3000A Series

The 3000A series double row angular contact ball bearings are engineered with a specific internal geometry that facilitates the handling of combined radial and axial loads. Unlike single row variants, the 3000A series features a specialized design with a contact angle that enables rigid shaft support and the ability to accommodate tilting moments. These bearings consist of a solid outer ring, a one-piece inner ring, and ball and cage assemblies typically constructed from glass fiber reinforced polyamide or pressed steel. The internal construction ensures precise ball guidance and optimized load distribution, making them suitable for applications where space is limited but high load-carrying capacity is required. They are commonly supplied in open or sealed configurations to meet specific environmental demands.

Core Technical Advantages

  • Bi-directional Axial Load Capacity: The double row arrangement allows the bearing to support axial forces in both directions simultaneously with radial loads.
  • Enhanced Rigidity: The specialized contact angle design provides a high degree of stiffness, reducing shaft deflection during operation.
  • Compact Envelope: Offers the functionality of two single row angular contact bearings in a significantly reduced axial width, optimizing installation space.
  • High Speed Capability: Optimized internal raceway finishes and cage designs minimize friction, allowing for high rotational speeds with controlled heat generation.

Product Technical Characteristics

  • Contact Angle: Designed with a standard contact angle that balances radial and axial load distribution.
  • Cage Materials: Available in Polyamide (TVH) for low-noise operation or Pressed Steel for high-temperature stability.
  • Sealing Options: Available with 2Z (metal shields) or 2RS (lip seals) for protection against dust, debris, and lubricant leakage.
  • Dimensional Standards: Manufactured in accordance with ISO 15 boundary dimensions for global interchangeability.
  • Lubrication: Sealed variants are pre-filled with lithium-base grease suitable for operating temperatures ranging from -30°C to +110°C.

Typical Application Scenarios

  • Automotive Systems: Integrated into air conditioning compressors, wheel hubs, and tensioner pulleys.
  • Industrial Pumps: Used in centrifugal pumps to manage the axial thrust generated by fluid movement.
  • Agriculture Machinery: Support for disc harrows, seeders, and conveyor systems exposed to combined loads.
  • Electric Motors: Provides stable shaft positioning for medium-sized industrial motors and household appliances.
  • Power Transmission: Utilized in gearboxes and reduction drives requiring precise gear meshing.

Storage and Operational Guidelines

  • Storage Conditions: Store in a cool, dry environment with a relative humidity not exceeding 60%. Keep bearings in their original unopened packaging to prevent corrosion.
  • Handling Precautions: Use specialized induction heaters or mechanical mounting tools. Do not apply mounting forces through the rolling elements to avoid raceway brinelling.
  • Alignment Accuracy: Ensure shaft and housing alignment is within 0.001 to 0.003 radians; excessive misalignment leads to premature cage wear and increased operating temperatures.
  • Lubrication Check: For open bearings, verify compatibility between the factory-applied rust preventative and the operational lubricant before final assembly.
