LBB and Components
Linear ball bearing individual matched composed of shaft, ball cage and housing.
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.
