March 1, 2009 - Rexroth announced MKK hygienic modules and the MKK and MKR 12-40 miniature linear modules. MKR hygienic modules are ideal for food processing machinery and other food or packaging applications. The MKK and MKR 12-40 miniature modules have the smallest and most compact aluminum profile in the series, allowing them to solve new applications where size is a factor and performance can not be sacrificed.The new MKR hygienic option has a specially-designed aluminum profile that is smoother than standard MKR bodies to prevent build-up of liquids and foreign debris.
Combined with the MKR’s proven stainless steel strip cover for the drive and guide elements, the new design allows the MKR to eliminate residual liquid in applications such as food processing machines or other washdown environments.These new hygienic modules are precise, high-performance linear systems with compact dimensions in a ready-to-mount design. With lengths up to 12 meters and speeds to 5 m/s, the belt-driven MKR hygienic modules use precision Rexroth Ball Rail® systems for internal guidance to achieve precise positioning. For additional protection against contamination, thin dense chrome plating can be applied to many internal components.
Standard peripherals include add-on parts for Rexroth servo motors, suitable regulators, and controls.The new MKK and MKR 12-40 miniature linear module option offers big performance in a small footprint to meet demanding speed and load requirements. The modules feature a rigid aluminum frame, and can be specified in either a belt-driven version for precise positioning and zero backlash, or a ballscrew-driven version to achieve travel speeds of up to 3 m/s.MKK and MKR 12-40 miniature modules boast an excellent price-to-performance ratio and are well-suited to applications in the food and packaging, medical, material handling, semiconductor and automotive industries. They are ideal for gantry-style applications, pick-and-place, loading/unloading, assembly, positioning and inspection tasks.
The miniature modules have a single-point lubrication design that reduces maintenance time and cost, and lengths can be specified from 250mm to 2,500mm depending on the drive.
