Metric Sprockets

Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide selection 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 install with standard TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in a wide range of diameters to accommodate various software speeds. The more popular sizes are stocked with hardened tooth. The C45 materials, standard steel sprockets, permits induction hardening of the teeth. So all can be high temperature treated Hardened Teeth on demand. The TL Taper Bushed Sprocket provides a true 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 installation or removal. After the bushing installation screws are loosened and removed, the screw is definitely re-used and threaded into the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a typical global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft match, ideal for higher speeds and large loads plus a cost-effective cost, make this the popular choice for new designs and replacement needs. 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 basic bore (pilot bore) plus some share finished bore sizes. Any shaft size is possible with our customized bore and keyway capability. Sprockets with hubs are usually suited to the shaft as a clearance suit. They are held set up with two set screws and a keyway. Clearance fits are popular for light loads and slower speeds. A press fit (or shrink fit to the shaft) is generally preferred for higher speeds or heavier loads as they match 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 wear. All regular hub sprockets are available with hardened tooth from stock or on ask for. Press fits usually require the sprocket to become heated for installation to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A arranged 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 a cost-effective choice allowing for immediate mounting to the customers’ hub or shaft. They are most frequently regarded for sprockets above 40 teeth and so are available in a wide variety of diameters. Plate type sprockets could be welded or bolted right to the users’ hub keeping equipment compact and light-weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often 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 many of the other standard drive parts. 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 perfect for replacements and a contemporary option for upgrading clearance fit and press suit sprockets. TL Bushings are found in a wide variety of other European and American regular drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capacity. These hub type sprockets can 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 the teeth. Larger sizes on request. TL Bushed edition also on request. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally provide stress for the chain drive and can be used 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, well-known on conveyors, allow 2 single chains about the same sprocket to control pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Customized sprockets including huge diameter metal or cast iron systems for single, duplex or triple strand chain could be made to order. PTI typically continues some stock in our European warehouse, therefore delivery could possibly be rather quick. Other customized sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are favored to insure requirements are obvious. Each is possible with customized finished bore.
