Product Details

Made from fabric-reinforced phenolic resin, this cage is used as a shoulder-guided, outer-ring-centered design in precision ball bearings. Its low-mass structure helps reduce centrifugal force, while the cage geometry improves lubricant delivery to the ball/raceway contact zone and supports stable running at speed. It is well suited to machine-tool spindle bearings and other compact assemblies that need rigidity, short run-in time, and dependable performance up to 120°C.

Product Advantages

Low Inertia at Speed

The lightweight cage helps reduce centrifugal forces, which is valuable in high-speed precision bearings.

Better Lubricant Delivery

The cage design helps guide lubricant to the ball/raceway contact area, improving running behavior under speed.

Proven Precision-Bearing Fit

Fabric-reinforced phenolic resin cages are a standard choice in super-precision angular contact bearings for demanding spindle service.

Product Applications

Machine-tool spindle bearing sets

used in horizontal machining centres and conventional milling machine spindles where speed, stiffness, and accuracy must stay balanced.
High-speed electro-spindles

suitable for directly driven spindle units that need controlled heat generation and stable operation at high rotation speed.
Multispindle drilling heads

a practical option for compact drilling assemblies where space is limited and bearing guidance must remain precise.
