295312000 Atlas Copco Air compressor LOCKNUT

Atlas Copco Air compressor LOCKNUT Main functions

Anti-loosening fixation: During the operation of the air compressor, continuous vibration will occur. The locking nut, through special design (such as threaded structure, additional anti-loosening elements), can effectively prevent the connection components from loosening, ensuring the stable operation of the equipment.

Sealing assistance: At the connection parts involving the air circuit and oil circuit, the locking nut combined with the sealing element (such as O-ring) can enhance the sealing effect, preventing air leakage and oil leakage.

Adjustment and positioning: For some parts, the locking nut can be used to adjust the position of the components (such as pistons, bearings, etc.), and then locked to maintain accuracy.

Atlas Copco Air compressor LOCKNUT Common Types and Features

Self-locking Locking Nut: The nut itself is equipped with a nylon ring, metal insert, or special thread structure, achieving anti-loosening through friction. It is suitable for parts with low vibration.

Slotted Locking Nut (with opening pin): The nut has a slot that fits with the bolt hole, and an opening pin is inserted for locking. The anti-loosening effect is reliable and is often used for components with high-speed rotation or severe vibration (such as crankshaft ends).

Flange Surface Locking Nut: The bottom has a flange edge, increasing the contact area and having both anti-loosening and pressure dispersion functions. It is suitable for thin components connections.

High-strength Locking Nut: Made of 8.8 grade or higher high-strength steel, the surface is often treated with galvanization or phosphating, resistant to wear and corrosion, suitable for high-pressure component connections.

Selection and Installation Considerations

Matching Specifications: Select the corresponding nut based on the bolt model (diameter, pitch) of the connection part to avoid specification mismatch and connection failure.

Torque Requirements: When installing, follow the torque specified in the equipment manual. Loosening due to insufficient torque is possible, while excessive torque may cause thread deformation or component damage.

Regular Inspection: Due to long-term vibration, the locking performance may decline. Regular inspection and re-tightening are necessary, especially during maintenance and servicing, and cannot be ignored.

It is recommended to refer to the model parameters and original factory accessory standards of Atlas Copco Air compressor LOCKNUT to ensure that the performance of the locking nut matches the equipment operating conditions, ensuring safe operatio
