FAQ

What does “PP-A” signify in the KRE 90 PP-A designation?

The “PP” indicates that the bearing is fitted with plastic axial plain washers with formed seal lips on both sides. This provides effective protection against contaminants and retains lubricant. The “A” suffix denotes a specific design or material variation from the standard, often related to internal construction or improved performance characteristics.

What is the correct tightening torque for the M30x1.5 stud?

The correct tightening torque is crucial for proper function and bearing life. For the KRE 90 PP A with an M30x1.5 thread, you must consult the official INA/Schaeffler technical documentation for the exact value for your specific application. Using the incorrect torque can lead to premature failure.

Can this track roller be relubricated?

Yes, INA KRE series track rollers are designed to be relubricated. The stud contains lubrication holes that allow for grease to be introduced. It is essential to use a compatible, high-quality lithium-based grease and follow the machinery’s maintenance schedule to ensure optimal performance and longevity.
