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 mount with standard TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in an array of diameters to support various app speeds. The more popular sizes are stocked with hardened the teeth. The C45 material, standard steel sprockets, permits induction hardening of teeth. So all can be heat treated Hardened Tooth 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 safely. Standard hex wrenches will be the only tool required for installation or removal. Once the bushing installation screws are loosened and taken out, the screw is certainly re-used and threaded into the bushing removal hole. Tightening the removal screw will gently loosen the sprocket. PTI stocks both metric and in . bore TL bushings, a typical global design, which explains why the TL sprocket is indeed versatile. Ease of installation, concentric shaft fit, suitable for higher speeds and weighty loads plus a cost-effective price, make this the favorite choice for new styles and replacement needs. TL sprockets are generally 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 share completed bore sizes. Any shaft size is possible with our custom made bore and keyway ability. Sprockets with hubs are typically suited 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 sluggish speeds. A press suit (or shrink suit to the shaft) is generally favored for higher speeds or heavier loads as they fit to the shaft more safely than a clearance fit sprocket. Based on the clearance of the shaft match, sprockets may work slightly on the shaft leading to possible fretting or shaft put on. All regular hub sprockets can be found with hardened tooth from stock or on demand. Press fits usually need the sprocket to be heated for set up to expand 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 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 direct mounting to the clients’ hub or shaft. They are most frequently regarded as for sprockets above 40 teeth and are available in an array 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, dual and triple tooth configurations aswell. Weld on Hubs A Weld-On-Hub is frequently used to simplify installation, especially huge diameter sprockets. PTI stocks standard TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do most of the other regular drive elements. 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 ideal for replacements and a modern answer for upgrading clearance fit and press suit sprockets. TL Bushings are found in a wide variety of various other European and American regular drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capacity. These hub type sprockets could be provided with a completed bore and keyway. Stainless Sprockets cannot be hardened. PTI stocks sizes from ISO 06B thru 16B (3/8” -1” pitch) and from 12 to 25 & 30 tooth. Larger sizes on ask for. TL Bushed edition also on ask for. 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 utilized within a tension arm assembly or individually mounted to put the drive. Share 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 control pairs of rolls or drive products that must index. Custom Metric or ANSI Sprockets Customized sprockets including large diameter steel or cast iron systems for one, duplex or triple strand chain can be made to order. PTI typically helps to keep some stock in our European warehouse, so delivery could possibly be rather quick. Additional custom sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are clear. All are possible with customized finished bore.
