Subject: Grinding The Spacer
- With the clamp ring spacer in place, use a depth micrometer to measure the distance from the face of the clamp ring spacer to the bearing shaft mounting surface. Record this measurement as (A). See Figure 1. (A) = distance from face of clamp ring spacer to bearing shaft mounti ng surface (b) = distance from roller flange to bearing shaft mounti ng surface (C) = amount to grind from the grind spacer (A) – (B) + 0.001″ = (C)
- With the bearing installed in the roller. Mount it along with the unground spacer to the bearing shaft. Move the assembly to a surface table and use a depth micrometer to measure from the roller flange to the mounting surface of the bearing shaft. Record this measurement as (B). See figure 2.
- Subtract dimension (A) from dimension (B). Add 0.001″ (for clearance). This will be the amount to be ground from the grind spacer (C). See formula below.
