Description
NSK FB505002 belongs to needle roller thrust bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for FB505002 and any equivalents.
When axial space is tight but thrust capacity is still required, the NSK FB series needle thrust bearing provides a thin, caged assembly with support washers. This series is common in gearboxes, clutches, pumps, and machine tools. MR Industrial Accessories supplies it to customers across the United States and Latin America, quoting by part number through WhatsApp or email and helping with equivalent selection.
The FB series covers sizes such as FB502002, FB503002, FB503503, FB504001, FB504501, FB505002, and FB505501. Each part number encodes the size: the first digits typically relate to the shaft diameter or nominal bore, while the remaining digits indicate outer diameter or assembly width. For a correct match, provide the full part number along with the mounting dimensions.
These bearings are found in automotive, metalworking, food processing, and petrochemical plants. Typical equipment includes gearboxes, clutch mechanisms, water and oil pumps, compressors, machine tools, and lifting gear. Their low profile fits where other thrust bearings cannot, and they handle unidirectional axial loads.
To select the right FB bearing, confirm the shaft diameter, housing outer diameter, and total height. The needle cage must be centered, and any support washers properly seated. Grease or oil lubrication can be used depending on the environment; in contaminated areas, consider additional seals. Proper alignment of the support surfaces is essential to prevent edge loading and premature wear.
Interchange with other brands is possible when the dimensional nomenclature matches. If you have a part number from another manufacturer or an unidentified bearing, send us the shaft, outer, and height measurements, and we will identify a compatible equivalent. MR Industrial Accessories supplies the NSK FB series and provides selection support for a correct replacement.
To request a quote for an FB series needle thrust bearing, send the complete part number via WhatsApp. If the exact reference is not available, share the measurements or a photo of the part, and we will respond promptly with a quotation.
