Distributor

Couplings

Bearings Specialist Co., Ltd. is an authorized distributor of Optibelt, Fenner, Regal Rexnord, Momentum, AYA, and Lovejoy, supplying a complete range of shaft couplings engineered for reliable and efficient power transmission.

Our product range covers a wide variety of coupling types, including rigid, chain, gear, grid, elastomeric, and disc couplings, as well as specialized cooling tower couplings. These solutions support a broad range of applications across manufacturing, processing, and general industries throughout Thailand.

Every product is sourced directly from our brand partners, ensuring customers receive genuine components with consistent quality, reliable performance, and engineering standards trusted across industrial applications.

Why Couplings Matter

Couplings connect two shafts to transmit torque while accommodating shaft misalignment, absorbing shock, and helping protect connected machinery from vibration and load spikes.

Selecting the right coupling type for your application directly affects drive efficiency, noise levels, and the service life of both the coupling and connected equipment. Using a mismatched or low-quality coupling can result in premature wear, vibration-related damage, and unplanned downtime.

Working with a trusted distributor that supplies genuine, correctly specified couplings helps protect your equipment investment, reduce operational risks, and maintain reliable power transmission performance over the long term.

Our Coupling Range

Rigid Couplings

Rigid couplings connect two shafts as a single solid unit without flexibility, requiring precise shaft alignment during installation.

They offer simple and cost-effective torque transmission, making them suitable for applications where the shafts are already accurately aligned and no misalignment compensation, vibration damping, or shock absorption is required.

Chain Couplings

Chain couplings connect two shafts using a double-strand roller chain wrapped around two matching hubs (sprockets), allowing them to transmit torque while accommodating minor shaft misalignment.

With a simple and practical design, chain couplings are easy to install, inspect, and replace, making them suitable for general industrial drive applications that require reliable performance and convenient maintenance.

Gear Couplings

Gear couplings use two hubs with external gear teeth that mesh with a common internally toothed sleeve, allowing them to transmit high torque while accommodating angular and axial shaft misalignment.

With a compact and high-strength design, gear couplings are well suited to heavy-duty industrial drive applications such as mills, pumps, and compressors.

Grid Couplings

Grid couplings use a flexible, serpentine-shaped steel grid that fits into slotted hubs on each shaft, providing reliable torque transmission while accommodating shaft misalignment and absorbing shock.

Their durable metal construction provides high torque capacity for heavy-duty industrial applications while offering better vibration absorption than fully rigid couplings.

Disc Couplings

Disc couplings use a series of thin metal discs to connect two shafts, transmitting torque through the disc pack while flexing to accommodate shaft misalignment without wearing or backlash-prone components.

Because they contain no elastomeric or lubricated components, disc couplings offer long service life and consistent performance, making them well suited to precision drive applications. We supply the Thomas disc coupling range, part of the Regal Rexnord family.

Elastomeric Couplings

Elastomeric couplings use a flexible rubber or polyurethane element between two metal hubs to transmit torque while absorbing shock, dampening vibration, and accommodating shaft misalignment.

Because the elastomeric element can be replaced without moving either connected machine, these couplings are valued for easy maintenance. Our elastomeric coupling range includes several established designs, each suited to different load, alignment, and maintenance requirements.

Flex Coupling

Flex couplings use a molded elastomeric insert fitted between two jaw-type hubs, providing easy installation and reliable torque transmission with moderate misalignment tolerance.

Their straightforward design makes them a cost-effective and widely used choice for general industrial drive applications.

Pex Coupling

Pex couplings are compact elastomeric couplings with a shorter overall length than standard flex couplings, making them suitable for applications where axial space is limited.

They provide reliable torque transmission and moderate shock absorption for general drive applications.

HRC Coupling

HRC (Highly Resilient Coupling) couplings use a highly flexible, tyre-shaped rubber element secured between two hubs, providing effective shock absorption, vibration dampening, and misalignment tolerance.

The rubber element can be replaced without disturbing the connected machinery, making HRC couplings suitable for both general and heavy industrial drive applications.

Wrapflex Coupling

Wrapflex couplings use a flexible elastomeric element that wraps around projecting pins on both hubs, allowing the element to be installed or removed radially without moving either connected shaft.

This design is particularly suitable for applications with limited installation space where axial movement of the machinery is impractical during maintenance.

Crownpin Coupling

Crownpin couplings use crowned, barrel-shaped pins fitted with elastomeric sleeves that engage with slotted hubs on each shaft. This design provides smooth torque transmission while accommodating misalignment and absorbing shock loads.

The coupling design also allows the flexible elements to be inspected and replaced conveniently.

Pin and Bush Coupling

Pin and bush couplings use metal pins fitted with rubber bushes that engage with holes in the opposing hub, providing a simple and durable method of torque transmission while absorbing shock and accommodating minor shaft misalignment.

Their robust construction makes them a reliable and cost-effective choice for general industrial machinery.

L-Type Coupling

L-Type (jaw) couplings use interlocking jaws on each hub with a spider-shaped elastomeric element positioned between them. They provide reliable torque transmission with good shock absorption and easy maintenance.

Widely recognized under brands such as Lovejoy, these couplings are commonly used with pumps, fans, and general industrial drive equipment.

Cooling Tower Coupling

Cooling tower couplings are specialized couplings designed for low-speed, high-torque applications, specifically for cooling tower fan drive shafts that operate continuously in wet, humid, and potentially corrosive environments.

We supply Addax cooling tower couplings, part of the Regal Rexnord family, engineered specifically for demanding applications requiring high durability and reliable performance.
