For tough applications where strength and affordability are important, the steel design of rigid compression couplings is well suited. Timken cast steel couplings are an excellent choice for joining two shafts of the same size. This type of coupling is also known as a “rigid clamp style” coupling. Choose from standard sizes for shafts 1-7/16 […]
Timken Quick-Flex couplings
Timken Quick-Flex elastomeric couplings are durable enough to face the challenges of harsh environments, yet need minimal maintenance. They are easy to install and require no lubrication. Timken Quick-Flex couplings operate without any metal-to-metal contact. Because the metal hubs don’t wear, the elastomeric insert is the only spare part users will need. For especially harsh […]
The year in couplings 2016: GAM
For this multi-part series, Coupling Tips.com reached out to several coupling industry professionals to get their take on the year in couplings. Here, GAM Technical Marketing Manager, Mike Parzych looks back on 2016 and gives a few predictions for the new year. Coupling Tips: What do you think was the biggest event in the industry […]
Basics: What is a clamping screw
Clamping screws are machine elements which use screw thrust for workpiece fixing and positioning. Point contact by the full ball securely fixes the workpiece. Advantages of using Clamping Screws By replacing hex socket head cap screws and hex socket set screws with clamping bolts when clamping (fixing) workpieces, point contact with workpieces can be achieved. […]
Shaft collars and couplings machined from 316 stainless steel
A full line of 316 stainless steel shaft collars and couplings that are designed for harsh process environments such as waste water treatment is available from Stafford Manufacturing Corp. of Wilmington, Massachusetts. Stafford 316 SST Collars and Couplings are designed to withstand constant exposure to harsh chemicals, solvents, detergents, and water found in mixing equipment, […]
Bellows-type flexible couplings: NBK specifications
Bellows-type flexible couplings from NBK allows for eccentricity, angular misalignment, and end-play. The bellows is stainless steel. MBB couplings work extremely well with servomotors and stepper motors, but are inappropriate for pairing with general-purpose motors. MBB couplings are zero-backlash couplings, though slightly less forgiving of misalignment than come other compliant types. Bellows-type flexible couplings: Selection example Note that […]
NBK’s MJ jaw couplings for power-transmission designs
NBK’s MJ jaw couplings are suitable for power-transmission designs. They can transmit high torque and address reasonable levels of misalignment. They also impart vibration absorption … … just a few reasons why jaw types are widely used in PT applications. If an application needs the coupling to address more misalignment, NBK offers MOR Oldham-type couplings. […]
Dual purpose of miniature couplings:motion control and power transmission
How to select couplings A simple and generally used method to select the most suitable coupling is the four step approach. That is, 1. Select the coupling type suitable to the intended usage 2. Select the material of the coupling in line with the environment of usage 3. Select the coupling size fitted to the […]
Video: NBK on precision coupling selection for factory automation applications
There are many ways to improve the productivity in the Servo System. For example, there is the possibility that you can shorten the production cycle time if you use a high performance servo motor and an actuator. There are also many different kinds of couplings. In this video, NBK explains the basic points on how […]
High-gain rubber couplings from NBK
NBK America now offers the XG Series of couplings. Why? TO keep pace with the evolution of servomotors. Couplings today are a key component for helping servomotor-driven setups deliver speed-response frequencies … without the problem of vibration that usually accompanies such designs. In fact, it’s difficult to get maximum servomotor performance with high-rigidity couplings such as […]
