GB 4940 GB 49 Internal Clearance Gauge Features and Advantages

Structural Design: The gauge features a groove design, where two halves of the measuring ring jointly bear the appropriate pressure of the roller assembly, effectively preventing damage to the rollers or the measuring area.

High Precision: For sizes ≤ 38 (GB 4920 to GB 4938), the precision is less than 1 μm; for sizes ≥ 40 (GB 4940 to GB 4960), it is less than 2 μm.

Adjustment Function: Equipped with adjustment screws, the gauge body can be compressed to facilitate smooth insertion into the roller assembly, enhancing operational convenience.

Application: Primarily used for measuring the internal clearance of double-row cylindrical roller bearings, it finds extensive applications in mechanical manufacturing, medical devices, power equipment, automotive industry, and aerospace fields.
