It supports the drive shaft and stabilizes mechanical components that regulate air intake during load and unload operation. In industrial operation, the inlet valve system continuously adjusts airflow based on demand. Therefore, repeated mechanical motion places continuous stress on internal bearing structures. As a result, the kit helps maintain stable valve movement and consistent response behavior throughout the service cycle. In addition, typical applications include pharmaceuticals, electronics manufacturing, and food processing. These industries require oil-free compressed air and stable operational conditions. 2906044300 INLET BRG BLOCK KIT Atlas Copco ZR-ZT Oil-Free Compressors (1) Technical Specifications Part Information Part Number: 2906044300 / 2906-0443-00 Product Type: Inlet Bearing Block Service Kit Origin: Belgium (BE) Tariff Code: 84831095 Physical Data Specification Value (Metric) Reference (Imperial) Length 185 mm 7.3 in Width 115 mm 4.5 in Height 30 mm 1.2 in Weight 216 g 7.6 oz Kit Components Item Description Quantity 1 Block Mounting 1 2 Washer 2 3 Shaft Drive 1 4 Locknut 1 2906044300 INLET BRG BLOCK KIT Atlas Copco ZR-ZT Oil-Free Compressors (2) Application and Compatibility The 2906044300 inlet bearing block kit fits Atlas Copco stationary oil-free compressor platforms. It is commonly applied in ZR and ZT series machines that operate under continuous industrial workloads. Compatible Compressor Series ZR300 ZR315 ZR355 ZR400 ZR425 Selected ZT oil-free compressor models Specific ZA stationary oil-free configurations Installation Position The kit installs inside the inlet valve assembly housing. It supports the drive shaft mechanism that opens and closes the inlet valve during compressor load regulation cycles. Moreover, this installation position experiences continuous mechanical movement and vibration. Therefore, operators should include it in scheduled preventive maintenance programs. 2906044300 INLET BRG BLOCK KIT Atlas Copco ZR-ZT Oil-Free Compressors (3) Functional Principle and Wear Behavior During compressor operation, the inlet valve system continuously switches between load and unload conditions based on air demand. The system drives this motion through a shaft mechanism supported by the bearing block structure. Over extended operating hours, mechanical contact and cyclic loading gradually affect internal alignment and tolerance levels. Consequently, valve response behavior may change, and mechanical smoothness may decrease. However, the bearing block kit helps maintain proper shaft alignment. In addition, it supports stable motion transfer within the inlet system. As a result, the system maintains more consistent valve performance during long-term operation. Preventive Maintenance Guidance The 2906044300 inlet bearing block kit serves preventive maintenance applications. Atlas Copco recommends a replacement interval of up to 8000 operating hours or every two years, depending on operating conditions. Therefore, replacing the kit within scheduled maintenance cycles helps maintain stable inlet valve function. In addition, technicians often install it together with related inlet valve service components during major overhauls. As a result, this maintenance strategy helps reduce performance degradation caused by mechanical wear in the inlet system and supports stable compressor operation. 2906044300 INLET BRG BLOCK KIT Atlas Copco ZR-ZT Oil-Free Compressors (4) Genuine Atlas Copco Engineering Quality The 2906044300 kit follows Atlas Copco engineering and manufacturing standards for oil-free compressed air systems. Each component meets precise mechanical tolerances required for inlet valve operation. Furthermore, genuine Atlas Copco components maintain system consistency across the compressor lifecycle. Each part integrates directly with the original mechanical configuration of ZR and ZT compressor platforms.
