KB075XP0 Bearing Structural Features & Performance Benefits
Four-Point Contact Design: The optimized raceway geometry enables the bearing to support combined radial and axial loads in any direction with a single bearing row, providing exceptional load moment capacity (4568 lbf dynamic, 12380 lbf static).
Thin-Section Construction: With a consistent 0.3125" cross-section regardless of bore size, this bearing delivers maximum performance in minimal space, making it ideal for compact machinery design.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore/OD tolerance: -0.0012" to 0") ensures smooth operation and precise positioning in high-accuracy applications.
Premium Materials: Constructed from chrome steel rings and balls with a brass cage for optimal strength, durability, and reliable performance under demanding conditions.
