HTB-FZ Kugelhalter

FZH, FZL and FZP ball retainer use bronze, aluminum, POM colophony as its base. They are machined some regular holes and embedded the steel-ball into. The new work-craft will prevent the ball getting out of as old. As the ball diameter is larger than the retainer s thickness, so it will face to face directly with guide bushing, this will bring high precision match. Now the ball retainer series items are designed to rotate on the post, as well as maintain its vertical motion. We believe this will give you the benefit of increasing accuracy.
