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 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 variety of diameters to accommodate various app 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 temperature treated Hardened Teeth on demand. The TL Taper Bushed Sprocket offers a accurate concentric suit 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 installation or removal. Once the bushing mounting screws are loosened and eliminated, the screw is definitely re-used and threaded in to the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a standard global chain sprocket design, which explains why the TL sprocket is indeed versatile. Ease of installation, concentric shaft match, ideal for higher speeds and heavy loads plus a cost-effective cost, make this the popular choice for new styles and replacement needs. TL sprockets are generally less expensive than customized or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum basic bore (pilot bore) plus some stock completed bore sizes. Any shaft size can be done with our custom made bore and keyway capability. Sprockets with hubs are typically suited to the shaft as a clearance match. They are held set up with two arranged screws and a keyway. Clearance fits are popular for light loads and gradual speeds. A press suit (or shrink fit to the shaft) is normally favored for higher speeds or heavier loads as they match to the shaft more safely than a clearance fit sprocket. With respect to the clearance of the shaft match, sprockets may work slightly on the shaft leading to feasible fretting or shaft wear. All regular hub sprockets are available with hardened the teeth from share or on request. 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 tight grip. A established screw secures the key. The TL Taper Bushed Sprocket will function just like the press match 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 immediate mounting to the customers’ hub or shaft. They are most regularly regarded for sprockets above 40 teeth and so are available in a wide variety of diameters. Plate type sprockets can be welded or bolted directly to the users’ hub keeping products compact and light-weight. They can be purchased in single, dual 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 typical TL bushings as perform many of the other regular 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 ideal for replacements and a contemporary answer for upgrading clearance fit and press suit sprockets. TL Bushings are found in a multitude of additional 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 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 ask for. TL Bushed edition also on demand. Metric Idler and Double-Solitary 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 pressure arm assembly or individually 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 about the same sprocket to control pairs of rolls or drive products that must index. Customized Metric or ANSI Sprockets Customized sprockets including huge diameter steel or cast iron devices for solitary, duplex or triple strand chain could be made to purchase. PTI typically maintains some stock in our European warehouse, therefore delivery could possibly be rather quick. Additional customized sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are obvious. All are possible with custom finished bore.
