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 mount 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 selection of diameters to support various app speeds. The more 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 suit 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 required for installation or removal. Once the bushing mounting screws are loosened and taken out, the screw can be re-used and threaded in to the bushing removal hole. Tightening the removal screw will lightly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global design, which explains why the TL sprocket is indeed versatile. Simple installation, concentric shaft fit, suitable for higher speeds and weighty loads plus an economical cost, make this the popular choice for new designs and replacement needs. TL sprockets are usually less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum simple bore (pilot bore) plus some share finished 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 in place with two set screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press fit (or shrink suit to the shaft) is normally preferred for higher speeds or heavier loads because they suit to the shaft more safely than a clearance fit sprocket. Depending on the clearance of the shaft fit, sprockets may work slightly on the shaft leading to feasible fretting or shaft use. All standard hub sprockets are available with hardened teeth from share or on request. Press fits usually require the sprocket to become heated for installation to expand 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 like the press match sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for single, dual 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 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 can be purchased in single, dual 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 standard drive elements. TL Bushings are stocked in both metric and ” 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 contemporary alternative for upgrading clearance suit and press suit sprockets. TL Bushings are used in a wide variety of other European and American standard drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down ability. These hub type sprockets could 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 teeth. Larger sizes available on request. TL Bushed edition 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 pressure arm assembly or individually mounted to put 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 products that must index. Customized Metric or ANSI Sprockets Custom sprockets including huge diameter metal or cast iron devices for single, duplex or triple strand chain can be made to purchase. PTI typically retains some stock in our European warehouse, so delivery could possibly be rather quick. Additional custom made sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are favored to insure requirements are obvious. Each is possible with custom finished bore.
