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, 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 support various application speeds. The more popular sizes are stocked with hardened teeth. The C45 materials, standard steel sprockets, permits induction hardening of teeth. So all can be high temperature treated Hardened Teeth on ask for. The TL Taper Bushed Sprocket offers a true 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 necessary for set up or removal. After the bushing installation screws are loosened and taken out, 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 inch bore TL bushings, a typical global design, which explains why the TL sprocket is indeed versatile. Ease of installation, concentric shaft suit, suitable for higher speeds and weighty loads plus a cost-effective price, make this the popular choice for new styles and replacement requirements. TL sprockets are generally 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) plus some stock finished bore sizes. Any shaft size can be done with our custom bore and keyway ability. Sprockets with hubs are typically 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 gradual speeds. A press fit (or shrink fit to the shaft) is generally preferred for higher speeds or heavier loads as they match to the shaft more securely than a clearance suit sprocket. With respect to the clearance of the shaft fit, sprockets may work slightly on the shaft causing feasible fretting or shaft wear. All regular hub sprockets are available with hardened tooth from stock or on ask for. Press fits usually need the sprocket to end up being 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 simpler to install. Plate Type Metric Sprockets Plate Sprockets for one, dual or triple strand chain are an economical choice allowing for immediate mounting to the customers’ hub or shaft. They are most frequently considered for sprockets above 40 teeth and are available in a wide variety of diameters. Plate type sprockets can be welded or bolted right to the users’ hub keeping products compact and light weight. They are available in single, double and triple tooth configurations as well. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, 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 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 ideal for replacements and a modern solution for upgrading clearance suit and press suit sprockets. TL Bushings are used in a wide variety of other European and American standard drive products. Stainless Steel Metric Sprockets Stainless Steel (AISI 304L) Metric Sprockets provide corrosion level of resistance and allow wash-down capability. These hub type sprockets could be given 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 teeth. Larger sizes available on demand. 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 stress for the chain drive and can be used 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, popular on conveyors, allow 2 single chains about the same sprocket to control pairs of rolls or drive devices that must index. Custom Metric or ANSI Sprockets Custom sprockets including large diameter metal or cast iron units for single, duplex or triple strand chain can be made to order. PTI typically will keep some stock in our European warehouse, therefore delivery could be rather quick. Other custom made sprockets sizes for Metric conveyor chain or ANSI chain are also possible. Drawings are preferred to insure requirements are obvious. All are possible with custom finished bore.
