⁉️ FAQ - Frequently Asked Questions

Q1: What is the contact angle?
A: 25°, enabling significant axial load bearing while maintaining radial strength.

Q2: What does P4A precision mean?
A: It’s a super-precision class (ABEC 7), delivering minimal runout and extreme accuracy.

Q3: Can I pair them without shims?
A: Yes — universally matchable, they work in pairs with preset preload.

Q4: Where are they used?
A: In spindles, CNC machines, precision gearboxes, servo motors, and automation systems.

Q5: What speed and load ratings apply?
A: Designed for relatively high speeds (up to ~13,000 RPM grease, higher with oil-air) and heavy load conditions.
