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 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 variety of diameters to accommodate various app speeds. The more popular sizes are stocked with hardened tooth. The C45 material, standard steel sprockets, permits induction hardening of tooth. So all can be warmth treated Hardened Tooth on request. The TL Taper Bushed Sprocket provides a true concentric suit to the shaft. As the TL bushing screws are tightened, the bushing compresses around the shaft securely. Standard hex wrenches will be the only tool required for installation or removal. After the bushing mounting screws are loosened and taken out, the screw is re-used and threaded in to the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a standard global design, which explains why the TL sprocket is so versatile. Simple installation, concentric shaft fit, ideal for higher speeds and large loads plus a cost-effective cost, make this the popular choice for new designs and replacement requirements. TL sprockets are usually less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum basic bore (pilot bore) plus some stock completed bore sizes. Any shaft size is possible with our custom made bore and keyway capacity. Sprockets with hubs are typically suited to the shaft as a clearance match. They are held set up with two arranged screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press match (or shrink suit to the shaft) is usually preferred for higher speeds or heavier loads as they match to the shaft more safely 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 put on. All regular hub sprockets are available with hardened tooth from share or on demand. Press fits usually require the sprocket to become heated for installation to expand the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A set screw secures the key. The TL Taper Bushed Sprocket will function just like the press fit 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 clients’ hub or shaft. They are most frequently regarded 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 apparatus compact and light-weight. They are available in single, double and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially large diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform many of the other regular drive components. TL Bushings are stocked in both metric and inch 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 ideal for replacements and a contemporary option for upgrading clearance suit and press suit sprockets. TL Bushings are found in a multitude of additional European and American regular drive products. STAINLESS Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down ability. These hub type sprockets could 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 on ask for. TL Bushed version also on demand. Metric Idler and Double-One 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 tension arm assembly or separately mounted to put the drive. Stock sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known on conveyors, allow 2 single chains on a single sprocket to control pairs of rolls or drive systems that must index. Custom Metric or ANSI Sprockets Custom made sprockets including large diameter metal or cast iron units for one, duplex or triple strand chain could be made to purchase. PTI typically keeps some stock inside our European warehouse, so delivery could possibly be rather quick. Other custom 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.
