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, double and triple chain. These attach with standard TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in an array of diameters to support various program speeds. The popular sizes are stocked with hardened teeth. The C45 material, standard steel sprockets, allows for induction hardening of the teeth. So all could be temperature treated Hardened The teeth on ask for. 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 securely. Standard hex wrenches will be the only tool required for installation or removal. After the bushing installation screws are loosened and removed, the screw can be re-used and threaded into the bushing removal hole. Tightening the removal screw will lightly 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 match, ideal for higher speeds and weighty loads plus an economical price, make this the favorite choice for new designs and replacement requirements. TL sprockets are generally less expensive than customized or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum ordinary bore (pilot bore) and some share completed bore sizes. Any shaft size is possible with our custom bore and keyway sprockets capacity. Sprockets with hubs are usually fitted to the shaft as a clearance match. They are held in place with two established screws and a keyway. Clearance fits are well-known for light loads and slower speeds. A press suit (or shrink suit to the shaft) is generally 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 put on. All standard hub sprockets are available with hardened the teeth from share or on demand. Press fits usually need the sprocket to become heated for set up 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 just like the press fit sprocket and generally easier to install. Plate Type Metric Sprockets Plate Sprockets for solitary, dual or triple strand chain are an economical choice allowing for immediate mounting to the customers’ 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 right to the users’ hub keeping apparatus compact and light weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, 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 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 perfect for replacements and a contemporary solution for upgrading clearance match and press suit sprockets. TL Bushings are used in a wide variety of other European and American standard 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 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 the teeth. Larger sizes on request. TL Bushed edition 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 utilized within a tension arm assembly or individually mounted to put the drive. Stock sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, popular 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 Customized sprockets including huge diameter steel or cast iron products for single, duplex or triple strand chain could be made to purchase. PTI typically maintains some stock in our European warehouse, so delivery could possibly be rather quick. Other custom 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.
