CRL44 Bearing Installation Guide:

1. Confirm part: Verify designation (CRL44 bearing), clearance class (e.g. Normal, C3), cage material, and any special features before opening sealed packaging.

2. Cleanliness: Work in a clean, dust‑free area. Wipe the shaft, housing bore, shoulders, and tools with lint‑free cloths. Any abrasive particle will shorten service life.

3. Dimensional checks: Measure shaft journal and housing bore with micrometers in several planes. Confirm they fall within the tolerance for the intended fit.

4. Handling: Keep the roller/cage assembly and rings together until just before mounting. Do not spin the bearing dry with compressed air. Support the full inner ring face when pressing; never transmit mounting force through the rollers.

5. Mounting: Often the inner ring is mounted on the shaft first (if it is a separable type and the roller/cage is retained with the outer ring, or vice versa depending on design).  Heat the inner ring evenly using an induction heater or oil bath to about 80–100 °C (never exceed manufacturer limit, commonly 120 °C). Do not flame heat.
