Standard tolerances for FBKW 31 • JAW-FLEX coupling selections equivalent to 32 Competitor’s Couplings . R-PM-J-01/02-01/14 Page 3 JAW-FLEX COUPLING STANDARD FEATURES • Simple in construction • No need of lubrication • Low initial & operational cost • Provides torsional vibration isolation and damping • No metal to metal contact, hence

All Roads Lead to Regular Alignment While flexible couplings are designed to withstand (without damage) some shaft misalignment, it doesn't 

Since most flexible couplings have two flex planes (or points of articulation), the spacer coupling tolerances may safely be used, even with 

Reuland flexible couplings are precision machined. By maintaining tight tolerances, we help eliminate vibration and noise. Alignment is easily made with a straight edge and a feeler gage. Reuland flexible couplings offer double set screws standard. Most manufacturers charge you extra for a double set screw option. Since our couplings are

The primary torsional coupling uses a resilient elastomer as the flexing medium. All of the couplings described in the elastomeric section of the handbook have been used on torsional service with varying degrees of success. The elastomeric types described in the following section are the couplings with the best attributes for torsional service.

Coupling Alignment: - Before moving the equipment in place for alignment, the Drive Ring must be placed behind the winged section of the Flex Hub (lobe side 

Based on the manufacturer's recommendations, this coupling can tolerate a fairly substantial amount of misalignment. And, since the insert is 

The "Acceptable" Offset shaft alignment tolerance for 1800 RPM is 4.0 mils. That is 3.75 to 8 times better than the elastomeric coupling tolerance and 1.3 to 3 times better than the grid style coupling tolerance. The goal of precision shaft alignment is to make the rotational centerlines of the machines collinear when in operation.

Select a coupling for reversing service to connect a gear drive low-speed shaft to a runout mill table roll . The electric motor rating is 50 hp at the base speed and the system peak torque at the coupling is estimated to be 150,000 lb-in . Coupling speed is 77 rpm at the motor base speed . The drive shaft diameter is 4 .000 with a keyway of 1

Flexible Shaft Couplings. In many cases machine designers give limited thought to flexible shaft couplings. They devote their time to the more expensive components, overlooking the fact that the performance of a machine is only as good as the connections of its shafts. Reliance is fully aware of the importance of the shaft coupling and that

If we look at the table under 1,800 RPM, which is the most common RPM in the industry, it shows the allowable tolerances divided into three ranges: Minimal - 6.0 mils of offset and 1.2 mils per inch of angle. Standard - 3.0 mils of offset and 0.6 mils per inch of angle. Precision - 1.6 mils of offset and 0.3 mils per inch of angle.
