The Lamaflex disc coupling is an all-steel torsionally rigid coupling ideal to connect pumps, compressors, electric motors and other type of machinery.
This is a flexible disc style coupling used to link machine shafts and compensate little shaft misalignments while generating low restorative forces. The flexibility of these couplings is obtained from the flexing of thin metallic discs. The disc packs, composed of these individual thin plates held together by a socket and a ring, able to expand slightly when there is a misalignment, absorbing the vibrations and shock loads coming from the driver side.

This coupling is available with two alternative configurations.
The KL configuration, composed of two hubs and one-disc pack kit, and the FLS and KLS types, composed by two hubs, a spacer, and two-disc pack kits. Both configurations can accommodate axial and angular misalignments, but only the FLS and KLS alternatives (the spacer accommodate radial misalignment owing to have two flexible disc packs.
The disc packs are manufactured using high grade stainless steel (AISI-301), ensuring high strength and high endurance to fatigue as well as resistance to most environmental conditions. Lamaflex disc couplings utilizes unitised disc packs with 4 or 6 bolting points designs. The higher bolting points in each disc pack, the larger the torque is able to transmit. However, smaller are the misalignments the coupling can accommodate.
Features and benefits of disc couplings
- Zero maintenance: No routine maintenance or lubrication required
- No backlash: The torsionally stiff design ensures there is zero backlash, making ideal when constant speed is crucial
- Low operating cost: Easy installation and replacement, allowing inspection without disassemble Long life-cycle: Infinite life if assembled and aligned correctly
- Practical use: Single disc and double disc pack configurations available and it operates in either directions
- Misalignment capabilities: Compensates angular, axial and radial misalignments
- High power rating per size of coupling
- Lightweight components: One of the lowest bearing loads available in a motion control coupling
- Resistant to harsh environments
- Working temperature range from -40 °C to +280 °C
Application fields
- Where high torque is required.
- Without strong vibrations and with slight misalignments.
- Ideal for applications where not much space is available.
- Resistant to high temperature environments.
