LOVEJOY 68514470006 SS Type Hub SS075, 1/4 Inch Bore Size, Without Keyway

Features:

• Lovejoy SS075 couplings feature three components; two units of SS075 jaw coupling hubs and a spider of the same series.
• Lovejoy 68514470006 SS type hub is used for power transmission and accommodating shaft misalignment in gearboxes, electric pumps, motors, blowers and compressors.
• It transfers misalignment and shock to the central part of the coupling for wear minimisation.
• This SS hub features finished bores to ensure rust protection and is capable of performing even in case of elastomer failure.

Frequently Asked Questions:

Q. What are the steps to choose the right jaw coupling hub?

A.

• Determining the usage.
• Choosing the material considering the intended application environment.
• Selecting the coupling on the basis of torque, speed and bore size.
• Jaw coupling hub types are based on usage and their ability to handle the degree of movement or rotation. For example, curved jaw coupling hubs (Lovejoy CJ Series) transfer high torque and can handle some degree of rotation (backlash) due to their curved jaw design.

Q. What is the difference between keyway and keyless jaw coupling hubs?

A. Jaw coupling hubs feature a cutout slot, known as keyways that fit in the shaft keys. These keys promote improved torque & prevents slipping, as well as reduce losses caused by vibrations & backlash (degree of free movement between two rotating, mating parts). However, some applications do not require keys, as keyless jaw coupling hubs use only set screws to transfer torque. Keyless hubs are ideal for situations which remain unaffected even if the shafts slip.

Q. What frequent mistakes are made when selecting a jaw coupling hub?

A.

• Failing to check the maximum bore capacity: Users should always check the shaft size of the driven equipment before choosing the jaw coupling.
• Using the same-sized couplings everywhere: It may seem like a good idea to prevent downtime. But an oversized or undersized jaw coupling may cause motor malfunctioning.
• Ignoring heat and chemical compatibility: Since the jaw couplings require buying both hubs and spiders, one should ensure that they're both compatible with each other.
• Overlooking space restrictions: Make sure that the selected couplings can fit the provided space. High torque applications usually require either a large diameter coupling or a coupling with multiple configurations & high torque density.
