Custom Designed Two-Piece Couplings Offer a Superior Solution for Line Shafts

Climax two-piece clamping couplings provide a superior solution for line shaft failed components, saving countless hours of downtime and increasing productivity.

Line shafts are an essential element in the power transmission industry and are used primarily to synchronize multiple components on equipment. Line shafts are common in many industries, including Timber, Forestry, Food Processing, Glass Production, Bottling, and Mills.

Recently, a customer was faced with a challenge where a one-piece tapered bushing used to mount several lever arms onto a line shaft continued to fail. As a result of using a one-piece tapered bushing, maintenance was tasked with the tedious process of removing all other components mounted between the bushing and the egress point. This removal process was often labor-intensive and required extended downtime, resulting in a loss of profits and productivity.


Large Bore Couplings Provide Solution for Line Shaft Timber Applications

Large Bore Coupling

Large Bore Couplings Popular for Sawmills:
Bore Sizes 1-15/16”, 2-7/16”, 2-15/16”, 3-7/16”, 3 15/16”, 4 7/16”

Climax large bore shaft couplings provide a higher strength alternative over antiquated traditional approaches in timbering applications while transmitting higher loads necessary for line shafts.

From initial harvesting to final product, machinery used in forestry (sawmill) applications is constantly subjected to some of the harshest environments and strenuous loads for which an engineer can design.

The true workhorse of the coupling family, rigid couplings can be used in many line shaft applications in the timber industry.

Climax’s state of the art facility, located in Mentor, Ohio, manufactures couplings with up to a 5” bore, with the capability to go larger depending on the application. Climax also offers (more…)

KLD Mechanical Interference Fit an Optimal Solution for Sawmill Systems & Planar/Feed Tables

Climax Keyless Locking Devices withstand the constant pounding associated with timber processing applications making them an ideal replacement for expensive and time consuming traditional interference fit connections.

Timber Sawmill ProcessSawmill Systems and Planer/Feed Tables commonly incorporate traditional keyed connections when attaching feed rollers in sawmill equipment. Using a keyed connection adds weight and cost not only to the shaft but to every component on the shaft. Over time, keyways cause fretting corrosion, allowing for backlash, and do not transmit bending moments or axial loads.

Climax Keyless Locking Assemblies can be used in place of a keyed connection removing these disadvantages especially when subjected to extreme environments where constant load reverses are common. Keyless locking devices use multiple screws with opposing tapers creating a 360° contact mechanical interference fit. Where pin retention is used in sawmill equipment, using a C133 or C405 locking assembly eliminates the need for (more…)

Hydraulic Motor & Conveyor Systems Benefit With the Use of Keyless Rigid Couplings

Climax Keyless Rigid Couplings provide a superior solution for shaft mounted hydraulic motors and gearboxes over traditional approaches in timber conveying applications.

KLD Hydraulic Motor Conveyor SystemsTraditional methods used to shaft mount hydraulic motors and/or gearboxes in conveyor application such as wood chippers; include the need for brackets and expensive structures to support the motor. Failure to properly align shafts in these applications can lead to premature coupling failure. Additionally, misalignment can lead to hydraulic motor leaks and total bearing failures due to inordinate facial loads on the motor bearings, resulting in maintenance issues and downtime consequently affecting production and profitability. Even when these components are properly aligned these connections are subjected to outside elements that can affect alignment.

Climax Series C600 Keyless Rigid Couplings provide the desired high torque and bending capacity required for conveyor applications thus eliminating bearing and motor failure. Shaft mounting the drive ensures that shafts are in perfect alignment, removing the chance of hydraulic motor leaks (more…)

Keyless Locking Devices Provide Superior Connection Solution for Wood Chippers

Climax Keyless Locking Devices withstand the constant pounding associated with wood processing applications making them an ideal replacement for expensive and time consuming traditional interference fit connections.

Timber Wood Chipper

Wood Chipper

Interference fit rotor/shaft connections common in wood chippers require expensive machining, fixturing, and the use of heavy hydraulic presses. As these traditional fits require close tolerances there is a great deal of labor involved to facilitate assembly.

Climax heavy duty locking assemblies can achieve the same fit with a much simpler and less expensive machining. Keyless locking assemblies are installed and removed with simple hand tools making them ideal for applications that require field serviceability. The same heavy duty locking assemblies can be used to mount drive sheaves on wood chippers eliminating wallowing, fretting corrosion, and fatigue failure, commonly associated with shaft keyways. The harsh demands of constant pounding in wood processing applications (more…)

KLDs Offer Superior Torsion & Bending Capability for Timber Industry Debarkers

Climax Keyless Locking Devices provide a superior alternative for component connectivity in timber applications where keyed connections commonly result in excessive downtime and loss of production.

Timber Log DebarkerDue to the harsh nature of the lumber and wood industry, sheared and rolled keys and broken shafts are common on equipment such as debarkers. Shaft/hub connections in this industry are subjected to a constant pounding which eventually leads to shaft fatigue failures of keyed connections resulting in downtime and loss of production.

In debarker applications, Climax Series C405 Heavy-Duty Locking Assemblies create a 360° contact mechanical interference fit eliminating backlash associated with keyed connections. By eliminating the shaft keyway and associated notch factor, keyless locking devices provide for a shaft that is 30% stronger in both torsion and bending capacity. For sprockets, (more…)

Keyless Locking Device Provides Solution to Expensive Machining Costs in Lumber Handling Systems

Climax Keyless Locking Devices provide timing solutions for lumber handling systems providing a cost-effective maintenance-friendly alternative to traditional keyed connections.

Timber Sawmill Block Kicker

Sawmill Kicker Arm

Lumber handling systems have gears in the transfer station used for lifting raw material. In order for these transfer stations to run smoothly they demand strict sync tolerances. Traditional keyed connections used in lumber handling systems can become compromised causing a loss of synchronization resulting in stopped production. This need to periodically realign the gears and/or replace expensive keyed shafting is often expensive, difficult, and time consuming.

Climax Series C133 Locking Assemblies negate the need for keyways in drive sprocket applications often allowing for the use of A-Plates. When used with kicker arms our keyless locking devices do not require gang broaching or the need to locate keyways on shafting, resulting in reduced machining costs. Under the extreme operating environments of lumber handling systems, KLDs eliminate the need for keyed connections and the associated problems with backlash and fretting corrosion which over time can cause weakened shafts and/or shaft failures.  (more…)

Climax Provide Solutions for Timber Industry

Timber LoggingFrom initial harvesting to final product, machinery used in forestry application is constantly subjected to some of the harshest environments and strenuous loads for which an engineer can design. To compensate, many application designers forgo traditional keys and keyways which are subject to failure and rely upon spline interference fits to mount critical components on rotating shafts.

Keyless shaft/hub locking devices, internal locking (more…)
