Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide selection 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 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in an array of diameters to accommodate various application speeds. The more popular sizes are stocked with hardened the teeth. The C45 materials, standard steel sprockets, permits induction hardening of tooth. So all could be temperature treated Hardened Teeth on request. 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 safely. Standard hex wrenches will be the only tool required for set up or removal. Once the bushing mounting screws are loosened and taken out, the screw is re-used and threaded into the bushing removal hole. Tightening the removal screw will lightly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a standard global 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 favorite choice for new styles and replacement needs. TL sprockets are usually less expensive than custom or finished 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 ability. Sprockets with hubs are usually fitted to the shaft as a clearance suit. They are held in place with two arranged screws and a keyway. Clearance fits are popular for light loads and gradual speeds. A press match (or shrink match to the shaft) is usually favored for higher speeds or heavier loads because they suit to the shaft more safely than a clearance fit sprocket. Based on the clearance of the shaft match, sprockets may work slightly on the shaft leading to feasible fretting or shaft wear. All standard hub sprockets can be found with hardened teeth 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 established screw secures the main element. The TL Taper Bushed Sprocket will function like the press match sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for single, double or triple strand chain are a cost-effective 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 could be welded or bolted right to the users’ hub keeping products 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 typical TL bushings as do most 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 well suited for replacements and a modern answer for upgrading clearance match and press suit sprockets. TL Bushings are found in a multitude 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 ability. These hub type sprockets can be provided with 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 tooth. Larger sizes on ask for. TL Bushed edition also on request. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally offer pressure for the chain drive and can be used within a stress arm assembly or individually mounted to put 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 on a single sprocket to regulate pairs of rolls or drive products that must index. Custom Metric or ANSI Sprockets Custom made sprockets including huge diameter steel or cast iron products for one, 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. Other custom made sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are favored to insure requirements are clear. Each is possible with customized finished bore.
