work slightly on the shaft causing possible fretting or shaft put on. All standard hub sprockets can be found with hardened teeth from share or on demand. Press fits usually require the sprocket to be heated for installation to increase 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 just like the press match sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for solitary, double 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 so are available in an array of diameters. Plate type sprockets can be welded or bolted directly to the users’ hub keeping equipment compact and light-weight. They can be purchased in single, double and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is frequently 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 perform many of the other regular drive components. TL Bushings are stocked in both metric and inch 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 contemporary alternative for upgrading clearance match and press match sprockets. TL Bushings are used in a multitude of various other European and American regular drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capacity. These hub type sprockets can be provided with 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 tooth. Larger sizes on ask for. TL Bushed version also on request. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally provide tension for the chain drive and can be utilized within a tension arm assembly or individually mounted to put the drive. Stock sizes are for sale to 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 units that must index. Customized Metric or ANSI Sprockets Custom made sprockets including huge diameter steel or cast iron products for one, duplex or triple strand chain can be made to order. PTI typically keeps some stock inside our European warehouse, so delivery could possibly be rather quick. Additional custom sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are clear. Each is possible with custom finished bore.
