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, double and triple chain. These install 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 support various software speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of teeth. So all could be high temperature treated Hardened Teeth on demand. 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 will be the only tool required for set up or removal. Once the bushing installation screws are loosened and removed, the screw can be re-used and threaded in to the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a standard global design, which explains why the TL sprocket is indeed versatile. Simple installation, concentric shaft suit, 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 customized or completed bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum plain bore (pilot bore) plus some stock completed bore sizes. Any shaft size can be done with our customized bore and keyway capability. Sprockets with hubs are usually suited to the shaft as a clearance suit. 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 fit (or shrink suit to the shaft) is usually preferred for higher speeds or heavier loads because they match to the shaft more safely than a clearance match sprocket. According to the clearance of the shaft fit, sprockets may work somewhat on the shaft leading to feasible fretting or shaft use. All regular hub sprockets are available with hardened the teeth from stock or on ask for. Press fits usually require the sprocket to become 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 match 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 frequently regarded for sprockets above 40 teeth and are available in a wide range of diameters. Plate type sprockets can be welded or bolted directly to the users’ hub keeping devices compact and light-weight. They can be purchased in single, double and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is frequently used to simplify installation, especially large diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the typical TL bushings as do most of the other regular drive components. 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 alternative for upgrading clearance suit and press fit sprockets. TL Bushings are used in a multitude of other 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 can be given 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 the teeth. Larger sizes available on demand. TL Bushed version also on demand. Metric Idler and Double-Single Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally offer tension for the chain drive and can be utilized within a pressure arm assembly or individually mounted to put the drive. Share 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 regulate pairs of rolls or drive systems that must index. Customized Metric or ANSI Sprockets Customized sprockets including large diameter steel or cast iron devices for solitary, duplex or triple strand chain could be made to purchase. PTI typically maintains some stock in our European warehouse, so delivery could 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 obvious. Each is possible with customized finished bore.
