UCFL204 pillow block bearings

1. Bearing type: Different types of bearings have different requirements for matching. For example, for radial bearings, the load size is to be divided by the ratio of radial equivalent dynamic load Pr to radial rated dynamic load Cr. If the load is larger, then the interference of the fit will be larger.
2. Bearing type: relative to the load direction for rotation or swing of the ring, it is necessary to choose interference fit or transition fit. For the fixed load direction of the ring should be used to match the gap. When the non-separable bearing is used as a support, it is necessary to use a ring that is fixed relative to the direction of the load as a traveling ring, and choose a clearance fit or a transition fit.
3. Bearing seat size: When the size of the bearing seat changes, interference fit will also change accordingly.
4. Bearing clearance: interference fit will lead to the reduction of bearing clearance, it is necessary to check whether the bearing clearance after installation can meet the requirements of use, and then select a more matched bearing clearance.

It should be noted that the inner ring and outer ring of the bearing are matched with the bearing seat by the base hole system, and the tolerance zone is below the zero line and the upper deviation is zero. The tightness of the fit needs to be adjusted according to the actual situation, and the interference amount should be between 1-3mm. If the bearing fit is too tight, it will lead to increased bearing running noise and may accelerate bearing wear. If the bearing fit is too loose, it will lead to unstable bearing operation and may damage the bearing seat
