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 mount with regular 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 accommodate various app speeds. The popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, allows for induction hardening of teeth. So all could be warmth treated Hardened Tooth on ask for. The TL Taper Bushed Sprocket offers a accurate concentric fit 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 set up or removal. Once the bushing mounting screws are loosened and eliminated, 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 explains why the TL sprocket is indeed versatile. Simple installation, concentric shaft suit, suitable for higher speeds and heavy loads plus an economical price, make this the favorite choice for new styles and replacement requirements. TL sprockets are usually less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum plain bore (pilot bore) and some stock completed bore sizes. Any shaft size can be done with our custom made bore and keyway capacity. Sprockets with hubs are typically fitted to the shaft as a clearance fit. They are held in place with two established screws and a keyway. Clearance fits are well-known for light loads and slow speeds. A press match (or shrink suit to the shaft) is usually favored for higher speeds or heavier loads because they suit to the shaft more securely than a clearance match sprocket. With respect to 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 teeth from share or on demand. Press fits usually need the sprocket to be heated for set up to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A set 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 one, double or triple strand chain are an economical choice allowing for direct mounting to the clients’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and are available in an array of diameters. Plate type sprockets can 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 installation, especially huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other regular drive components. 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 well suited for replacements and a modern answer for upgrading clearance suit and press match sprockets. TL Bushings are used in a multitude of various other European and American standard drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capability. These hub type sprockets could 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 teeth. Larger sizes available on ask for. TL Bushed version also on ask for. 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 stress 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, popular on conveyors, allow 2 single chains on a single sprocket to regulate pairs of rolls or drive devices that must index. Customized Metric or ANSI Sprockets Custom made sprockets including large diameter steel or cast iron devices for solitary, duplex or triple strand chain can be made to purchase. PTI typically maintains some stock inside our European warehouse, so delivery could be rather quick. Various other custom made sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are clear. All are possible with custom finished bore.
