Rexnord Falk T10 Gear Coupling Size 10

The Rexnord Falk T10 gear coupling is a heavy-duty, high-torque flexible shaft coupling designed for the most demanding industrial drive trains found across the oil and gas, petrochemical, cement, and power generation sectors. The T10 series uses an involute tooth profile with a crowned gear contact pattern that accommodates angular, parallel, and axial misalignment simultaneously, protecting connected machinery from shaft reaction forces that would otherwise cause premature bearing failures. At size 10, the T10-10 transmits up to 11,300 Nm of continuous torque with a maximum bore diameter suited to direct coupling of medium-frame centrifugal pumps and compressors that are ubiquitous in Saudi Arabia's heavy industrial landscape.

Rexnord engineers the T10 to API 671 — the standard governing flexible couplings for rotating equipment in petroleum, chemical, and gas industry service. This is a critical requirement for ARAMCO procurement, where API 671 flexible couplings are mandated for pump and compressor drive trains at upstream gathering stations, gas plants, refineries, and downstream petrochemical facilities. The coupling's heat-treated alloy steel sleeve and hub construction, combined with a precision-ground tooth profile, delivers a balance quality of G2.5 at operating speeds and eliminates the need for field trim balancing in most direct-drive pump applications below 3,600 rpm. The flanged sleeve design allows rapid coupling disassembly and tooth inspection without disturbing piping or connected equipment — a significant operational advantage at ARAMCO facilities where planned shutdown windows are measured in hours.

In Saudi Arabia, Rexnord Falk T10 gear couplings are specified at ARAMCO's Ras Tanura and Abqaiq processing plants, at SABIC and SADAF facilities in Jubail Industrial City, and at SWCC desalination stations along the Arabian Gulf and Red Sea coasts where seawater transfer pump trains run continuously under 24/7 service. NEOM's industrial manufacturing zone, currently under development, has also included Falk API 671 couplings in its rotating equipment specifications for utility pump drive trains. The T10's proven performance in ambient temperatures up to 55°C — common at outdoor pump skids across the Eastern Province — makes it the default specification for Saudi-based rotating equipment engineers who must guarantee coupling reliability between turnarounds.

Razz Middle East stocks Rexnord Falk T10 gear couplings and maintains local inventory of common bore sizes and sleeve configurations for rapid delivery to Riyadh, Dammam, Al Khobar, Jubail, and Yanbu. Our engineering team provides bore and keyway selection support, coupling alignment guidance, and installation supervision to ensure every T10 drive train installation meets the API 671 specification requirements of the end user.
