Air Handling Bearing

Table of Content [Hide]


    The LDK Air Handling Series is designed for a wide variety of highly demanding HVAC and air handling applications.


    Applications

    Exhaust  Fans, Heating  Fans, Blowers, Heating  Equipment, Cooling Towers, Exhaust Ventilators etc.

    Special features

    • 100%noise tested to Electric Motor Quality (EMQ) standards.

    • 100%testing of alignment  torque.

      Bearings and housings are individually matched to achieve an air handling fit, an unique set of tolerance to ensure easy alignment and prevent bearing pre-load when mounting onto a lightweight frames.

    • Each bearing is manufactured with AlSI 52100 bearing steel,G10 grade steel ball, low noise retainer and low noise grease.

    • Smaller bore tolerance allows for a tighter fit with the shaft. This in turn,reduces vibration and noise and dramatically increases bearing life.

    • Internal bearing clearance is defined as the allowable space between the rolling elements and raceways. LDK uses an appropriate clearance which reduces the noise and vibration in high speed applications.

    • Non-Contact seal is available for the lighter torque.

    • Nylon patched grub screw is proven to provide greater locking power between the bearing and the shaft.

    Advantages and benefits

    LDK Accu-Grip(R) bearing units are designed to produce 360 degrees of equalized locking contact. The shaft is centered concentrically in the bore of the bearing and always runs true. Shaft offset is eliminated and premature locking failure is minimized. Since locking design is a major factor in mounted bearing performance, Accu-Grip(R)stands out as a major advantage.

    • Quick assembly with minimum effort. Only one cap screw to tighten down, in one position!

    • Simplify equipment maintenance and lower replacement/maintenance time and cost.

    • Quiet running. Vibration and noise significantly reduced.

    • Increase manufacturing productivity. Reduce inventory and ordering complexity.
