HCB71916-C-T-P4S-UL Part Number Breakdown
-
HCB(Hybrid Ceramic): Steel rings with silicon nitride (Si3N4) ceramic balls. Minimal heat generation, significantly boosting speed limits.
-
719(Dimension Series): Ultra-light and thin series. Small OD and narrow cross-section, ideal for compact, high-speed spindles.
-
16(Bore Code): Represents a bore diameter of 80 mm(calculated as 16 multiplied by 5).
-
-E(Contact Angle): 25° contact angle. High radial load capacity, allowing maximum rotational speeds.
-
-T(Cage): Outer ring guided, laminated phenolic resinsolid window-type cage. Light and wear-resistant.
-
-P4S(Precision Class): Dimensional tolerances meet P4 (ABEC-7), running accuracy exceeds P2 (ABEC-9).
-
-UL(Preload & Matching): Light preload, universal design. Can be freely matched in O-arrangement (DB), X-arrangement (DF), or Tandem (DT).
Primary Applications
-
CNC Machine Tools: Motorized spindles and high-speed cutting spindles.
-
Precision Grinding Machines: Workhead spindles requiring high stiffness and low runout.
-
Instrument Testing: High-precision shafting systems for inspection equipment.
-
High-Speed Transmissions: Rotational mechanisms with strict temperature rise control.
