The L190 coupling half with a 1-7/8" bore with a key-way is also commonly called an L190 coupling hub. The compact yet robust design of this 1-7/8" bore L190 coupling half makes it highly versatile across a broad spectrum of applications, including; pumps, blowers, compressors, mixers, motion control (servo), and more!. Depending on the insert type used, a complete L190 coupling assembly is capable of optimal operation with an angular misalignment from 0.5 to 1.0 degrees and a parallel misalignment of 0.10" to 0.15". This advantage is due to the greater radial softness. Additionally, L190 couplings utilize a no metal-on-metal design (excluding bronze inserts), drastically improving their wear life compared to other coupling types. At USA Roller Chain, we pride ourselves in supplying high-quality industrial power transmission components, and our L190 coupling halves with a 1-7/8" bore and key are no exception.
