Metric Sprockets

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, double and triple chain. These attach with standard TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide selection of diameters to accommodate various application speeds. The more popular sizes are stocked with hardened tooth. The C45 materials, standard steel sprockets, allows for induction hardening of the teeth. So all can be high temperature treated Hardened The teeth on request. The TL Taper Bushed Sprocket provides a accurate concentric fit 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 necessary for installation or removal. After the bushing mounting screws are loosened and removed, the screw is definitely re-used and threaded in to the bushing removal hole. Tightening the removal screw will carefully loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a standard global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft suit, suitable for higher speeds and weighty loads plus an economical price, make this the favorite choice for new designs and replacement requirements. TL sprockets are generally less expensive than customized or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum simple bore (pilot bore) plus some stock completed bore sizes. Any shaft size can be done with our customized bore and keyway capability. Sprockets with hubs are usually suited to the shaft as a clearance match. They are held set up with two set screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press match (or shrink suit to the shaft) is normally favored for higher speeds or heavier loads because they fit to the shaft more securely than a clearance match sprocket. Depending on the clearance of the shaft match, sprockets may work slightly on the shaft leading to feasible fretting or shaft use. All regular hub sprockets are available with hardened tooth from stock or on demand. Press fits usually need the sprocket to end up being 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 suit sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for solitary, dual or triple strand chain are an economical choice allowing for direct mounting to the clients’ hub or shaft. They are most frequently regarded for sprockets above 40 teeth and are available in a wide variety of diameters. Plate type sprockets can be welded or bolted right to the users’ hub keeping devices compact and light-weight. They are available in single, dual and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is frequently used to simplify mounting, especially large diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform most of the other standard 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 modern answer for upgrading clearance fit and press suit sprockets. TL Bushings are found in a wide variety of additional European and American standard drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capacity. 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 on demand. TL Bushed version also on demand. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally provide stress for the chain drive and can be used within a tension arm assembly or separately mounted to put 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 control pairs of rolls or drive systems that must index. Customized Metric or ANSI Sprockets Customized sprockets including huge diameter steel or cast iron models for solitary, duplex or triple strand chain can be made to purchase. PTI typically keeps some stock inside our European warehouse, therefore 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.
