RE16025 Crossed Roller Bearing - FAQ
Does the RE16025 require frequent lubrication?
Not in most applications. With proper initial greasing, maintenance intervals are generally long, though high-speed or continuous-duty setups may require periodic relubrication.
How sensitive is the RE16025 to installation error?
Very sensitive. Crossed roller designs rely on accurate geometry; small deviations in bore roundness, shoulder height, or bolt torque can alter internal clearance.
Can preload loss occur over time?
Yes. Thermal expansion, settling of mating parts, or degraded lubricant film can gradually reduce preload, affecting stiffness and precision.
