Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide selection of sizes including 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 selection of diameters to support various app speeds. The more popular sizes are stocked with hardened the teeth. The C45 materials, standard steel sprockets, allows for induction hardening of teeth. So all can be high temperature treated Hardened Tooth on demand. The TL Taper Bushed Sprocket offers a true concentric suit to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft securely. Standard hex wrenches are the only tool necessary for installation or removal. Once the bushing installation screws are loosened and taken out, the screw is re-used and threaded in to the bushing removal hole. Tightening the removal screw will lightly loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a typical global design, which explains why the TL sprocket is so versatile. Simple installation, concentric shaft fit, ideal for higher speeds and large loads plus an economical price, make this the popular choice for new designs and replacement needs. TL sprockets are generally less expensive than customized or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum basic bore (pilot bore) and some share completed bore sizes. Any shaft size is possible with our custom made bore and keyway ability. Sprockets with hubs are usually fitted to the shaft as a clearance suit. They are held set up with two arranged screws and a keyway. Clearance fits are popular for light loads and slower speeds. A press suit (or shrink suit to the shaft) is generally preferred for higher speeds or heavier loads as they match to the shaft more securely than a clearance match sprocket. With respect to the clearance of the shaft fit, sprockets may work slightly on the shaft leading to possible fretting or shaft wear. All standard hub sprockets are available with hardened tooth from stock or on demand. Press fits usually require 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 established screw secures the key. 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 clients’ hub or shaft. They are most regularly regarded for sprockets above 40 teeth and are available in an array of diameters. Plate type sprockets can be welded or bolted right 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 mounting, especially huge diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as perform most of the other regular 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 alternative for upgrading clearance match and press fit sprockets. TL Bushings are found in a multitude of additional European and American regular drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down ability. These hub type sprockets can be provided with 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 teeth. Larger sizes available on ask for. TL Bushed edition 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 provide pressure 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, popular on conveyors, allow 2 single chains about the same sprocket to regulate pairs of rolls or drive devices that must index. Customized Metric or ANSI Sprockets Custom made sprockets including huge diameter metal or cast iron models for single, duplex or triple strand chain could be made to purchase. PTI typically maintains some stock inside our European warehouse, so delivery could possibly be rather quick. Other customized 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.
