Metric sprockets 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 an array of diameters to accommodate various software speeds. The popular sizes are stocked with hardened tooth. The C45 materials, standard steel sprockets, permits induction hardening of the teeth. So all could be warmth treated Hardened Teeth on demand. The TL Taper Bushed Sprocket offers a accurate concentric match 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 necessary for set up or removal. After the bushing mounting screws are loosened and removed, the screw is certainly re-used and threaded in to the bushing removal hole. Tightening the removal screw will softly loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a standard global design, which explains why the TL sprocket is so versatile. Ease of installation, concentric shaft fit, ideal for higher speeds and weighty 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 can be found with a minimum basic bore (pilot bore) and some share completed bore sizes. Any shaft size is possible with our custom made bore and keyway capacity. Sprockets with hubs are usually suited to the shaft as a clearance fit. They are held in place with two arranged screws and a keyway. Clearance fits are well-known for light loads and slow speeds. A press match (or shrink fit to the shaft) is generally preferred for higher speeds or heavier loads as they suit to the shaft more safely than a clearance match sprocket. Based on the clearance of the shaft suit, sprockets may work somewhat on the shaft causing feasible fretting or shaft wear. All standard hub sprockets are available with hardened teeth from stock or on ask for. Press fits usually require the sprocket to be heated for installation to increase the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A established 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 clients’ hub or shaft. They are most regularly 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 products compact and light weight. They can be purchased in single, dual and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is frequently used to simplify mounting, 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 parts. TL Bushings are stocked in both metric and ” 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 option for upgrading clearance suit and press match sprockets. TL Bushings are used in a multitude 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 available 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 mounting. These sprockets generally provide pressure for the chain drive and can be utilized within a stress 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, 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 Customized sprockets including huge diameter steel or cast iron systems for single, duplex or triple strand chain can be made to order. PTI typically maintains some stock inside our European warehouse, therefore delivery could possibly be rather quick. Additional custom made sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are clear. All are possible with customized finished bore.
