Linear ball bearing individual matched composed of shaft, ball cage and housing.
Linear Ball Bearings
Preloaded Linear Ball Bearings are the ideal guiding element of modern machine and fixture design. Their smooth running (no Stick-Slip Effect), high linear resolution and extreme repeatability are only a few of their outstanding features. A large assortiment of catalogue items is paralleled with numerous custom made products. Size, shape and materials are adapted to customers requirements. We are pleased to consult you – take advantage of our more than 30 years of experience. Economically produced precision. PHZ – your partner for catalogue items as well as for custom tailored solutions. We are always one µ ahead!
The guide shafts are hardened and ground. The guide diameter is precision ground and lapped to a tolerance of ISO h3. Roundness and cylindricity is within ISO h1 and guarantees for each individually matched PHZ high-precision ball bearing high accuracy.
Ball cages are the basic component for high-precision Linear Ball Bearings. Production process and decades of experience guarantee an optimized product. The smallest units built fit 2 mm shafts and are carrying balls with 0.5 mm diameter only. A wide range of standard parts is complemented by many varieties of special designs according to customer’s drawings.
The housings are hardened and ground on all sides. The guide bore is honed to -2 / -4µ prepared for matching. The roundness and cylindricity is within ISO h1 and guarantees for each individually matched PHZ high-precision ball bearing the highest accuracy.
