The TB Wood’s line of L-Jaw couplings has recently been expanded to include a larger range of bore sizes, as well as new aluminum and stainless steel hubs. 
TB Wood’s jaw couplings are part-for-part interchangeable with industry-standard designs.
Jaw-type elastomeric couplings are an economical, proven solution for general purpose applications. TB Wood’s L-Jaw couplings are easy to install and require no lubrication or maintenance, while providing good vibration isolation and chemical resistance.
TB Wood’s L-Jaw couplings are an excellent choice for a wide range of light- and medium- duty industrial applications including fans, blowers, pumps, compressors, agitators and conveyors. Units feature a fail-safe design that allows equipment to continue to drive if the elastomer fails.
