Metric Sprockets

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, dual and triple chain. These install with sprockets regular TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in a wide selection of diameters to accommodate various program speeds. The popular sizes are stocked with hardened tooth. The C45 material, standard steel sprockets, allows for induction hardening of teeth. So all can be warmth treated Hardened The teeth on demand. The TL Taper Bushed Sprocket offers a accurate concentric suit 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 installation or removal. Once the bushing installation screws are loosened and taken out, the screw can be re-used and threaded into the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a typical global design, which is why the TL sprocket is so versatile. Ease of installation, concentric shaft match, suitable for higher speeds and heavy loads plus an economical price, make this the popular choice for new styles and replacement requirements. 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 plain bore (pilot bore) plus some stock finished bore sizes. Any shaft size is possible with our customized 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 well-known for light loads and slow speeds. A press match (or shrink suit to the shaft) is generally favored for higher speeds or heavier loads as they fit to the shaft more safely than a clearance suit sprocket. Based on the clearance of the shaft suit, sprockets may work somewhat on the shaft leading to feasible fretting or shaft put on. All regular hub sprockets can be found with hardened tooth from share or on request. Press fits usually require the sprocket to be heated for set up to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A arranged screw secures the main element. The TL Taper Bushed Sprocket will function just 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 direct mounting to the customers’ hub or shaft. They are most regularly regarded as for sprockets above 40 teeth and are available in an array of diameters. Plate type sprockets could be welded or bolted directly to the users’ hub keeping tools compact and light weight. They are available in single, dual and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other standard 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 contemporary alternative for upgrading clearance match and press suit sprockets. TL Bushings are found in a multitude of other European and American standard drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capability. 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 request. TL Bushed version 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 utilized within a pressure arm assembly or individually mounted to put the drive. Share sizes are available for 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 products that must index. Custom Metric or ANSI Sprockets Custom made sprockets including large diameter steel or cast iron units for one, 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 possible. Drawings are preferred to insure requirements are obvious. All are possible with custom finished bore.
