FAG 6312-C3 Deep Groove Ball Bearing

The FAG 6312-C3 is a heavy-series deep groove ball bearing engineered for higher radial and axial load capacities than the medium-series 6200 and 6300 families, making it the preferred bearing choice for medium-power electric motors from 37 kW to 90 kW, larger centrifugal pumps, and gearboxes in Saudi Arabia's process industries. With a bore of 60 mm, outer diameter of 130 mm, and width of 31 mm, the 6312-C3 occupies the sweet spot for motors on the DE-400 and EFF1 premium-efficiency frames deployed throughout ARAMCO's gas compression stations and SABIC's Jubail ethylene crackers. The C3 clearance class again ensures safe operation in elevated ambient temperatures, which in Saudi Arabia's Eastern Province regularly reach 48°C in outdoor summer conditions — a regime that causes significant differential heating between the inner ring (which runs at shaft temperature) and the outer ring (at housing temperature).

Schaeffler's 6312-C3 achieves a basic dynamic load rating of 81.9 kN and basic static load rating of 51.0 kN, placing it firmly in the category of bearings capable of handling the starting torque transients and load spikes common in Saudi process plant equipment. The cage design — pressed steel in the standard variant, optionally brass (M) for higher-temperature or higher-speed applications — ensures even ball spacing and retains grease between re-lubrication cycles. At 8,000 rpm grease limiting speed, the 6312-C3 is well suited for the vast majority of four-pole and six-pole industrial motors in Saudi Arabia without supplementary cooling or oil lubrication.

FAG 6312-C3 bearings are in daily demand across Saudi Arabia's industrial maintenance sector. ARAMCO Gas Operations in Uthmaniyah, Shedgum, and Haradh uses them for preventive and corrective maintenance on gas compressor motor drive-end bearings, where bearing replacement cycles are tied to turnaround schedules and any delay in parts availability cascades directly to production impact. SABIC's on-site maintenance organisations at Yanbu and Jubail carry 6312-C3 as a fast-moving MRO spare for steam turbine auxiliary pump motors and agitator drives in polymerisation reactors. Vision 2030 infrastructure projects including Riyadh Metro maintenance depots and NEOM utility pump stations are generating new demand for FAG 6312-C3 in high-reliability pump and fan motor applications. Razz Middle East stocks the 6312-C3 alongside the full Schaeffler FAG deep groove ball bearing range and can source specialist variants — including the 6312-M brass cage, 6312-2Z shielded, and 6312-2RSR sealed options — within short lead times.

As an authorised Schaeffler distributor, Razz Middle East provides technical data sheets, lubrication specifications, and bearing selection consultations to our Saudi customers at no additional cost, ensuring that the correct bearing variant is selected for each application and that the expected bearing life is achieved in practice.
