HCB7015-C-T-P4S-UL Ceramic Bearing
Complete Designation Breakdown
The specific alphanumeric code details its structural features, tolerances, and design parameters:
-
HCB: Hybrid Ceramic Bearing. Features standard steel inner and outer rings matched with high-grade silicon nitride ceramic balls.
-
70: Dimension Series 70. This signifies a light-series design optimized to balance load capabilities with high radial and axial rigidity.
-
15: Bore Size Code. Represents an inner diameter of 75 mm(calculated by multiplying \(15 \times 5\)).
-
C: Contact Angle. Features a 15° contact angle, optimized for applications requiring ultra-high speeds and high radial stiffness.
-
T: Cage/Retainer Type. Equipped with a laminated fabric window cage(phenolic resin retainer) guided by the outer ring, designed to handle minimal weight and rapid rotational speeds.
-
P4S: Precision Class. Represents FAG Super Precision standard, which exceeds traditional DIN P4 (equivalent to ABEC 7) tolerances for runout and rotational accuracy.
-
UL: Universal Design & Preload. Universal matching capability (U) configured with a Light (L) preload. It can be mounted as a single bearing or combined into pairs/sets (such as DB, DF, or DT configurations).
