Metric Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety 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 install with standard TL tapered bushings from 1008 thru 5050 (we.e., thru a 5” or 125mm shaft diameter). TL Sprockets can be found in a wide variety of diameters to accommodate various program speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of tooth. So all can be heat treated Hardened The teeth on ask for. The TL Taper Bushed Sprocket offers a true concentric fit 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 mounting screws are loosened and eliminated, the screw is usually re-used and threaded in to the bushing removal hole. Tightening the removal screw will lightly loosen the sprocket. PTI stocks both metric and ” 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 weighty loads plus a cost-effective price, make this the popular choice for new designs and replacement needs. TL sprockets are usually less expensive than custom or finished bored sprockets. Hub Type Metric Sprockets Hub Type Metric Sprockets can be found with a minimum plain bore (pilot bore) and some share finished bore sizes. Any shaft size can be done with our customized bore and keyway ability. Sprockets with hubs are usually fitted to the shaft as a clearance fit. They are held in place with two established screws and a keyway. Clearance fits are popular for light loads and slow speeds. A press match (or shrink match to the shaft) is generally favored for higher speeds or heavier loads because they fit to the shaft more securely than a clearance suit sprocket. Based on the clearance of the shaft match, sprockets may work somewhat on the shaft causing feasible fretting or shaft use. All standard hub sprockets are available with hardened the teeth from stock or on request. Press fits usually need 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 arranged 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 solitary, dual 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 are available in a wide selection 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 often used to simplify mounting, especially large sprockets diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do many of the other standard 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 well suited for replacements and a modern solution for upgrading clearance match and press match sprockets. TL Bushings are found in a wide variety of additional European and American regular drive products. STAINLESS Metric Sprockets STAINLESS (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capacity. These hub type sprockets can be given a finished 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 the teeth. Larger sizes on request. TL Bushed edition 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 used within a pressure 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, popular on conveyors, allow 2 single chains about the same sprocket to control pairs of rolls or drive products that must index. Custom Metric or ANSI Sprockets Custom made sprockets including huge diameter metal or cast iron models for one, duplex or triple strand chain can be made to order. PTI typically maintains some stock in our European warehouse, so delivery could be rather quick. Various other custom sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are clear. Each is possible with customized finished bore.
