Product Description
4474630 Mahr MaraMeter Self Centering Dial Bore Gage: 290-530mm/11.4-20.7″
The Mahr 4474630 MaraMeter Self Centering Dial Bore Gage – 844 NR has the following specifications:
- Measuring Range: 290-530mm/11.4-20.7″
- Error limit: 3mm
- Repeatability: 1.5mm
- No indicator included
Features:
- Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a carbide ball.
- Stationary measuring bolt can pivot through 180°, giving rise to a very long return travel path of up to 40% of the measured bore.
- Movements of the measuring bolt are transmitted to the indicating instrument via the ring segment.
- The broad centering bridge ensures automatic centering in the bore.
- Resistant to temperature because the shank and transfer rod are made of heat resistant Invar steel.
- Highly resistant to wear and tear because of carbide tipped moving anvil.
- Constant measuring force due to built-in spring, eliminating user influence.
- Universally applicable and extremely versatile as every instrument spans a broad measuring range, within this range it is quick and easy to adjust to any size.
- Extensive modular system is composed of measuring head, holder, extensions, right angle attachments and depth stops.
- Invar steel has a particularly low expansion coefficient and thus makes the instrument totally insensitive to any kind of heat. Body heat from the user, increases in ambient temperature have no influence on the measuring results.
- Scope of delivery: Measuring holder, Measuring Head, Anvil spindle, Wooden case, excludes indicator.
