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 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 program speeds. The popular sizes are stocked with hardened tooth. The C45 material, standard steel sprockets, permits induction hardening of teeth. So all can be temperature treated Hardened Teeth on ask for. The TL Taper Bushed Sprocket provides a true concentric suit 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 necessary for set up or removal. After 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 gently loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a typical global design, which explains why the TL sprocket is so versatile. Ease of installation, concentric shaft match, ideal for higher speeds and weighty loads plus an economical cost, make this the favorite choice for new designs and replacement needs. TL sprockets are generally less expensive than custom or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum ordinary bore (pilot bore) plus some stock completed bore sizes. Any shaft size can be done with our custom made bore and keyway ability. 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 well-known for light loads and sluggish speeds. A press match (or shrink match to the shaft) is usually favored for higher speeds or heavier loads because they fit to the shaft more safely than a clearance suit sprocket. Depending on the clearance of the shaft match, sprockets may work somewhat on the shaft causing feasible fretting or shaft put on. All standard hub sprockets are available with hardened tooth from share or on ask for. 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 good grip. A established screw secures the main element. The TL Taper Bushed Sprocket will function like the press fit sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for single, dual or triple strand chain are an economical choice allowing for direct mounting to the clients’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and so are available in a wide range of diameters. Plate type sprockets can be welded or bolted right to the users’ hub keeping devices compact and light weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is frequently used to simplify installation, especially large diameter sprockets. PTI stocks standard 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 ” 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 modern alternative for upgrading clearance suit and press fit sprockets. TL Bushings are used in a wide variety of other 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 can be given 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 tooth. Larger sizes available 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 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 control pairs of rolls or drive devices that must index. Custom Metric or ANSI Sprockets Customized sprockets including large diameter metal or cast iron products for solitary, duplex or triple strand chain could be made to order. PTI typically retains some stock inside our European warehouse, therefore 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. All are possible with customized finished bore.
