GB 10 internal clearance gauges enable simple and accurate measurements when mounting cylindrical roller bearings with a tapered bore in precision applications. They are used to measure the outside envelope diameter of the roller set when the rollers are in contact with the inner ring raceway. Based on these measurements, the radial internal clearance or preload can then be precisely adjusted.

• Used for measuring the outside envelope diameter of roller sets
• Enable precise adjustment the radial internal clearance or preload
• Intended for a particular bearing size
• Useful also for other than precision applications
