Super Precision Roller Bearings

Description

Basic Parameters

Super Precision Roller Bearings are engineered for applications requiring high rigidity, exceptional load capacity, and outstanding rotational accuracy. These bearings are typically designed to accommodate heavy radial loads and moderate axial loads, making them ideal for high-speed and high-precision environments. Key parameters include:

Bearing Type: Cylindrical Roller Bearings or Tapered Roller Bearings (depending on application)

Precision Class: ISO P4, P2 or equivalent JIS Class 4/2, ensuring ultra-tight dimensional tolerances

Contact Geometry: Optimized roller and raceway profile for reduced stress concentration and improved load distribution

Load Capacity: High radial load capacity with enhanced axial load support in double-row or paired configurations

Rigidity: High internal stiffness, crucial for resisting deformation in machine tool spindles and precision equipment

Speed Capability: Suitable for high-speed operation, with low vibration and stable running performance

Material: High-quality bearing steel (e.g., SUJ2), with optional hybrid designs using ceramic rollers for reduced friction and heat generation

Cage Options: Precision-machined brass, phenolic resin, or polyamide cages for improved durability and high-speed stability

Lubrication: Available with grease or oil lubrication systems, including provisions for high-speed oil-air lubrication

Configuration: Single row, double row, or custom-matched bearing sets depending on load direction and application needs

Applications: Widely used in grinding machines, turning centers, high-speed spindles, aerospace tooling, and precision robotics

These parameters ensure that Super Precision Roller Bearings deliver superior performance in demanding applications that require both load-bearing strength and motion accuracy.
