1125 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The 1125 thrust bearing features optimized bearing dimensions (125mm bore × 175mm OD × 46.5mm width) and precision-engineered components to deliver exceptional axial load carrying capacity. The chrome steel construction of all critical components ensures maximum strength and longevity under heavy thrust conditions.
Precision Engineering: With tight dimensional tolerances (bore: -0.025mm to 0, width: +0.025mm to -0.4mm), this bearing provides consistent performance and reliable operation in precision applications. The 1mm chamfer dimension facilitates proper installation and alignment.
Performance Characteristics: The bearing achieves a limiting speed of 1,900 rpm while maintaining structural integrity. The open design allows for optimal lubrication flow, critical for high-speed thrust applications. The temperature range of -30° to 110°C ensures reliable operation across various environmental conditions.
