MFPT Bearing Fault (TsFile)

This dataset is an Apache TsFile conversion of odysseywt/MFPT.

Modalities: Time-series.

Overview

  • Machinery Failure Prevention Technology (MFPT) bearing dataset.

  • Vibration signals across conditions, bearing numbers, load conditions, and sampling rates.

  • Condition/bearing/load/sampling metadata are device TAGs; vibration_raw is the measurement.

  • Converted observations: 5,544,960 rows across 1 TsFile file(s)

  • Source format: csv

TsFile schema

  • Time — sample index within each segment, stored as INT64 milliseconds.
Column Role Type Meaning
Time TIME INT64 (ms) sample timestamp
condition TAG STRING fault condition
bearing_num TAG STRING bearing id
load_condition TAG STRING load
label TAG STRING label
segment_idx TAG STRING —
sampling_rate TAG STRING Hz
segment_id TAG STRING segment id
vibration_raw FIELD FLOAT amplitude

Conversion notes

  • Metadata columns kept as TAGs; vibration_raw as FLOAT FIELD.
  • Extraneous source columns (features, bearing_type, filename) dropped.

Source & license

Usage

Install the Apache TsFile Python SDK (pip install tsfile) and read a converted file:

from pathlib import Path
from tsfile import TsFileReader

path = Path("mfpt.tsfile")
with TsFileReader(str(path)) as reader:
    schemas = reader.get_all_table_schemas()
    print("tables:", list(schemas))
    table_name = next(iter(schemas))
    table = schemas[table_name]
    columns = [column.get_column_name() for column in table.get_columns()]
    print("columns:", columns)
    field_names = [
        column.get_column_name()
        for column in table.get_columns()
        if column.get_column_name() not in {"Time", "time"}
    ]
    if field_names:
        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
            batch = result.read_arrow_batch()
            if batch is not None:
                print(batch.to_pandas().head())
