Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety 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 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 software speeds. The popular sizes are stocked with hardened tooth. The C45 materials, standard steel sprockets, allows for induction hardening of tooth. So all could be high temperature treated Hardened The teeth on ask for. The TL Taper Bushed Sprocket offers a true concentric fit to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft safely. Standard hex wrenches are the only tool required for set up or removal. Once 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 lightly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a typical global design, which is why the TL sprocket is indeed versatile. Ease of installation, concentric shaft suit, suitable for higher speeds and heavy loads plus an economical cost, make this the favorite choice for new styles 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 plain bore (pilot bore) and some share completed 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 established screws and a keyway. Clearance fits are well-known for light loads and slower speeds. A press suit (or shrink fit to the shaft) is normally favored for higher speeds or heavier loads because they suit to the shaft more safely than a clearance suit sprocket. Depending on the clearance of the shaft suit, sprockets may work slightly on the shaft causing feasible fretting or shaft use. All standard hub sprockets can be found with hardened the teeth from stock or on request. Press fits usually need the sprocket to end up being heated for set up to increase the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A set screw secures the main element. The TL Taper Bushed Sprocket will function 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 sprockets immediate mounting to the clients’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and 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 aswell. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, especially huge diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other standard drive components. 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 modern answer for upgrading clearance fit and press fit sprockets. TL Bushings are used in a wide variety of various other European and American regular drive products. STAINLESS Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion 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 tooth. Larger sizes available on ask for. TL Bushed version also on request. Metric Idler and Double-Single Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally provide tension for the chain drive and can be used within a pressure arm assembly or individually mounted to position the drive. Share 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 regulate pairs of rolls or drive units that must index. Customized Metric or ANSI Sprockets Custom sprockets including huge diameter metal or cast iron devices for single, duplex or triple strand chain can be made to order. PTI typically retains some stock in our European warehouse, therefore delivery could be rather quick. Additional custom made sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are favored to insure requirements are obvious. All are possible with customized finished bore.
