Metric Sprockets

Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide selection of sizes which includes 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 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide variety of diameters to accommodate sprockets various program speeds. The popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of the teeth. So all can be heat treated Hardened Tooth on request. The TL Taper Bushed Sprocket provides a accurate concentric match 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. 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 indeed versatile. Simple installation, concentric shaft fit, suitable for higher speeds and heavy loads plus an economical cost, make this the popular choice for new styles and replacement needs. TL sprockets are usually less expensive than custom or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets are available with a minimum plain bore (pilot bore) and some stock completed bore sizes. Any shaft size is possible with our custom made bore and keyway ability. Sprockets with hubs are typically fitted to the shaft as a clearance match. They are held in place with two set screws and a keyway. Clearance fits are popular for light loads and slower speeds. A press fit (or shrink fit to the shaft) is usually favored for higher speeds or heavier loads as they suit to the shaft more safely than a clearance fit sprocket. With respect to the clearance of the shaft fit, sprockets may work somewhat on the shaft causing feasible 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 broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A set screw secures the key. The TL Taper Bushed Sprocket will function just like the press suit sprocket and generally easier 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 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 can be welded or bolted right to the users’ hub keeping tools compact and light-weight. They can be purchased in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify installation, especially large diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as perform most of the other standard drive elements. 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 modern remedy for upgrading clearance match and press suit sprockets. TL Bushings are used in a wide variety of various other European and American regular drive products. Stainless Steel Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion resistance and allow wash-down capability. These hub type sprockets could 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 on request. TL Bushed version also on demand. Metric Idler and Double-Solitary Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for installation. These sprockets generally provide stress for the chain drive and can be utilized within a tension arm assembly or separately mounted to position 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 on a single sprocket to regulate pairs of rolls or drive units that must index. Customized Metric or ANSI Sprockets Custom sprockets including huge diameter steel or cast iron systems for single, duplex or triple strand chain could be made to order. PTI typically keeps some stock in our European warehouse, so delivery could possibly be rather quick. Various other custom made sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are favored to insure requirements are clear. Each is possible with customized finished bore.
