Anderon — dumalanish elementli podshipnikning tebranishini ifodalovchi birlik bo'lib, 1 μm/s RMS tezlikka teng. U podshipnik sanoatida (Anderson o'lchov asbobi nomidan olingan) ishlab chiqarish sifat nazorati jarayonida 1800 RPM standart tezlikda podshipnik tebranishini miqdoriy baholash uchun ishlab chiqilgan.

ISO 15242 defines methods for measuring vibration of rolling bearings. It specifies three frequency bands: Low (50–300 Hz), Medium (300–1800 Hz), and High (1800–10000 Hz). Each band captures different defect types. ISO 15242 defines the measurement method only — it does not specify acceptance limits.

Chastota diapazonlari nimani anglatadi?

Low band (50–300 Hz): waviness of raceways. Medium band (300–1800 Hz): surface roughness and minor defects. High band (1800–10000 Hz): micro-defects, contamination, and noise. Acceptance limits for each band are set by the bearing manufacturer or agreed between manufacturer and customer — ISO 15242 does not specify them.

μm/s ni Anderon birligigiga qanday aylantirish mumkin?

1 Anderon = 1 μm/s RMS velocity. So the conversion is direct: a measurement of 50 μm/s = 50 Anderon. The measurement is typically performed at 1800 RPM inner ring rotation with outer ring fixed.

Sifatli podshipniklar uchun odatdagi Anderon chegaralari qanday?

ABEC-1 (P0) podshipniklari uchun: Past diapazon < 50 And, O'rta < 40 And, High < 35 And. ABEC-5 (P5) uchun: Past < 25 And, O'rta < 20 And, High < 15 And. Precision grades have even tighter limits. These are representative industry values, not ISO 15242 limits — always check the bearing manufacturer's acceptance specification for the exact bearing type and size.

ℹ️ Note: ISO 15242 defines the measurement method and frequency bands only — it does not set acceptance limits. The values above are representative, manufacturer-style guidance; per ISO 15242, acceptance limits are agreed between the manufacturer and the customer. Always consult the bearing manufacturer’s acceptance specifications for your exact bearing type and size.
