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 standard TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide variety of diameters to support various software speeds. The more popular sizes are stocked with hardened the teeth. The C45 materials, standard steel sprockets, permits induction hardening of teeth. So all could be temperature treated Hardened The teeth on ask for. 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. After the bushing mounting screws are loosened and removed, the screw is 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 typical global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft fit, ideal for higher speeds and weighty loads plus an economical cost, make this the favorite choice for new designs and replacement requirements. TL sprockets are usually less expensive than customized or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum plain bore (pilot bore) and 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 match. They are held set up with two established screws and a keyway. Clearance fits are popular for light loads and slower speeds. A press match (or shrink suit to the shaft) is normally favored for higher speeds or heavier loads as they suit to the shaft more securely than a clearance match sprocket. With respect to the clearance of the shaft suit, sprockets may work somewhat on the shaft causing possible fretting or shaft wear. All standard hub sprockets are available with hardened teeth from share or on request. Press fits usually need the sprocket to end up being heated for set up to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A arranged screw secures the key. The TL Taper Bushed Sprocket will function just like the press suit sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for solitary, double or triple strand chain are an economical choice allowing for immediate mounting to the customers’ 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 can be welded or bolted directly to the users’ hub keeping apparatus 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 frequently 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 do 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 well suited for replacements and a contemporary alternative for upgrading clearance suit and press match sprockets. TL Bushings are found in a wide variety of additional European and American regular 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 finished 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 the teeth. Larger sizes available on demand. TL Bushed version also on ask for. Metric Idler and Double-Solitary 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 used within a pressure 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, well-known on conveyors, allow 2 single chains about the same sprocket to regulate pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Custom sprockets including huge diameter steel or cast iron devices for one, duplex or triple strand chain can be made to purchase. PTI typically continues some stock inside our European warehouse, so delivery could possibly be rather quick. Other custom sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are favored to insure requirements are clear. Each is possible with custom finished bore.
