Grinding The Spacer   INST 101.1

Service Bulletin: INST 101.1

Subject:  Grinding The Spacer

Recommendations: 

1. 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)
2. 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.
3. 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.
