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 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 an array of diameters to accommodate various application speeds. The popular sizes are stocked with hardened teeth. The C45 material, standard steel sprockets, permits induction hardening of teeth. So all could be temperature treated Hardened Tooth on demand. The TL Taper Bushed Sprocket offers 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 necessary for set up or removal. Once the bushing installation screws are loosened and removed, the screw is definitely re-used and threaded in to the bushing removal hole. Tightening the removal screw will carefully loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a standard global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft match, suitable for higher speeds and large loads plus an economical price, make this the favorite choice for new styles and replacement needs. TL sprockets are generally less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum plain bore (pilot bore) plus some share finished bore sizes. Any shaft size is possible with our customized bore and keyway capability. Sprockets with hubs are typically suited 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 suit to the shaft) is normally preferred for higher speeds or heavier loads as they match to the shaft more securely than a clearance fit sprocket. According to the clearance of the shaft fit, sprockets may work slightly on the shaft causing feasible fretting or shaft put on. All regular hub sprockets are available with hardened the teeth from share or on ask for. Press fits usually need the sprocket to be heated for installation to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A established screw secures the key. The TL Taper Bushed Sprocket will function like the press suit sprocket and generally simpler to install. Plate Type Metric Sprockets Plate Sprockets for solitary, dual or triple strand chain are a cost-effective choice allowing for direct mounting to the clients’ hub or shaft. They are most frequently regarded as for sprockets above 40 teeth and so are available in an array of diameters. Plate type sprockets could be welded or bolted directly to the users’ hub keeping gear 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 huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do many of the other regular 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 modern option for upgrading clearance suit and press suit sprockets. TL Bushings are used in a multitude of other European and American standard drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capacity. 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 the teeth. Larger sizes available on demand. TL Bushed edition also on demand. Metric Idler and Double-Solitary 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. Share sizes are for sale to ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known on conveyors, allow 2 single chains on a single sprocket to regulate pairs of rolls or drive devices that must index. 
Custom Metric or ANSI Sprockets Custom sprockets including huge diameter metal or cast iron models for solitary, duplex or triple strand chain can be made to purchase. PTI typically continues some stock inside 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. Each is possible with customized finished bore.
