Install these ball transfers in a threaded hole or use a nut to secure.

Weight capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the weight capacity stated.

Test your coordinate measuring machine (CMM) probe and stylus against a precise reference point before you start inspecting. These spheres come with a calibration certificate traceable to UKAS (United Kingdom Accreditation Service) that confirms their accuracy. Made of tungsten carbide, they won’t lose their precise shape or size over time.

To prepare your probe for different inspection angles, adjust the angle of the sphere. For example, if you need to measure underneath a part, angle these spheres down to 45°. They rotate 360° even when angled. They snap into place when they’re perfectly vertical, the most common position. After you’ve positioned these spheres how you want, lock them in place by tightening the collar. Each time you adjust the sphere, you’ll need to recalibrate your probe and stylus.

Smaller spheres are best for probes with smaller stylus ends. As a rule of thumb, you should use the 25 mm dia. sphere for any stylus with an end diameter over 2 mm.

Secure trailers to vehicles by locking the hitch pin into the receiver—you can't disconnect the trailer without the key. Use them to prevent someone from stealing your trailer or moving it. Built to stand up to any weather, they're great for outdoor trailers. The lock body rotates around your hitch pin, so you can easily reach the key into the cylinder to unlock. A plastic cover protects the key cylinder from water and debris, so it won’t freeze, corrode, or jam.
