Bearing 4T-33110, T7FC055 for Rexroth original A8V0140 piston pump
Elephant Fluid Power provides hydraulic piston pump bearings, original bearings, the price is reasonable, and will be shipped within 5 days.
When replacing bearings, attention should be paid to the English letters and models of the original bearings. Most of the plunger pump bearings use large load capacity bearings. Purchase the original manufacturer and original specifications. If you replace another brand, you should consult a person who has experience with the bearing to look up the table and exchange, the purpose is to maintain the accuracy level and load capacity of the bearing.
Low density. As the rolling body density decreases, high-speed operation of its centrifugal load is also reduced, which can work at higher speed.
Moderate elastic modulus. Elastic modulus is too large due to stress concentration and reduce the bearing capacity of the bushing.
Thermal expansion coefficient is small. Reduce the sensitivity to temperature changes, so that the bearing operating temperat.
High compressive strength. High compressive strength is the need for high stress for rolling bearings.
High hardness and high toughness. These two properties combine to achieve better surface roughness, and can prevent external par.
Good anti-rolling contact fatigue and has a peel failure mode. Special occasions should have high temperature, corrosion resistance and stability.
