FAG 7218-B-XL-TVP Angular Contact Ball Bearing

The FAG 7218-B-XL-TVP is a single-row angular contact ball bearing engineered for high-speed shaft applications requiring simultaneous radial and axial load capacity, with the B 40° contact angle providing greater axial load capacity than the standard A 25° design while maintaining high-speed performance. With a bore of 90 mm, outer diameter of 160 mm, and width of 30 mm, the 7218-B-XL-TVP is the dominant angular contact bearing in Saudi Arabia's high-speed centrifugal pump assemblies, spindle drives for high-precision machine tools, and the pinion shaft positions of industrial gearboxes where axial thrust loads from helical gearing must be simultaneously accommodated with radial gear mesh loads. The XL designation indicates Schaeffler's X-life optimised design incorporating advanced surface finishing and improved geometrical tolerances on the raceways and balls, delivering a measured increase in dynamic load rating of at least 20% over the previous generation — an upgrade that directly translates to extended bearing life at the loads and speeds present in Saudi high-speed rotating equipment.

The TVP designation identifies the high-performance polyamide (PA66) window cage, which is the appropriate cage for this bearing's speed regime. At 90 mm bore, the centrifugal forces on the cage pockets are significant, and the TVP cage's low mass and excellent lubricant retention characteristics produce lower operating temperatures and better grease distribution than the equivalent pressed steel cage at high speeds. The FAG 7218-B-XL-TVP's maximum speed with grease lubrication is 4,300 rpm, and with oil lubrication or oil mist it extends to 5,600 rpm — speeds that encompass the full range of direct-on-line, variable-frequency-driven, and gear-coupled centrifugal pump shaft speeds found in ARAMCO and SABIC high-speed pump assemblies.

In Saudi Arabia, the FAG 7218-B angular contact bearing family is the Schaeffler product most tightly associated with ARAMCO's high-speed centrifugal pump specifications. ARAMCO's pump engineering standards for seawater lift pumps, crude transfer pumps, and gas injection compressor seal oil pumps specify angular contact bearings — most commonly in a back-to-back (DB) or tandem (DF) pair arrangement — that carry both the radial hydraulic loads and the axial thrust from the pump impeller. FAG 7218-B bearings in DB arrangement are the dominant bearing configuration in ARAMCO high-speed centrifugal pump drive ends at pump stations throughout the Eastern Province. SABIC's high-speed recirculation pumps in Jubail cracker feed preheat trains also use FAG 7218-B-XL-TVP in back-to-back pairs to handle combined loading. Razz Middle East stocks both single bearings and pre-matched face-to-face and back-to-back paired sets of FAG 7218-B-XL-TVP, enabling customers to purchase the correct matched pair for pump rebuilds without bearing-to-bearing matching being left to the customer.

Razz Middle East's technical team assists ARAMCO and SABIC maintenance engineers with angular contact bearing arrangement selection — single, paired DB, DT, or DF — and with universal versus paired matched bearing selection, ensuring that the correct preload class and contact angle combination is specified for each pump and compressor application.
