Product Description
Product Overview
This product is a multi-tooth anti-looseness sun washer complying with GB/T9160.2 standard, manufactured from high-quality steel and subjected to blue and white zinc plated surface treatment. The washer is sunflower-shaped, with multiple circles of small external teeth and internal teeth distributed radially. During installation, the external teeth of the washer will bite into the contact surface of the bearing housing or shell, and the internal teeth will bite into the end face of the shaft shoulder or lock nut. A strong anti-rotation resistance is formed through the mechanical engagement effect of the multi-tooth, which effectively prevents the bearing from loosening due to vibration or rotation during operation. The blue and white zinc coating provides basic rust protection, ensuring reliable application in various industrial environments.
Core Advantages
-
Excellent Mechanical Anti-Looseness: The internal and external multi-tooth design forms a two-way mechanical lock, with extremely reliable anti-looseness effect and strong anti-vibration capability.
-
Precise Axial Positioning: Provides precise axial positioning for the bearing, preventing the bearing from axial movement.
-
No Additional Locking Device Required: Simplifies the bearing assembly structure and can usually replace the combination of stop washer and lock nut.
-
Easy Installation and Reusable: Under the recommended installation method, it can be disassembled and repositioned for use (Note: The integrity of the teeth should be checked for reuse).
Applicable Industries
-
Various Bearing Applications: Axial positioning and anti-looseness of rotating components such as deep groove ball bearings, tapered roller bearings and self-aligning roller bearings.
-
Industrial Transmission and Gearboxes: Fixation of bearings in equipment such as reducers, gearboxes and transmission shafts.
-
Motors and Generators: Anti-looseness and positioning of bearings in high-speed rotating components such as various motor spindles and generator rotors.
-
Automotive and Construction Machinery: Fixation of bearings in parts such as hub units, gearboxes, differentials and heavy-duty axles.
-
Agricultural and Mining Machinery: Bearings subjected to high vibration loads in heavy-duty equipment such as harvesters, tractors and crushers.
-
Pumps, Valves and Fluid Equipment: Fixation of bearings for rotors in equipment such as centrifugal pumps, hydraulic motors and compressors.
-
Wind Power and New Energy Equipment: Anti-looseness of bearings in key parts such as wind turbine gearboxes, spindles and electric vehicle drive motors.
Warm Tips
-
Before installation, please ensure that the contact surfaces of the bearing housing and shaft shoulder are clean, flat and have sufficient hardness to ensure effective tooth engagement.
-
Please use special installation tools or methods to ensure that the washer is evenly compressed, so that the internal and external teeth are completely embedded into the contact surface.
-
The blue and white zinc coating provides basic protection; in extremely humid or corrosive environments, it is recommended to evaluate its applicability or take additional protective measures.
