Tungsten Carbide Radial Bearings

4140 and 4340 alloy steel materials are most commonly used for the base material of our radial bearings. Custom steels are available upon customers request. Customer may also choose to use various tungsten carbide shape configurations including but not limited to rounds, hexagon, rectangular, and grain style.

Documentation such as material certifications as well as heat treatment and certificates of conformity can be supplied with each shipment. Part and traceability numbers can be included on every part for ease of tracking and verification.

Custom designs and prototypes are welcomed as well as small batch orders. Expedited deliveries can be arranged at time of order. Tungsten carbide bearings can also be ordered in either oversized or undersized configurations to fit customers special requirements.

Grain Style TC Bearings

• Average hardness of carbide grain matrix: > 70 HRC.

• Average substrate body hardness: 28-36 HRC. (Different values provided upon customers request)

• Common sizes available include but are not limited to: 2 1/8”, 2 3/8”, 2 7/8”, 3 3⁄4”, 4.75”, 5”, 6.25”, 6.50”, 6.75”, 7.75”, 8”, 9 5/8”, and 11 1⁄4”

• Grain styles perform best in enclosed environments of oil. Under magnification it has been noted that oil accumulates in the areas where washand erosion of the matrix happen. This holds tiny pockets of oil, which helps in lubrication of the bearings.

• Typical life expectancy: 300 – 400 hours (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)

• Tungsten Carbide layer can be applied in various thicknesses with our unique processing.
