Metric chain sprocket Sprockets Overview
TL Taper Bushed Metric Sprockets
TL Sprockets are stocked in a wide variety 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 attach with regular 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 accommodate various app speeds. The popular sizes are stocked with hardened the teeth. The C45 materials, standard steel sprockets, allows for induction hardening of teeth. So all can be heat treated Hardened Teeth on demand. The TL Taper Bushed Sprocket provides a true 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. After 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 lightly loosen the sprocket. PTI stocks both metric and ” bore TL bushings, a typical global design, which explains why the TL sprocket is so versatile. Ease of installation, concentric shaft suit, ideal for higher speeds and weighty loads plus a cost-effective cost, make this the popular choice for new styles and replacement requirements. 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 simple bore (pilot bore) and some share finished bore sizes. Any shaft size is possible with our customized bore and keyway capacity. Sprockets with hubs are usually suited to the shaft as a clearance match. They are held in place with two arranged screws and a keyway. Clearance fits are popular for light loads and gradual speeds. A press match (or shrink match to the shaft) is usually favored for higher speeds or heavier loads because they suit to the shaft more safely than a clearance match sprocket. With respect to the clearance of the shaft fit, sprockets may work slightly on the shaft leading to feasible fretting or shaft wear. 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 increase the bore. As a heated sprocket cools, it shrinks, conforming to the shaft with a tight grip. A established screw secures the key. The
