Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety of sizes including 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 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 program speeds. The popular sizes are stocked with hardened tooth. The C45 material, standard steel sprockets, allows for induction hardening of the teeth. So all could be heat treated Hardened The teeth on demand. 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 will be the only tool necessary for installation or removal. Once the bushing installation screws are loosened and removed, the screw is certainly re-used and threaded into the bushing removal hole. Tightening the removal screw will carefully loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global design, which is why the TL sprocket is so versatile. Simple installation, concentric shaft suit, ideal for higher speeds and large loads plus a cost-effective price, make this the popular 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 is possible with our custom made bore and keyway capacity. Sprockets with hubs are usually fitted to the shaft as a clearance suit. They are held set up with two established screws and a keyway. Clearance fits are popular for light loads and gradual speeds. A press suit (or shrink match to the shaft) is usually favored for higher speeds or heavier loads as they match to the shaft more safely than a clearance match sprocket. With respect to the clearance of the shaft match, sprockets may work somewhat on the shaft causing feasible fretting or shaft use. All regular hub sprockets are available with hardened the teeth from stock or on demand. Press fits usually require the sprocket to become 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 key. The TL Taper Bushed Sprocket will function like the press match sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for solitary, double or triple strand chain are an economical choice allowing for immediate mounting to the customers’ hub or shaft. They are most regularly regarded as for sprockets above 40 teeth and are available in a wide selection 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, dual and triple tooth configurations aswell. 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 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 modern alternative for upgrading clearance match and press suit sprockets. TL Bushings are used in a wide variety of additional European and American regular drive products. Stainless Steel Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capability. 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 teeth. Larger sizes on demand. TL Bushed version also on demand. Metric Idler and Double-Single 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 separately mounted to position the drive. Stock sizes are for sale to ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known on conveyors, allow 2 single chains on a single sprocket to regulate pairs of rolls or drive models that must index. Customized Metric or ANSI Sprockets Custom sprockets including huge diameter steel or cast iron devices for single, duplex or triple strand chain could be made to purchase. PTI typically continues some stock inside our European warehouse, so delivery could be rather quick. Additional customized 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.
