It is important to determine proper torque tensioning preload rates for different bolts and materials. Figuring it out can be difficult, but there are standards used across the industrial spectrum. Read more

Plain Bearings (Bushings) are mechanical elements used to reduce friction between rotating shafts and stationary support members. Typically, a bushing relies on soft metal or plastic and an oil film to support the rotating shaft on the hardened shaft journal. Read more

Shaft Couplings are mechanical devices used to connect rotating shafts and absorb misalignments between them. Couplings can be rigid or flexible depending on the alignment accuracies of the system and torque requirements. Read more

Clamps are mechanical devices designed for the purpose of holding one item from moving relative to another. There are several variations of clamps with various functions. Read more
