This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are tied to the anareus.cz domain.AirsoftParts ball bearing with nut and screw serves as a replacement part for the piston head in an AEG air seal system. The axial bearing is positioned on the rear of the piston head and allows the spring to rotate more freely around its longitudinal axis during compression. This reduces torsional stress generated during the spring's operating cycle and contributes to proper function. The set is suitable for servicing, replacing a damaged or worn bearing, or assembling a compatible piston head. Along with the bearing, the set also includes a nut and mounting screw, providing the components required for installation. Exact compatibility with specific piston heads is not specified in the source data, so it is advisable to check the dimensions and design of the original part before installation.
The bearing allows the spring to rotate more freely during compression and reduces unwanted torsional stress during its operating cycle.
The set is designed as a service replacement for the bearing located beneath the piston head in a compatible AEG piston assembly.
The ability to rotate helps the spring release torsional stress generated during compression, supporting proper operation of the spring assembly.
Along with the axial bearing, you also receive the corresponding nut and mounting screw for installation beneath the piston head.
During servicing, it allows you to replace the bearing and its mounting components separately without purchasing a complete piston head if its body is still usable.
The bearing allows the spring to rotate more freely during compression. This reduces torsional stress and unwanted twisting during its operating cycle.
Yes. Along with the axial ball bearing, the package includes a nut and mounting screw.
Universal compatibility is not specified in the source data. Before replacement, we therefore recommend comparing the design and dimensions of the original bearing, nut and screw with this replacement set.
If the compatible piston head itself is undamaged and the issue concerns only the bearing or its mounting components, servicing can be carried out by replacing this separate set.
