The 75tVB344 Thrust ball bearings mainly consist of a shaft ring (which mates with the shaft), a housing ring (which mates with the bearing housing), steel balls, and a cage. They feature a separable design for easy installation and maintenance. Some models include dust covers or sealed structures.

Thrust ball bearings have high axial load capacity, are suitable for bearing pure axial loads, have high limiting speeds, low friction coefficients, and smooth operation. Their separable structure simplifies installation, results in a compact size, and minimizes space requirements.
