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 regular TL tapered bushings from 1008 thru 5050 (i.e., thru a 5” or 125mm shaft diameter). TL Sprockets are available in a wide variety of diameters to support various program speeds. The more popular sizes are stocked with hardened the teeth. The C45 material, standard steel sprockets, allows for induction hardening of the teeth. So all can be warmth treated Hardened The teeth on ask for. The TL Taper Bushed Sprocket provides a accurate concentric suit 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 required for installation or removal. After the bushing mounting screws are loosened and removed, the screw is definitely re-used and threaded into the bushing removal hole. Tightening the removal screw will lightly loosen the sprocket. PTI stocks both metric and inch bore TL bushings, a standard global design, which explains why the TL sprocket is so versatile. Simple installation, concentric shaft match, ideal for higher speeds and large loads plus an economical 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 are available with a minimum ordinary bore (pilot bore) and some stock finished bore sizes. Any shaft size can be done with our custom made bore and keyway ability. Sprockets with hubs are typically fitted to the shaft as a clearance fit. 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 suit (or shrink suit to the shaft) is generally preferred for higher speeds or heavier loads because they fit to the shaft more securely than a clearance match sprocket. With respect to the clearance of the shaft suit, sprockets may work somewhat on the shaft leading to possible fretting or shaft put on. All standard hub sprockets are available with hardened the teeth from share or on request. Press fits usually need the sprocket to end up being heated for installation to broaden the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a good grip. A established 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, dual or triple strand chain are an economical choice allowing for immediate mounting to the customers’ hub or shaft. They are most regularly considered for sprockets above 40 teeth and so are available in a wide selection of diameters. Plate type sprockets could 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 as well. Weld on Hubs A Weld-On-Hub is often used to simplify mounting, especially huge diameter sprockets. PTI stocks regular TL Weld-OnHub sizes. The Weld-On-Hub uses the standard TL bushings as do many of the other regular drive elements. TL Bushings are stocked in both metric and inch 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 match and press match sprockets. TL Bushings are used in a multitude of various other 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 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 teeth. Larger sizes on demand. TL Bushed edition also on request. Metric Idler and Double-One Sprockets Metric Idler Sprockets are plate sprockets with a ball bearing for mounting. These sprockets generally provide tension for the chain drive and can be utilized within a tension arm assembly or individually mounted to put the drive. Stock sizes are available for ISO 05B thru 20B metric chain sizes. Double-Single Sprockets, well-known on conveyors, allow 2 single chains about the same sprocket to regulate pairs of rolls or drive products that must index. Custom Metric or ANSI Sprockets Customized sprockets including huge diameter steel or cast iron devices for single, duplex or triple strand chain could be made to purchase. PTI typically maintains some stock inside our European warehouse, therefore delivery could possibly be rather quick. Other custom sprockets sizes for Metric conveyor chain or ANSI chain are also feasible. Drawings are preferred to insure requirements are clear. Each is possible with custom finished bore.
