For chain drives that need dependable power transmission, SKF offers the PHS series with TBH suffix. These sprockets are made from high-quality steel and heat treated to resist wear. They appear in gearboxes, conveyors, agricultural machinery and other industrial equipment. MR Industrial Accessories supplies this line and can help you match the right pitch and tooth count to your application.
The part number tells you the key specifications. Take PHS 40-1TBH14: pitch 40 (1/2 inch), single strand, 14 teeth. PHS 40-2TBH18 means pitch 40, double strand, 18 teeth. The TBH suffix indicates the hub and mounting style. Reading these details correctly is essential for a trouble-free replacement.
You will find these sprockets in chain drives on industrial machines, conveyors, elevators, and equipment for food processing, woodworking and agriculture. Their sturdy build handles demanding conditions and offers good resistance to fatigue and wear.
When selecting a sprocket, confirm the chain pitch, the number of teeth and the shaft diameter. Correct alignment and proper chain tension are critical. Lubrication and sealing that keep contaminants out will extend the life of the assembly. For high-load drives, a sprocket with more teeth can help reduce wear.
SKF sprockets can be interchanged with other brands that use the same pitch and dimensional standards. Before replacing, always check hub dimensions, outer diameter and bore. Interchangeability depends on standardized tolerances being met. If you are unsure, our technical team can assist.
