The bearing function of an axial piston pump is to support and facilitate the rotation of the rotating parts of the pump (mainly the swash plate and pistons). Bearings in axial piston pumps are designed to withstand the radial and axial loads generated during operation and provide smooth and reliable rotation. The following are the main functions and characteristics of bearings in axial piston pumps: 1. Load support: Bearings bear the mechanical loads generated by the rotating parts of the pump, including the swash plate and pistons. They help distribute the load and prevent excessive wear or damage to the pump's internal parts. 2. Axial Stability: Bearings help maintain the axial stability of rotating parts. They ensure that the swashplate and pistons remain in proper alignment and contact for efficient and consistent pumping action. 3. Low Friction: The bearings are designed to minimize friction and energy loss during operation. This helps to increase the overall efficiency of the pump by reducing power consumption and heat generation. 90-R-130-HS-5-CD-80-P-3-F1-H-03-GBA-23-23-28 90R130HS5CD80P3F1H03GBA232328 90R130-HS-5-CD-80-R-3-F1-H-03-GBA-35-35-24 90R130HS5CD80R3F1H03GBA353524 90-R-130-HS-5-CD-80-R-3-F1-H-03-GBA-35-35-24 90R130HS5CD80R3F1H03GBA353524 90R130-HS-5-CD-80-S-4-F1-F-03-GBA-35-35-24 90R130HS5CD80S4F1F03GBA353524 90-R-130-HS-5-CD-80-S-4-F1-F-03-GBA-35-35-24 90R130HS5CD80S4F1F03GBA353524 90R130-HS-5-DE-80-R-4-F1-H-00-GBA-17-26-24 90R130HS5DE80R4F1H00GBA172624 90-R-130-HS-5-DE-80-R-4-F1-H-00-GBA-17-26-24 90R130HS5DE80R4F1H00GBA172624 90R130-HS-5-DE-80-S-4-C8-F-03-GBA-42-42-24 90R130HS5DE80S4C8F03GBA424224 90-R-130-HS-5-DE-80-S-4-C8-F-03-GBA-42-42-24 90R130HS5DE80S4C8F03GBA424224 90R130-HS-5-DE-80-S-4-F1-H-00-GBA-42-42-30 90R130HS5DE80S4F1H00GBA424230 90-R-130-HS-5-DE-80-S-4-F1-H-00-GBA-42-42-30 90R130HS5DE80S4F1H00GBA424230 90R130-HS-5-NN-80-L-3-F1-F-03-GBA-35-35-24 90R130HS5NN80L3F1F03GBA353524 90-R-130-HS-5-NN-80-L-3-F1-F-03-GBA-35-35-24 90R130HS5NN80L3F1F03GBA353524 90R130-HS-5-NN-80-L-3-F1-H-06-GBA-38-38-24 90R130HS5NN80L3F1H06GBA383824 90-R-130-HS-5-NN-80-L-3-F1-H-06-GBA-38-38-24 90R130HS5NN80L3F1H06GBA383824 90R130-HS-5-NN-80-R-3-C8-H-03-GBA-42-42-24 90R130HS5NN80R3C8H03GBA424224 90-R-130-HS-5-NN-80-R-3-C8-H-03-GBA-42-42-24 90R130HS5NN80R3C8H03GBA424224 90R130-HS-5-NN-80-R-4-C8-H-03-GBA-42-42-26 90R130HS5NN80R4C8H03GBA424226 90-R-130-HS-5-NN-80-R-4-C8-H-03-GBA-42-42-26 90R130HS5NN80R4C8H03GBA424226 90R130-HS-5-NN-80-R-4-F1-F-00-GBA-20-20-24 90R130HS5NN80R4F1F00GBA202024 4.
