RM Type Couplings are rigid couplings that are primarily used to rigidly connect the ends of two shafts. The product range includes a wide range of sizes and types to suit different market needs. This coupling is particularly suitable for use in any shaft connection where precise alignment is required but flexibility is not required.
In addition, RM Type Couplings need to be dynamically balanced to the extent of Q6.3 when the rotational speed reaches half of its limit.
In summary, RM Type Couplings are an efficient solution designed for rigid shaft connections, available in a wide range of sizes and types to meet the needs of different markets, with excellent mechanical properties and durability.
