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, double and triple chain. These attach with regular TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in an array of diameters to accommodate various software speeds. The popular sizes are stocked with hardened teeth. The C45 material, standard steel sprockets, permits induction hardening of tooth. So all could be warmth treated Hardened The teeth 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 will be the only tool required for set up or removal. After the bushing installation screws are loosened and eliminated, the screw can be re-used and threaded into the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global design, which is why the TL sprocket is indeed versatile. Ease of installation, concentric shaft match, suitable for higher speeds and weighty loads plus a cost-effective cost, make this the favorite choice for new styles and replacement requirements. TL sprockets are usually less expensive than custom or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum ordinary bore (pilot bore) plus some stock finished bore sizes. Any shaft size can be done with our custom bore and keyway capacity. Sprockets with hubs are typically suited to the shaft as a clearance match. They are held in place with two set screws and a keyway. Clearance fits are well-known for light loads and slow speeds. A press fit (or shrink fit 
to the shaft) is usually favored for higher speeds or heavier loads because they suit to the shaft more safely than a clearance suit sprocket. Based on the clearance of the shaft match, sprockets may work somewhat on the shaft causing feasible fretting or shaft put on. All regular hub sprockets can be found with hardened the teeth from share or on request. Press fits usually need the sprocket to become heated for installation to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A set screw secures the main element. The TL Taper Bushed Sprocket will function just like the press fit sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for one, dual or triple strand chain are an economical choice allowing for direct mounting to the clients’ hub or shaft. They are most frequently regarded as for sprockets above 40 teeth and so are available in a wide range of diameters. Plate type sprockets could be welded or bolted directly to the users’ hub keeping devices 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 large diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do many of the other standard drive elements. 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 ideal for replacements and a contemporary remedy for upgrading clearance suit and press suit sprockets. TL Bushings are used in a wide variety of various other European and American standard drive products. Stainless Steel 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 cannot be hardened. PTI stocks sizes from ISO 06B thru 16B (3/8” -1” pitch) and from 12 to 25 & 30 the teeth. Larger sizes on request. TL Bushed version also on demand. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally offer stress for the chain drive and can be utilized within a tension arm assembly or separately mounted to position the drive. Stock sizes are available for 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. Custom Metric or ANSI Sprockets Customized sprockets including large diameter steel or cast iron products for one, duplex or triple strand chain can be made to order. PTI typically continues some stock in our European warehouse, therefore delivery could be rather quick. Various other custom sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are obvious. Each is possible with custom finished bore.
