HC71912C.T.P4S.UL Angular contact ball bearing Spindle Bearing 71912 USMA Ball Bearing HC71912E.T.P4S.UL

The HC71912C.T.P4S.UL is a high-speed spindle bearing designed for precision applications, featuring hybrid ceramic ball construction. Below are its key details:

Specifications:

• Model: HC71912C.T.P4S.UL (Angular Contact Ball Bearing, 15° contact angle)

• Type: Hybrid Ceramic (Si3N4 ceramic balls + steel rings)

• Precision Class: P4S (Ultra-precision, superior to ABEC 7)

• Cage Material: Typically phenolic resin 

Key Features:

1. High-Speed Performance:

• Ceramic balls reduce centrifugal forces, enabling higher RPMs than all-steel bearings.

• Lower friction and heat generation.

2. Extended Service Life:

• Ceramic balls resist wear and minimize electrical arcing in motor applications.

3. Rigidity & Accuracy:

• P4S (ABEC 7+) precision ensures minimal runout for spindle/machine tool use.

4. Thermal Stability:

• Si3N4 balls have lower thermal expansion than steel, maintaining preload under temperature fluctuations.

Applications:

• CNC spindles

• High-speed machining centers

• Electric motor spindles

• Precision grinding machines
