71807 ACD/P4TBTLVT105 Bearing Product Overview & Core Advantages
The 71807 ACD/P4TBTLVT105 is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This matched arrangement bearing set features a Triplex Back-to-Back (TBT) configuration, providing superior stability and the ability to withstand combined loads (radial and axial). Manufactured to P4 tolerance class, it ensures high running accuracy and is preloaded for immediate, precise operation. Its compact design and high rigidity make it ideal for high-speed, high-precision spindles and machinery.
71807 ACD/P4TBTLVT105 Bearing Model Code Explained, Specifications & Naming Convention
The model number 71807 ACD/P4TBTLVT105 provides detailed technical specifications:
- 71807: Basic bearing series and size designation (35mm bore, 47mm OD).
- ACD: Angular Contact design with a 25° contact angle.
- P4: Indicates a high-precision tolerance class for superior running accuracy.
- TBT: Specifies the Triplex Back-to-Back matched arrangement of three bearings.
- LV: Denotes a light preload for optimal rigidity and minimal deflection.
- T105: Indicates the use of a specific, high-performance grease lubrication.
71807 ACD/P4TBTLVT105 Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The Triplex Back-to-Back (TBT) arrangement of three bearings creates an extremely rigid bearing system, effectively resisting complex moment loads and maintaining shaft positioning under heavy combined loads.
- Precision Performance: Manufactured to P4 tolerance class with a 25° contact angle, this bearing delivers high running accuracy and is optimized for applications requiring minimal runout and vibration.
- High-Speed Capability: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces and enabling higher limiting speeds (56,000 rpm).
- Optimized for Preload: The bearing set is supplied with a light preload (LV), eliminating internal clearance for immediate high stiffness and precision without requiring additional adjustment during installation.
71807 ACD/P4TBTLVT105 Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Robotics: High-accuracy joints and arm assemblies.
- Medical Equipment: Dental handpieces and surgical drill spindles.
- Aerospace Actuators: Control surface mechanisms requiring high reliability.
