KSK Model

Product catalog summary

Overview: The document provides detailed information about Oldham Couplings, specifically the KSK series, which are designed for high torsional stiffness and are backlash-free. These couplings are ideal for applications where space is limited and precision is required, such as in servo and positioning drives.

Specifications: The KSK couplings are made from an aluminum alloy with a polyacetal intermediate piece, offering easy mounting and removal. They operate within a temperature range of -30°C to 80°C and are suitable for use with servomotors and stepper motors. The maximum rated torque is 7 N·m, with bore ranges from 3 mm to 16 mm.

Applications: These couplings are used in positioning systems, conveyors, spindle drives, actuator drives, linear drives, and distributed drives, providing high stiffness, low inertia, and long service life.

Models and Dimensions: The document lists various models such as KSK 2 AA, KSK 3 AA, and KSK 4 AA, each with specific rated torque, misalignment capabilities, maximum rotation speed, torsional stiffness, moment of inertia, and mass. Dimensions for each model are provided, including bore diameters and tightening torque of screws.

Ordering Information: The document outlines how to place an order, specifying the model, size, type (AA: Set screw, BB: Clamping hub, BC: Expanding shaft), and bore diameter (d1/d2).

This three-part plug-in coupling grew out of an idea to develop a backlash-free Oldham coupling. It is now an indispensable part of all servo and positioning drives. The KSK, which offers precision, a lightweight design and a high level of torsional stiffness, offers an alternative solution to elastomer couplings in the case of high-precision systems.
