Metric Sprockets

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 attach with regular 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 program 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 could 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 will be the only tool required for installation or removal. After the bushing mounting screws are loosened and eliminated, the screw is certainly re-used and threaded into the bushing removal hole. Tightening the removal screw will carefully loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a typical global design, which explains why the TL sprocket is indeed versatile. Simple installation, concentric shaft match, 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 completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum plain bore (pilot bore) and some share finished bore sizes. Any shaft size is possible with our custom bore and keyway capacity. Sprockets with hubs are chain sprocket typically fitted to the shaft as a clearance match. They are held in place with two set screws and a keyway. Clearance fits are well-known for light loads and gradual speeds. A press suit (or shrink suit to the shaft) is normally favored for higher speeds or heavier loads because they fit to the shaft more safely than a clearance match sprocket. With respect to the clearance of the shaft suit, sprockets may work somewhat on the shaft leading to possible fretting or shaft use. All standard hub sprockets are available with hardened teeth from share or on request. Press fits usually require the sprocket to end up being heated for installation 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 suit sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for solitary, dual or triple strand chain are a cost-effective choice allowing for immediate mounting to the clients’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and so are available in a wide selection of diameters. Plate type sprockets could be welded or bolted directly to the users’ hub keeping equipment compact and light-weight. They can be purchased in single, double and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially huge diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform most of the other regular drive elements. 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 perfect for replacements and a modern answer for upgrading clearance suit and press match sprockets. TL Bushings are used in a wide variety of other European and American standard drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capacity. These hub type sprockets can be given 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 teeth. Larger sizes available on request. TL Bushed version also on ask for. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. 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. 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 products that must index. Custom Metric or ANSI Sprockets Custom made sprockets including huge diameter steel or cast iron systems for single, duplex or triple strand chain could be made to order. PTI typically will keep some stock in our European warehouse, so delivery could 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.
