Brass ball cages are essential in stamping die sets, providing precise guidance between guide posts and bushings. The steel balls reduce friction and enable smooth, repeatable die operation at high cycle rates.
In plastic injection molds, ball cages guide the movement of mold halves with precision. Brass construction offers corrosion resistance against moisture and mold release agents.
Used in linear guide systems, sliding tables, and automated machinery where smooth low-friction motion is required, in dry or minimally lubricated conditions.
Widely used in automotive press die tooling and aerospace composite mold tooling, where precision guiding and long service life are critical.
Any standard (JIS, DIN, AISI, DANLY, FIBRO, MAHR), any size, any ball configuration. Send us your 2D/3D drawing for a custom quote. ISO 9001 certified. No minimum order.
We give value to the excellence and top class engineers, but in terms of accurate service.
