1) NOTE: Where bearings are relubricated in service, limiting speed is reduced to 75% of tabled speeds.
2) * Extended bearing width requires special spacer rings

MOUNTING PRECAUTIONS
1. Radial internal clearance of sealed spherical roller bearings
cannot be measured by feeler gauges. When mounting tapered Table 1 Assembly of self-aligning
bore bearings on adapter sleeves, axial drive-up method roller bearings with tapered bores
must be applied to ensure correct mounted clearance. (1/12 taper, mm)
Refer to Table 1. for axial displacement distances.

2. Due to extended bearing width in some cases special spacer d
rings (marked *)are required for fixed bearing location, in O V E R N I C . L . N I M M A . X
