ZKLF40100-2RS-2AP-XL
Axial радиально-упорный шарикоподшипник
Double-row sealed precision bearing with matched pair configuration. P4 grade accuracy for ball screw support and ось вращения applications in demanding CNC machine tool environments.
ZKLF40100-2RS-2AP-XL / Axial радиально-упорный шарикоподшипник
The ZKLF40100-2RS-2AP-XL is a precision double-row axial angular contact шарикоподшипник, purpose-designed for ball screw support and machine tool ось вращения applications. The "2RS" designation indicates dual rubber seals on both sides, providing excellent contamination protection while retaining factory-filled смазка пластичной смазкой for the bearing's entire срок службы. The "2AP" suffix denotes a matched pair configuration, ensuring uniform preload distribution when two bearings are installed in tandem, face-to-face, or back-to-back arrangements.
Manufactured to P4 (ABEC-7) precision standards, this bearing обеспечивает the high running accuracy and low runout essential for precision ball screw support in CNC machine tools. The double-row angular contact design обеспечивает high axial жёсткость in both directions, supporting thrust loads generated during ball screw operation while maintaining precise axial positioning. Steel balls in a reinforced cage ensure reliable высокоскоростной performance. Typical applications include ball screw support bearings in обрабатывающий центрs, lathe axis drives, grinding machine feed screws, and поворотный стол support in precision indexing equipment.

Почему выбирают ZKLF40100-2RS-2AP-XL
Разработано для precision ball screw support and ось вращения applications, this bearing обеспечивает the accuracy, жёсткость, and reliability demanded by modern CNC machine tools.
P4 Precision
ABEC-7 equivalent grade обеспечивает exceptional running accuracy with runout held to 0.002mm or less, ensuring precise ball screw positioning and minimal vibration in CNC machining operations.
Double Row Design
Two rows of balls with 60° contact angle provide high axial жёсткость in both directions, supporting thrust loads generated during ball screw acceleration and deceleration.
Закрытый for Life
2RS dual rubber seals provide robust contamination protection while retaining factory-filled high-grade grease, eliminating the need for relubrication over the bearing's entire срок службы.
Matched Pair
2AP matched pair configuration гарантирует uniform preload distribution when two bearings are installed together, eliminating the need for on-site shimming and simplifying spindle assembly.
High Axial Жёсткость
The 60° contact angle and double-row arrangement provide superior axial stiffness compared to standard angular contact designs, critical for maintaining positional accuracy under thrust loads.
Ball Screw Support Optimized
Purpose-designed for ball screw support bearing arrangements in обрабатывающий центрs, lathes, and grinding machines. Provides the precise axial guidance essential for sub-micron positioning accuracy.
